This thread is killing me! I bought a used Pp700w 2 weeks ago. It was shipped to me in under a week but the seller forgot to include the fill probe. So while I waited and still waiting for it, I have read these 60+ pages all the way through. Twice! What really not worthy is that I had 4 days off work to play with it. Any one have an extra fill probe?
Hi.I would start at 120 bar, and see what you achieve with your particular gun and pellet choice.If you look at a posting I made a while ago https://www.gatewaytoairguns.org/GTA/index.php?topic=139000.msg1414294#msg1414294 you will see that I achieved about 9.5 ft-lb ME with my Huma at 120 bar. It is a good starting point for you, I think.I have always bought all my O-Rings at the O-Ring Store, and been very happy.I believe that the barrel breech o-ring is the 1.5mm x 9mm. But many people prefer the 90 durometer hardness.Have fun. These guns are so great, and the Huma makes them even better.Frank
