Benjamin 300-DIN Male Adapter, Fill Adapter, Fits Benjamin Carbon Fiber Tanks

Excellent build quality and value for the money

Nothing

This is a very high quality piece of gear. Screws right into a carbon fiber tank, and it is very compact. More so than the images suggest

this adapter fit and worked as stated, easy to install and simple to workin

include an 90 deg. elbow to prevent connection problems that come and go

always keep a spare stached away

It works at adapting the Air Venturi compressor to our DIN valve on our tanks.

Provide a better plastic sleeve to protect the threads. The one sent doesn't work.

Too expensive.

I needed this to fill my BenJi Carbon fiber tank. I had only one problem. When fiiling the tank the adapter was leaking a little and tightening it didn't do anything. So I let it leak a little and filled my tank to 4500PSI with a extra 4 mins time. Once the tank was full I pulled it apart with two wrenches. Now they make 3 teflon thread tape. One is white and one is dark gray. The difference is the dark gray is thicker and use on this adapter. Which one or two wraps is fine. Using the white teflon tape maybe 3-4 wraps. The third I don't talk about is used for LP Gas. So White is .97 cents and dark gray 2.00$ home depot. My adapter was 100% as pictured. As for the leak it wasn't a big deal to bring to anyone's attention.

I would test if leaks before shipping. Very simple, As some people could be clueless what to do. All in all worth the money and works as it say's. I may just change the foster valve with a one way foster valve. This valve just a standard. This way the foster valve you just wouldn't have to close the tank and just let the pressure release from the tanks bleed valve or the compressor. But all in all once you remove the adapter you better close the tanks valve first

But this is for your Benji tank and you own your compressor it's great. Scuba shops your lucky up to 3600-3800PSI on a good day and when tank cools your pressure drop 200PSI...And where i'm at paint ball shops open only Saturday and Sunday. And they charge for each 1000PSI.

works great with pistol air tanks

should have better protective sleeves on unit

Works great

Would be nice if it was shorter be still good

No pressure loss, easy to affix to my "buddy bottle" and accomodates the "marriage" between my Benjamin Buddy Bottle to my Omega Super Charger well, (Omega Super Charger is from Airguns of Arizona).

Nothing, it works great.

The "Foster Fitting" is steel, not stainless steel, but I have no problems with it. I keep it lubricated with lithium spray and find it doesn't rust. Fits well with all my charging hoses.

can now fill small scuba bottles from ben pump and transfer from my 80 cf scuba tank to my 6 cf pony bottle super and a must have

not a thing

to check pressure in your 3000# scuba tank connect benjerman pump then pump up to to 3200 psi (5 to 8 pumps ) and gentle open scuba tank and watch pressure gauge on pump what it falls to is pressure in your tank close tank and bled off hose pressure and disconnect

It makes changing from filling my tank to charging up my guns easy.

The unit that I received did not have a finger knob as shown.

Very handy you will like it.

works great to adapt the din hole on my hand pump to work with the Air Venturi hose to fill my synrod. Threads on the adapter cut nicely, screws in smooth by hand.

maybe make this from stainless steel. I think for the price of this that should be do-able.
