How to find airgun leaks & what you can do about them

By B.B. Pelletier

How do you find a leak in an airgun? What do you look for? For that matter, WHERE do you look? We’ve talked about O-rings, seals and how Pellgunoil miraculously seals a gas gun. But I never told you how to find the leak in the first place! Now’s the time!

I’m forever blowing bubbles…
…and so are pneumatic and gas guns that leak! Soapy water is the traditional way to find air leaks. Airgun repair shops keep a soapy solution around for this very purpose, and you can use the same method. Get some dishwashing liquid, mix it with a little water in a small drinking glass, apply the soapy solution to the places on your gun suspected of leaking. If there’s a leak, you’ll see bubbles forming in the soapy solution!

What if the leak is deep inside the gun?
Not all leaks are found by the first method, so there’s another way to detect leaks that are deeper in the gun. Wipe a film of soapy solution across the muzzle of your gun with your finger. If the valve is leaking at the exhaust side, your muzzle will blow bubbles.

In a hurry & no time for soap? Try this!
If you’re in a hurry, here’s a fast way to find leaks: stick the muzzle in a basin of water. If it blows bubbles, the valve leaks. I’ve used a toilet bowl in a pinch (for testing airguns, of course!). Remember, you are putting only the muzzle in basin of water – not the whole gun or even the entire barrel!

Do NOT leave water on your gun
Guns and water don’t mix well, so make sure you dry the gun completely after any of these tests. I don’t think a towel will do a good enough job, so I suggest that you use an air hose or some other kind of forced air. Dry-firing the gun several times is a good way to dry any water that’s in the barrel. After you’re sure it’s dry, wipe down the gun with a good oil. If it’s a CO2 gun, shooting a Crosman Pellgunoil CO2 cartridge through the gun would not only be the perfect way to finish the after-testing maintenance, it might even seal the leak!

Sometimes, you can hear the leak!
Sometimes you can hear where a gun is leaking if it’s a fast leak. You need to be in a quiet place, plus it helps to cup your hand around the gun parts you suspect of leaking. If the leak is fast, this is a quick way to pin it down.

What about sloooooooow leaks?
There are leaks so slow they are next to impossible to find in the traditional way. Like magnesium car wheels that become porous after driving on salted streets, there are airgun leaks that may never be found. You have to be reasonable. Most of my airguns hold their charge for years, but I have a vintage Crosman pump that loses its one-stroke maintenance charge in two weeks. The solution has been to pump it twice when I want to leave it a long time, and to check it every six months. So far, that’s worked. Don’t throw the baby out with the bathwater!

Let me know how you find leaks!

  1. I have a VERY BIg leak in my Daisy 15TX. When ever I put a fresh CO2 capsule it discharges the whole thing. Can you help?


  2. What you have is called a fast leak. Have you tried using pellgunoil yet? It can sometimes fix a fast leak, too.

    You migh try a Crosman maintenance kit, which is essentially a powerlet with oil inside.

    The point is to shoot the gun while it is leaking so the oil gets blown through the entire valve and coats all the seals.

    Tell me what you’ve done already and where your gun leaks (read the posting again) and we’ll see what more can be done, if anything.

  3. well thanks fopr the tips, I finally got it under control. I did’nt use the Crosman oil, I used an oil for singer sewing machines. I’m amazed that it does’nt fast leak anymore. I’m still looking in to see if there is still any little leaks. Thanks!


  4. Thank you so much for your feedback. I think I’m as glad as you are when things happen the way they should.

    I didn’t know Singer oil would work, but you can’t argue with success.

  5. This is a stupid question but I am new at this. I bought a Crossman CO2 pistol and it is great. I fired off about 8 test shots and then when I went to put the gun away, I unloaded it and took out the CO2 cartridge, which never worked again.

    My question: Can I leave a CO2 cartridge in even if I don’t use the gun often and keep it in a case in a closet? It seems a waste to fire a few shots and then lose the whole cartridge. What is the best way to store a gun like this and still make the best and safest use of the various components?
    –A


  6. Sorry – my model is a Crosman 1008B. Cannot find anything in the manual that says if it is safe to leave the cartridge in or not. And if it is safe, what is the highest indoor room temp the gun can stay in and not have problems?


