I was gifted a piar of old model Norgren regulators. The two are ganged together by a brass nipple which has, over the years, siezed up tighter that a guy getting a proctal exam.
I have tried heat with a propane torch, WD-40, heat then WD-40, cleaning with vinegar, and all manner of wrenches with it mounted in a vise.
The union has now been rounded over from all the wrenching and the only thing that can get a bite on it is a vise-lock wrench but, even that spins eventually. The danged nipple won't budge.
Any suggestion on how to separate this thing?
