I don't expect there to be any added stress on the valve, but there's no problem with the set-screw. I messed up another tube testing my SS screw in the HiFlo valve. The old GEN1 with the hex nut on top was perfect for wrenching the HiPAC in until it bottomed out against the tube. I didn't get a torque wrench reading. They said that that's no way to test the shear strength but don't remember which idiot said it, but it wasn't Bob. It deformed the backside of the set-screw hole in the tube and but the screw didn't give way. I'm guessing it'll work as well in the other direction. Right now the only difference is that mine is heavier, lol. I haven't taken my gun apart to test it. Guess I could put one of my other ones back together. I'm also considering making it adjustable for weight. I got that figured out too. That would really change things. I'm still waiting for the HiPAC to vanish ("dang" a slow leak) and fill the tube with 3Kpsi and explode. He said it would so it must be true...since he said it.