  7. Alice,

    You can leave the CO2 powerlet in some guns for years without damage or danger. I am testing a Crosman 2240 pistol right now and I’ve left it charged with the same powerlet for three months. I have other Crosman guns in my collection that have remained charged for several years. I once bought a Crosman model 111 pistol that had kept its charge for about 20 years.

    The only guns where leaving a powerlet installed is not recommended say so in the owners manual. There are a few whose design is more fragile and they can develop problems if left charged. If there is no warning in the owner’s manual of your pistol, I would say go ahead and leave it.

    B.B.


  8. Thank you SO much. Great website and information.

    One last question. I live in a city but have a small backyward that is overrun by racoons. The city won’t trap and take them away and I can’t go outside with a shotgun either without scaring the whole enighborhood. Would a pellet gun deter or actually kill and/or seriously injure a racoon? I want to scare them off but don’t want injured and angry racoons lying around the yard. What about plastic BBs?


  9. Alice,

    You know, I don’t have any experience in deterring raccoons. Pellet guns will kill tham humanely, but that doesn’t sound like what you want to do. My brother-in-law trapped six of them in a Have-A-Heart trap and drove each one about 20 miles before releasing it. That sounds like a lot of work to me.

    Also, please be careful! Raccoons are prime carriers of rabies!

    Maybe one of our readers has a little more experience than me. Have you spoken to your county or state wildlife services office about this?

    B.B.


  10. What do you do if the gun has some serious leaks in the gas tubing, can I just glue and seal the tubes back into their positions?
    Thanks


  11. What model gun do you have? Since CO2 is at 900 psi, gluing doesn’t usually work. A new set of valve parts might be required.

    Have you done the Pellgunoil fix yet?

    B.B.


  12. Hi, its a crossman 357 – 6 shot revolver, I recently purchased it- was told it was in good working condition, instead of taking it back to the guy i bought it from, i was sure I could fix it, but as I was removing parts the charged gas cylinder blew a few parts away, including the tubing.
    Now when you place a fresh cylinder into the gun, it empties in a few seconds as the tubes are not sealed.



  13. New Zealand,

    You need serious help with that 357. Pellgunoil won’t fix it. It needs a rebuild.

    Are there any Crosman repair stations on New Zealand?

    B.B.


  14. Gamo 1250,

    Get a good set of rings with the scope stop pin built in. The recoil from a Gamo 1250 isn’t strong enough to bend a scope stop pin unless it was made from unhardened steel. I suspect you were using inexpensive (Gamo?) rings. They won’t take that kind of stress.

    B-Square or AirForce rings will be strong enough for your gun.

    B.B.


  15. I have thought about taking it into the shop but my other half is already upset about spending $ on what is now a pile of parts.
    I have all the parts and know where they go, but just need the tubes etc sealed.




  16. When I put the co2 canister into my gun, it leaks and sprays everywhere and is empty in about 5 seconds. Is there supposed to be a rubber washer or a seal? I’m trying to fix it for a friend. It’s a Crosman 357 air pistol. Might the oil work for it too?



  17. 357 fixer,

    It sounds like you are missing the seal that the powerlet butts against. It’s a thin synthetic seal. I don’t know if Crosman will sell them to the public, but you could ask.

    If not, the gun has to go to a repair station.

    I doubt the oil trick will help in this case.

    B.B.


  18. I have a Bengamin Sheridan HB17 air pistol which I use to scare off raccoons that are eating our garden. The pistol is only a year old, has been fired only about 50 times, is NEVER pumped more than 3 times (I don’t want to kill), and now it leaks through the barrel. I can hear it. One shot it was fine, the next it was leaking. I called Crosman, they said oil it. The manual only has instructions for oiling pivots. What can I do at home? Do I need to send it way for service?

    Any insight you could provide would be most appreciated.


  19. lagbolt1138,

    Have you stored your gun with a pump of air in it? If not, start doing that now.

    Your problem is your seals are hard and dried out from exposure to the air. Oil the pump head by turning the gun upside down and opening the pump handle as far as it will go. The pump head will barely be visible at the end of the pump slot. Drop four drops of Crosman Pellgunoil or any PURE silicone oil (edible oil only!) on the pump head And work the pump handle for 30 seconds to spread the oil.. Don’t use 3-in1, WD-40 or any household oil or the gun will have to be stripped and repaired.

