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

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 again - and still does. happen again this time, but I'm ready.
