Help with huma regulator flashpup

(1/2) > >>

JWL:
Got a new huma regulator for my flashpup synthetic. I can't seem to get it to seal up completely. I used method 2 of the venting methods. Getting a very slow leak from the vent groove. I lapped the valve screw bottom of the gun, that seemed to help but still not sealing up. I saw there is a very tiny scratch on the huma o ring gland. Not sure if that is the cause or how to fix it. Any ideas welcome.

triggerfest:
Probably just use some o-ring silicon lube and case closed.

Though the scratch on the o-ring is not a good sign and typically can't be solved by silicon lube only (ie safest way is to replace the o-ring and use the lube).

The scratch is on the regulator where the oring sits. It is very minor barely visible. I have tried silicone grease. The scratch might be from my oring hook pick

Got it.

I would take a picture and send it over per email to HUMA Air and ask them.

They are very knowledgeable and typically they are replying quite fast to queries.

clear nail polish will fix the scratch, I would apply, while wet, install o-ring, allow to dry, then lube the inner wall of the cylinder and o-ring with Silicone grease and install the regulator.
