I have a Gen 1 Umarex Gauntlet with OE Ninja bottle and 3000psi standard regulator. The regulator bonnet was originally a ball type. That was fine for several years, but eventually I started having leakage issues at the ball, and given that it seems this has since been replaced with a pin type bonnet, I found an upgrade kit and installed it. With the bottle fully pressurized and dismounted, the assembly is absolutely pressure stable and free of leaks. All good.
The issue is manifested only when the bottle is screwed completely and securely into the air block. For example, I pressurized the bottle to 2000psi this morning, and it has already leaked to 1500. I changed the two orings at the tip, but it's made no difference. The only thing I've not done is make a wrap of teflon tape on the bonnet threads, but to me this seems like a questionable exercise. The seepage is clearly through the block threads (I can just barely hear the leak), and I'm not sure what else to do. Any experienced suggestions are welcome.
