Just fitted an on off asa as per title. I have checked and rechecked to make sure the o ring between the two seems ok coiuldnt really tell where the leak was coming from.Im not sure if it relevant but the bottle i tested it on only had a couple of hundred psi in it so im not sure if that was the problem.
I couldnt tell there wasnt a lot of air in the bottle couple of hundred psi maybe i was wondering if there wasnt enough pressure to seal
Found a thread on minis asa took it off refitted as per guide seems much tighter and doesent seem to be leaking now i think foot posted it up thanks !!
