Do you have piston seal for model Cz slavia 631
No. Try Air Rifle Headquarters.
Would this piston seal work for Hatsan Torpedo 155 Vortex.
No. For parts you havevto contact Hatsan USA.
Will this seal fit a Benjamin Trail XL1200? Thank you
This fits all the XL guns and is vastly superior to the oem seal. When you remove the oem seal note the damage to the delicate sealing edge. This happened during install at the factory thanks to the sharp edges along the trigger and cocking slots. You need to smooth all these out before installing this nice new seal. I use a Dremel with a diamond bit, but you can also use sandpaper. I simply wrap sandpaper around something like a popsicle stick or dowel to make a sanding tool shaped right for the job. I have info on all the above and much more stuff you can do to these guns if you/anyone want it. chevota at hotmail, tell what gun/caliber you have and I'll send it.
Will this work for the Vortex gas piston in the hatsan 125 vortex?
I have opened my Hatsan 125 and it seems as if the seal is rock hard. It was very difficult to cock and firing was 'erratic'. The piston was very tight in the chamber and I had to use a hammer to ease it out. But I cannot see any metal on metal chaffing marks. If the rifle was left in the direct sun could the seal have become rock hard?
The sun/heat no doubt dries and hardens a seal sooner, but my guess is that would take a looong time. The oem seal is just low quality. My oem Hatsan seals, including 125, are no doubt the hardest seals I've ever removed from a gun. I have a used 125 seal and this new red one in my hands as I write this, and while the red seal is a hard for an aftermarket, it's much softer than the oem. Plus it's a better material so I'd bet $ it'll still be softer after 20 years. Seems like polyurethane to me but who knows. Note the damage to the oem seal caused by the sharp edges in the tube cutouts. Smooth those before installing this new seal!
Is this seal fits gamo hunter 1250
The 125 seal fits the Trail XL, and since the 1250 and XL are very much the same I'd assume yes. The OD of this seal (new) on the top/bottom is ~1.145"/1.105, and ID ~.614"/.578". An oem XL seal (new) is ~1.165/1.040 ~.660/.520. Thickness of each is ~.260". So the dimensions looks like it's a no-go, and the Walther seal is not actually tapered on the inside, but stepped, yet it works perfectly on the tapered dovetail of the XL. So my guess is if your dovetail is ~.630" wide and ~.230" tall, I'd say yes... If your dove is much wider, like .750", then I'm betting the NP2 seal (CRS5177-012) will fit.
Is this the proper seal for a Walther FH with Crosman nitro piston?
Yes, the seal fit the Walther FH regardless of what spring you have.
Will this seal fit the Benjamin Trail NP XL?
Yes, this seal is far better for trail xl than factory one!
It says Hatsan 125. Both the Vortex AND the Springer? I have the springer.
Yes it fits the springer
Will this fit the new crosman np2 airrifle?
No, you need # CRS5177-012, which is Pyramid # Crosman Piston Seal, Fits NPSS,.... Pyramid doesn't mention that it fits the NP2 but that's it...
can PA install this at the same time they install the Nitro Piston upgrade on a WFH?
I don't believe PA actually does the install, I think it's a third party. Either way I doubt they'd install it without damaging it so I would only change the seal myself/yourself. The problem is the guns have sharp edges inside so really you need to file and/or sand those smooth in order to safely install it. If you're willing to take the gun apart I have instructions on how, which I can send you. Just ask; chevota at hotmail. Also have the option to skip the nitro and make the coil spring work well enough that you probably can't tell it's not a nitro, which doesn't cost anything, just some time.
will this fit the Hatsan 155?
I don't know the specs on the 155 but I can all but guarantee this is not it. Yours probably takes the same seal as an 85 or similar size models. The 125 is a magnum so it's bigger.
how do i change my piston seal on Hatsan 125th??
The actual removal and install of the seals is easy, but you have to take the gun apart to get to it. Youtube has lots of vids of people taking break barrel guns apart to give you an idea. I think it's pretty easy and don't use any special tools but for a first timer it looks intimidating. Also be careful not to tear up the new seal on the sharp edges in the gun, which the oem seal will usually bear witness. So either smooth said edges or be super careful installing.
Does this work in umarex octane? Thanks in advance.
No, use a seal for a Diana 350 which are pretty easy to find.
Will this fit umarex octane? Thanks in advance.
What is the diameter of this seal? 1" or 1 1/8 ?
It's 1.145", it's meant to fit a 29mm bore. It's a very well designed seal of top quality. It also works perfectly on the Benjamin Trail XL, much better than the oem seal.
It is just over 1 1/8"
Will this also work for the Hatsan mod135? Ive heard that some parts are slightly different than the Hatsan mod125
This part will not fit the 135 as it is larger.
i have the same will these seals work with the 125 sniper vortex?
Yes the seal is the same.
Does this work with the Vortex or Nitro Piston versions?
It will work on both versions
