Hey guys. Just bought a new valve for the fx bottles from fx. Is like $50 plus $9 shipping. They are limited so they said only 1 per customer. Go get one b4 they run out if you want one. Anyway, do I need to use locktite when installing on the bottle or no? I dont want it unscrew when trying to take the bottle off. Or the pressure would prevent it from unscrewing when taking off from the gun?
