Remove with grips and I use a drop of sealing compound. when screwing in the new valve.

Also I can't screw my Trevor regulator onto my on/off valve! When I try to screw it in the thread on the valve can't reach the thread on the regulator, do other people have this problem?
The Trevor regulator isn't supposed to fit a paintball valve ...the threads are different between a paintball and European CO2 cylinder.
