@bat54action A SCBA tank is a Self Contained Breathing Apparatus tank. That's what you have in the second photo, a carbon fiber SCBA tank. It appears that you are in search of a SCBA tank valve or valve component like a gauge that displays the pressure level. I don't see a regulator in your photos.
www.topgun-airguns.com You're correct! I didn't realize the difference, but I do now. Yes, what I am looking for is the "valve", which is the part that screws into the tank. Also, I was able to disasemble the valve in the way that you stated. I found two O rings and a teflon ring I believe, along with a seal at the base of the hex I unscrewed. Nothing seemed to be out of place, or bad. Nothing like a cut ring. I cleaned everything up and it's now in the process of charging the tank. Last time it seemed to charge just fine up to 3000 PSI. I think its time to just purchase a new valve and be done with it, which I'm going to do. I have found a couple thanks to the members on here. Plus it will be a few days or so before the new one arrives. I really like the Saber Tactical that Utah Air has, but again the price is a bit stiff, but the carry handle on it would be a nice addition.