    After oiling, pump the gun eight pumps and shoot it with a pellet. Do that 10 times. Then put two pumps of air into the gun and let it sit for a day. In 24 hours, cock the gun and shoot it. It should still be holding air. If so, your gun is fixed. Store it with a pump of air in it at all times.

    If that doesn’t fix it, you can try the same procedure again, or write me and I’ll tell you where to get it fixed. Stored with air in it, your pistol should last 30-40 years.

    B.B.


  20. BB-

    Wow. Good stuff there. I will try it tonight. Thanks!

    While I have you…another question.

    My wife has difficulty with the pumping of the HB17. She’s not nearly my size, so we’re considering a CO2 BB pistol for her on raccoon watch.

    How long will a CO2 cartridge (CO2c) hold pressure in a pistol after installed? Using up an entire CO2c for just a couple of shots is wasteful and expensive. Since budget is an issue, especially on such a low use item, can you recommend some mfgrs or models to look at or avoid? It would be best to have something ready for use, than to waste time on set up.

    Thanks!


  21. An airsoft gun will scare a critter without damage, while a BB can possibly break the skin.

    You can buy a good automatic electric gun that runs on batteries for under $30.

    Look under Airsoft and then under electric mini machine guns on the Pyramyd Air website.

    B.B.


  22. BB-

    A quick follow-up on your air leak fix for the HB17 (see 06 June posting). The oil procedure you recommended worked perfectly. Thank you so much for time and expertise.


  23. i have a crossmen power master model 760, i’ve had it for 10 years and it just started leaking out the barrel and im stumped, any help would be appreciated


  24. BB,

    I have a Crosman Model 73 CO2 rifle. I think it dates from 1976, and has probably never been oiled.

    After years of sitting on a shelf, I tried to get it working again. When I insert a CO2 powerlet, most of the time I get a fast leak that empties the cartridge in 5 – 20 sec. I have tried to use WD-40 and some oil to seal the leak (not Pellgunoil), to no avail. Do you think I made the problem worse? What do you think I should try next?

    Thanks for the great site.
    -JCG


  25. JCG,

    Well, the oil and WD-40 didn’t do it any good. WD-40, especially, is very rough on fine working parts. It’s great for drying distributor caps, but who has one of those anymore? I love the smell, but when I saw what damage the varnish it leaves can do to a fine firearm, I stopped using it altogether.

    I would say that the best thing you can do now is to send your rifle to a good Crosman repair station. Here is the best:

  26. Hello! I have an old Crosman 760 purchased around 1976. It’s still a good gun, but recently it’s developed some kind of leak. The first shot is always fine, but after that, it won’t hold any pressure and it’s a really weak pffffft no matter how many times I pump it. Then I let it sit for a day or so and it’s fine for the first shot again, but after that, no go. Is there any way to tell which seals or valves need to be replaced, where can I find parts and how do I go about it. I’ve already disassembled the gun about as far as I can but I think there are still some parts in the barrel. Thanks!


  27. There are no parts in the barrel. The entire valve is housed in the pump tube under the barrel.

    You can call Crosman and see if they will sell you the parts you need, or you can send the gun to an airgunsmith. I recommend this guy:

  28. i have a hahn 45 co2 bb gun its old i just recieve it from my grandpa i put a co2 cartridge in it when i go to shoot it leaks where the inlet is sprays out like and five seconds then its emtpy. what do i do


  29. You get it resealed, then you never put another cartridge in it without putting a drop of Crosman Pellgunoil on the tip of the cartridge beforer it is pierced.

    This place can reseal it for you:

  30. I have a Crosman model 1077 repeater rifle. It’s been sitting for about ten years because it developed a fast leak so I just put it away. Now my neighbor is having that raccoon problem that it seems, everyone is having so we need to try harsher measures. He’s already trapped 8 of the critters. Thing is, our township and county want nothing to do with them. They said to call private animal control people who, by the way, get big $$$ for their work! Town told us that you CAN NOT trap them and drive them to a remote location as it’s a crime to transport wildlife ANY DISTANCE without a license. Private pro suggested .22 cals or 12 gauge. Right…..at 2 am with neighbors sleeping 20 – 30 feet away.

