Well I just got my promaster today from a guy off pbn. When I first aired it up the needle on the guage showed way past 600 psi. So I degassed it.

I figured it was the regulator so I backed it out a bit and still the same thing without any improvement pressure wise.

I gave the reg a good lubing and that didn't appear to help at all either. All the o-rings looked to be in good condition also.

Btw, i'm using a hp crossfire tank. Hopefully this will be an easy fix.

Thanks for any help.

replace the o-ring on the hpr piston. It's messed up. Also, could you tell me if you have 1 or 2 o-rings on the piston?

I'll see if that helps at all.

And it has 2 o-rings.
