Correct Process for Installing a Valve on a SCBA Tank

[PelletJunkie]

I am trying to figure out the correct process for installing my JB TJ3 valve on my new Acecare Carbon SCBA tank. Is there an installation protocol that is recommended or anything that should be put on the threads (grease, teflon tape, etc)? Also how tight does the valve need to be put onto the Carbon tank? Any assistance is greatly appreciated.

I have purchased a 9L air tank similar to this item https://www.ebay.com/itm/2334386003...fWpHJapx7wbmbl0g79KBpCG4k=|tkp:Bk9SR5COpLPwYQ
When I received it I just put a small 100% silicone oil on the o-ring then just hand tightened it. Its been holding 300 bars of pressure since I purchased it new back in November of last year.

Exactly what charlie99 said.

Ditto to what charlie99 said.
To add a little. When I was trained in Chicago for inspecting high pressure vessels we were told to just put enough silicone grease on the O ring to make it shiny, not gobs of it. We also put a small amount on the male threads of the valve to prevent galvanic corrosion. But if your tank and valve are both aluminum alloy, that’s not necessary but can’t hurt if you do it anyway. Just a light film coating.

Thanks for the responses. It dawned on me that I should call Joe at Topgun Airguns and see how they install the valves and it was the same thing as shared above. A little silicone oil or silicone grease on the o-ring, thread the valve on (no lube or anti-seize on the threads) hand tight and that is it.

I'm going to fill the tank tomorrow.

Hand tight. The 4500 psi will keep it firmly in place.

to all the above! No need to over tighten. Screw that sucker in & you should be good to go.