    Anyway…..want to get the gun working so as to put a little “scare” in them. Can’t kill them cause we can’t dispose of them without getting arrested so….where do I start with this leak thing? After I put the cart in you can hear it hissing.

  31. got my hands on crosman 38t 177 air gun. I don’t know much about it. I bought a box of 5 CO2 gas and pelts. Placed CO2 and took one shot at night, placed the gun on table only to hear hesssssssssing while watching tv. The CO2 gas gone. I took gun apart in the morning tried different things placing CO2 cartg till I used all. It is leaking gas and I can’t find out from where? some gas came thrugh the cylender some through barrel. Please help Thanks….


  32. Before you disassembled your 38T I believe it could have been fixed by the use of Crosman Pellgunoil on the tip of a new CO2 cartridge. However, at this point, the gun probably needs to be rebuilt.

    This place can do the job:

  33. B.B.

    Yes I understand that, but I meant for FIXING leaks, not finding them.

    That's my fault, I should have been more specific.

    Pellgun Oil IS great stuff & HAS fixed a number of leaking guns of mine. But in my experience, usually just the slow or moderate leaks. Not the ones that completely empty a CO2 cart in a matter of seconds.

    I have a couple of REALLY bad leakers like that, & while of course I don't expect Pellgun Oil to work every time & especially not on guns where the seals are totally shot, I'm just trying to find out what will give me the best chance.

    The description of the cleaning kit says;

    "Includes two Pellgunoil Lubrication Cartridges and 100 felt cleaning pellets."

    Since Crosman doesn't say how much oil is in their Lubrication Cartridges, I'm just wondering if they are more efficient or will work better, as opposed to putting a several drops of Pellgun Oil on the inlet, & also a couple on the tip of a plain CO2 cart?

    I've actualy saved some pretty bad leakers by doing that a few times.
    It didn't work the first time, but the second time it seemed to slow down a little, & by the third or fourth time, it DID work. :)

    So I was just wondering if the Lubrication Cartridges would work better, & save some guns that my method won't.

    - The BBA -



  34. B.B.

    Yeah… That makes sense.

    The more I think about it, how much oil is really in those lube carts? Five or six drops?
    Even if it were more, my method would still eventually get the same amount of oil in the same places, within a couple of tries or so.

    I guess it was just wishful thinking, hoping maybe there was something I didn't know about them, but the more I think about it, it's like you say… Either way, it's going to do the same thing.

    Thanks for the input & bearing with my silly questions lately.

    It's been a rough month, so my brain is scrambled right now, & I'm finding myself second guessing everything.

    Thanks again,

    - The BBA -



  35. Alexander,

    Your gun has a leak that has to be repaired. A seal is bad. Have you always used Pellgunoil with every new cartridge? That can prevent this from happening, but sometimes the seals just fail.

    Contact Crosman for repairs unless the gun is under warranty.

    B.B.


  36. I got an old crosman 38c from my dad put a co2 cartridge in and it all leaked out. so I’m soaking the cylinder with the air parts in tranny fluid this should swell the seals. but if it don’t where is this guy in Pa? thanks



  37. I have a Daisy Powerline 990, you can hear air leaking out when you pump it more than 7 times, it seems to be coming from around the chamber. How can I fix it?



  38. I put Hoppe's 9 Lubricating Oil on it about an hour ago. But it still does not work, should I try the other oils?


  39. Well, Hoppes may have ruined the gun!

    It may need a complete rebuild now.

    That's why I specified Crosman Pellgunoil or 20-weight non-detergent motor oil. Nothing else works. Your owner's manual should have mentioned that.

    Because it is a Daisy, only Daisy will repair it.

    B.B.


  40. B.B.

    I have a Crosman 357 Co2 powered air pistol. I used WD-40 on the end of one air cartridge before knowing what sort of harm it would do to the airgun (that was a stupid idea).

    Now the airgun is no longer consistent with each shot I fire. i.e. I fire one shot and its perfectly normal, then I fire another shot and the velocity of the pellet goes down by half etc… But when I wait for about 60 seconds after each shot the velocity of the pellet returns to normal. I don't hear any leaks and I just got this gun about a month ago…

    Would Crosman pellgunoil fix this problem? Or would this problem fix itself over time? What would you recommend?


