Umarex PPK valve leaking

[Mudbugmitch]

I thought it was Only the seal for the cart. But after I get it back together, it fires once or twice then it starts leaking, slow at first then builds. Pull the trigger, it fires and then starts leaking again, slow then builds up.
I am thinking the valve.....


Thanks,
Mitch

I have no specific knowledge of the PPK but that behavior is typically what happens when a poppet with a soft seal is beginning to fail.

Thank you Jason.



This is what the valve looks like.The spring goes behind the washer. I can open and remove the parts to the right
 But not the right side. The green washer , maybe, ?

Hi Mitch, I don't have a PPK either, but I opened quite a few other Umarex CO2 pistols. My Ux Desert Eagle had the same symptoms as your PPK. It turned out there was a tiny particle on the green Oring causing the leak. These valves need to be ''squeaky clean'' to function properly, I just cleaned it carefully, re-assembled it with a generous amount of silicone oil on the seals, and Voilą! The ''old'' seals sealed again. HTH.

Thank you, happymechanic. I will tear into it again.
