Airforce Parts for Airforce air tanks

I have been able to obtain parts for my Texan from Airforce, but I was wondering if the quick connect valves on these are available from other sources. These valves have a habit of leaking when you want to use a rifle. I have searched the normal air gun vendors but except for the whole bottle, parts cannot be found. Has anyone located a source for these?

Are you talking about the foster fitting? I’m unaware of any leaking issues on Airforce airguns. None of mine have any leaking issues.

I am ashamed to have posted this question. You are right, the Airforce guns I have do not generally have leaking Foster fittings. When I did not shoot my .357 for quite a while corrosion formed in the fitting. When I removed it the o ring was gone and I tried to get it to seal forgetting about it needing an o ring. I really like the fact that Airforce is made in the USA and uses only American parts. Their simple design makes them easy to maintain unless you are plagued ny brain farts. Like the one I had. I also have the Texan .457,357, and Condor .25.