  41. I had this exact problem filming a shoot for American Airgunner today! The problem is not lubrication. It is the piercing needle that isn't puncturing the CO2 cartridge deeply enough. It leave a small hole the gas can eventually get through.

    Either the piercing pin has to be replaced or you need to screw the cartridge in tighter.

    B.B.


  42. Or you need to shim the bottom of the cartridge like I had to do on my crosman mark II since the piercing needle had been worn significantly. I put a doubled over thickness of paper towels at the bottom of the co2 cartridge, then put pellgunoil on the tip of the cartridge. After 3 cartridges the gun shot like it was new. I'm convinced that B.B.'s pellgunoil was as significant to this "fix" as adding the doubled paper towels to increase cartridge penetration.

    kevin


  43. Good point! I'll give that a try. I think I might need to replace the piercing needle though because I don't hear that discrete hiss when I screw the cartridge in.

    Thanks!


  44. Thanks Kevin! I will also give that a try without replacing the needle first. I thought the WD-40 contributed to the problem or messed up the seals badly… I'll have to give pellgunoil a try!

    Thanks!


  45. Anonymous with the piercing needle problem,

    Please visit the link I provided. There's some interesting comments to your questions from experienced airgunners waiting for you there.

    kevin


  46. Anonymous,

    I would like to add that when using Pellgunoil, sometimes you have to go through a number of carts before it starts to work.

    I had one gun that took 6 carts with putting pellgun oil on them before the leak finally stopped.

    So, if it doesn't fix it the first time, don't give up.

    Hope this helps,

    BBA



  47. Anonymous regarding the piercing needle problem,

    My apologies. I confused you with another airgunner.

    I am going to give you a link though.

    You posted your question under an article that B.B. wrote back in 2005. Not many airgunners check back on these old articles. Most are asking and answering each others questions in the "comments" under the most recent article that B.B. has written (B.B. writes a new airgun related article every day, Monday-Friday). Here's the link (you will need to copy and paste) that will always take you to the most recent article that B.B. has written:

  48. i have a 38t, hapve taken it apart to investigatet a full blown leak. I have two 0 rings that are bad. Looking for replacements. cannot find on the internet—-

    HELP




  49. okay, can someone really help me please. Here the story. I bought a Umarex SA-177 air pistol and for about a week its very nice and very good. Everything works fine, no leak or nothing. Well I'm the type of person who likes to keep gun loaded with C02 in it. For some reason when i pull back the Co2 out and put a new one in, the C02 just leak out fast, which if I don't tighten up the seal and if I do tighten up the seal, it will continue to leak slowly. By looking at the puncture seal, noting seem to be wrong. I even tried pellgun oil but it still had the same problem. I thought it might be the tightener (the screw that push the Co2 up and tighten it), but it's not. I can't find a solution to fix it. Can anyone please help me here, or at least some advice. Thankx


  50. Hi, i have a power master 760 bb gun. When i pump it the air leaks out of the barrel and i don't know what to do can you help me? Thanks



  51. Anonymous, basically you've got a leaking valve.

    I don't think those 760's are particularly difficult to repair, at least if you're reasonably good with your hands. And parts are pretty easy to get – at least for some variants. I did a couple of older ones earlier this year.

    If it's a recent vintage it might not be worth the trouble of fixing. But if it's an older one you might wanna take a shot at it yourself.

    Maybe someone here can help you out:

  52. I have a Walther P99 DAO CO2 blowback airsoft gun and it just recently started a fast leak. Its really pissing me off. Ive wasted like 8 cartridges and still cant seem to fix it. Ive tried putting hockey tape on the cartridge to get a tighter fit but it didn't work. Any ideas?


  53. Anonymous,

    unfortunately, you've posted your question on a blog that's 6 years old! Only a couple of us monitor these old blogs. Re-post your question on the current blog. Try:

    If that link doesn't work for you, use:

    http://www.pyramydair.com/blog

    Now, have you been putting any oil on the tip of your cartridge before inserting into the chamber? If not, probably your seals are a bit dry so try that. Pellgun oil is recommended but you can get away with 20 or 30 wt. motor oil. That may slow the leak and even stop it. The hockey tape won't help at all.

