cup seal?

[universepb]

on the manual for the pt extreme it says that if the co2 is leaking through the barrel (which mine is) there was a problem with the "cup seal"
i bought a delta 68 parts kit, took apart the entire gun, all the way to the valve, replaced every part i could (the only ones i didnt use was the one with the blue thing on the end, and the silver thing that screws into something)
i dont have any spare 12grams on me, should it work now, or did i not fix the problem with the "cup seal"

The Cupseal is inside the valve assembly. The cupseal you got with the delta kit will not fit the PT Extreme. The Pt Extreme has a one piece valve, but can be taken apart of service. If you need parts or repair, call Paintball Solutions for help.
