View Full Version : Valve Polishing

I did a leak test on my gun after all the mods I did, the only one I found was a slight leak at the valve...

Took it out and got to looking at the face that the plunger sits on and seen slight marks that "may" have been the leak, I know the plastic plunger can deform a little to these but if it rotates a little the it would have to reform...

I took a diamond knife sharping stones and carefully turned it by hand so not to make the face angled, went fine'r until it shines like chrome, put in the replacement plunger and pressure tested under water, no more bubbles.

So if you have a leaky valve take it out and check the surface for nicks and stuff.

Just a tip from your local crip !