    Good luck.

  54. hello, im not inquring about an air rifle persay, but about an airsoft rifle. i have a L96 Bolt action sniper rifle and i bought it used, he had it for about a month, and claimed it was in "very mint condition" he listed that it came with silicone oil as well, so im assumed he had maintained it well. when i recived the gun, it was excessivly oiled with WD-40 and i was wondering if there is any way to replair it without a huge budget. it doesnt have enough power to accuratly hit a pop can 30 feet away.
    HELP!!

  55. Hi there

    I have a Crosman 1008 which has performed fine for the four years I have had it. I have never had a leak problem until the other day when I finally followed the instructions and put a drop of Crosman 241 Pellgunoil on a fresh CO2 caplet. Now it leaks (fast leak).

    Any advice? Thanks in advance.

    Ian


  56. Ian,

    First of all, the Pellgunoil didn't cause the leak. Second, a fast leak is a seal problem. An o-ring might have hopped out of its seat or you might have torn the face seal when installing the last powerlet.

    At any rate, your gun needs to be resealed.

    Then ALWAYS use Pellgunoil.

    B.B.



  57. Dear B.B

    I have just recently bought a Crosman 760, and It's shot very nice groups (for the price), and the power is great for backyard plinking when pumped 10 times……however, when I pump it, I hear a 'swish' sound for a fraction of a second when I have opened the pump lever all the way……is this a problem, or does the cromsman 760 make a bit of a sound when you pump it ??

    Cheers,
    AJ


  58. AJ,

    Think about what is happening when you pump. The piston, or pump head, is being withdrawn from the compression chamber, creating a vacuum inside the chamber. When the piston passes the air inlet, air rushes into the compression chamber. That is the air you compress on the next pump stroke.

    All multi-pumps have a swishing sound when the pump handle is opened all the way.

    B.B.


  59. I have a ultra-fast leak, one that drains the tank in about 10 seconds. It's pretty intimidating with a "smoking" gun near me. It leaks from well…everywhere.

    I was told by the manufactor to get an o-ring rapair kit, and that it maybe at Cabella's. However, Cabella's must have something against the South East U.S., I mean it looks like a hole in the map. I can't find anything like that online, except for an air rifle repair shop that would charge more than my gun (which is worth $70)

    I'm not attached to the gun (maybe a tiny bit) but I don't want to get a new one simply because I don't want to spend the $50-$100 on it. What do you reccomend I do?

    please e-mail me at jas11101@gmail.com ; this is my spam account btw, just in case.

    Thank You!


  60. huntingmachine,

    It would help if I knew what kind of gun you have. But it sounds like you are talking about a CO2 gun. Your leak sounds like a torn face seal, located where the cartridge gets pierced.

    Have you always used Crosman Pellgunoil on the tip of evey new cartridge when you installed it? That and not over-tightening the cap are two things that preserve the face seal.

    Tell me what gun you have so I can tell you what to do next.

    B.B.



  61. huntingmachine,

    I doubt you hurt the seal by dry-firing the gun. There is no relationship between the inlet valve and the firing mechanism that I am aware of.

    But the P23 does have a thin face seal. I bet that's what it is. It could have been damaged by not oiling every cartridge with Crosman Pellgunoil, or by over-tightening the CO2 cartridge screw when you pierced the cartridge. A lot of times we think that screw needs to be very tight to prevent leaks, when the opposite is the case.

    In any event, I think your gun needs to be resealed. If Gamo won't do it for you, perhaps Pyramyd Air will.

    Of course the P23 is so inexpensive that there is a point beyond which it's cheaper to buy a new gun rather than to fix the old one.

    Just remember to always use Pellgunoil from now on.

  62. Hay I have a 15 year old power master 760 it's leaking after 5 pumps I suspected it was the o ring took it apart and replaced it and it's still leaking I really need some help with this



  63. Guys any one please I have air soft pistol pro77 when ever I put co2 it empty it in 2 or 3 seconds just from every where any vedios or some one to call????? Any tips


  64. When they empty fast like that the seals are gone. You need to have the gun resealed. Pyramyd Air can do the work.

    Sometimes over-tightening the CO2 screw when the powerlet is pierced is what ruins the seal.

