“i ordered these to run plumbing on my Off-Grid Cabin. did since test crimps on pieces i had available and they are working great so far. These will easily cover my needs and leave me plenty of spares should a couple ever leak, and for future projects.”
“So they are really loose on the pipe, but they tighten down fine with my ryobi pinch clamp tool. No leaks out of the few I've installed in my well house. Pex is nice because if it's not leaking now, it's highly unlikely to leak later. I still recommend sticking with the same brand for the rings and tubing/fittings. Better warranty that way.”
