I would like to know that as well. I feel another fitter/ boiler maker favour coming upOoooooh what a beauty! Never seen that gem before. I have never had trouble with the plastic stop. I make sure to thread it all the way in from the first day. Threads were tight at first but now I can spin it almost all the way by hand. Finish with a box wrench 11/16. I use the impulse for the pressure/vac test but rarely need to do them. Mostly to check the 045 bearings with integrated seals.
Pogo where did you find that gem?