    Just use Pellgunoil on the tip of each new cartridge after the gun is sealed and stop tightening the screw the moment it hisses. It will seal instantly that way.

    Good luck

  65. I have a Crosman 22 cal. 38T pistol. It is all metal. I bought in the early 1970's. I tried touse it one day and the co2 poewllet just discharges right out. Also the new pellets seem to move forward and stop it from revolving. The manual says to use super pells. Don't know where to find them of pelgunoil. Any ideas?
    Thanks, Pat


  66. Pat,

    put a drop of motor oil (20 wt is recommended but 30 wt will work just fine) on the tip of the powerlet and install it. The seals are probably hardened from age and also very dry. If that doesn't work (and you may have to do it two or three times), the gun will have to be re-sealed. As for pellets, they aren't moving forward due to the CO2 cartridge being exhausted from a leak.

    One last thing, keep in mind this blog is 7 years old and very few of us monitor them. Feel free to ask your questions, off topic is always welcomed) on the current blog.

    Good Luck.

  67. This stopped my gun from leaking… 100%. Take a
    latex glove and cut a 1/2 sq in. and pull over the
    neck of the new CO2 . this will need to be stretched
    a little . It is almost self holding, but just wrap very
    small rubber band or the tail you cut of the glove around serveral times. Works like a charm.. Crowhunter…..


  68. I have a Ruger p95 and while gassing up I accidentally didnt screw it in all the way and it leaked all out. I quickly put it on the bathroom floor,shut off the light, turned the fan on and let it be. But the question is the gas WONT kill me if I go in there right as of now its been in for around 10 mins.


  69. Bryce,

    Well, I'm guessing that you did finally go into the bathroom and the gas didn't kill you.

    CO2 is not poisonous. It simply displaces air and we cannot breathe it and live. Since it is much heavier than air it goes to the floor and is dispersed within a few seconds.

    To be dangerous the way you described, you would have to be in a very small airtight room with the CO2. Such a room would eventually suffocate you naturally, since you exhale CO2 with every breath.

  70. HI I have a crosman 357 10 shot revolver,and when i put a new co2 cartridge in it goes out in like 2 min and i can see the leak.what can i do


  71. Put a drop or two of Crosman Pellgunoil on the tip of the next CO2 cartridge to stop this leak. You should be oiling every new cartridge that you pierce.

  72. Hello, i got a Crosman 31, and it leaks from the pipe not very much but it sure leaks, i fixed the leak from the patron, juste used som regular oil lol O.o, but i don't know about the leak in pipe? plz help me


  73. Filip,

    I'm not sure what you mean when you say the "pipe." Are you referring to the barrel?

    Oiling the gun may not fix all leaks, but you should try this. Put more oil (Crosman Pellgunoil or 20-weight motor oil) in where the CO2 cartridge is pierced, then pierce a fresh cartridge. Now, shoot the gun without BBs several times (20 or so) very fast. That will blow the oil through the valve and let it get on every surface. If oil is going to stop the internal leak, this is the way to do it.

  74. Hey, my friend gave me a 303 BB pistol and i use it shot fine then i took off the cover bymistake and i put it back toghther then i put a co2 bottle and while am closing it it keeps leaking a dint shoot no more after 8 seconds…. Idk wats wrong but it runs out of co2 quick and cant barley fire


  75. I don't know what a 303 BB pistol is. Is it an airsoft gun? If so I'm afraid we can't help you here.

    Is it a pistol that shoots steel BBs? If so, who made it, or what company's name is on the gun?

    What do you mean by "the cover?" Are you referring to a part of the pistol such as the slide, or do you mean the place where the CO2 cartridge is installed?

    I assume that you have already tried the remedy recommended in this posting?

  76. This got deleted by mistake.

    Hello.
    I got my Crosman 38t from my grandfather, and the first time I put a CO2 cartridge all gas leaked realy fast (+/-5 seconds). This is my first airgun and I don't know what to do. I tried applying pellgunoil, left it for a night, and in the morning I tried putting CO2 cartridge again and it also failed.
    If anyone can help me somehow I would be really thankful.
