Valve Porblem. Please look.

[Benfica4ever]

every time i turn the on/off vavle in my antisiphend c02 tank It leaks from right were the velocity is. I dont know whats wrong with it. Its a Ans PHase 2 air valve . i dont know if i need a new o-ring or a reg piston, should i just send it to my local paintball shop, or should i just buy the part?But remember its a ANS PHASE 2 AIR VALVE
please help me out.

take out the velocity screw, remove the spring pack, and remove the reg piston

put a new o-ring on the reg piston

oil the o-ring

grease the spring pack with a coating of white lithium grease (only use this grease)

re-assemble valve and gas it up


if it still leaks, you have a bad reg piston, if it doesnt leak, then you just fixed your problem


you'll also want to check to see that your anti-siphon tube is pointing upwards so that it doesnt suck co2 into the gun

it was matched to a certain ASA, if you are using a different ASA, then there is a very high possibility of the start of the threads being at a different location, so that the tank will be sitting in a different position than the anti-siphon was installed for

Thanks for letting me know about the asa thing. But i am still using the same asa.
