25-Pack of Captain O-Ring Paintball Remote Quick Disconnect & Fill Station Orings Review

Air hose fittings require 0-rings to seal properly. They do their job. You will need a set of picks to get the old o-ring out.

I ordered these o-rings because I had an air leak from a pair of my inlet fittings. I used the o-ring from the captain's o-ring kit and there was no more air leak.

I have a 4500psi HPA Air Venturi compressor that I use to vent my 66 cu ft carbon fiber SCBA tank (I use the tank to refill my PCP airguns ). Well, the Foster fitting at the end of the compressor's fill hole started to lose air and I couldn't fill the tank anymore. So I ordered this pack of O-rings. I removed the old, damaged o-ring from the Foster female fitting at the end of the compressor fill port and put in one of these new ones, connected the fill port to my air tank and it worked great…
