“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.”
“These crimp well and seal PEX B fittings as they should. However, they are initially looser on the pipe than the ones made by Apollo and Sharkbite, which are pretty snug when sliding them onto PEX B pipe. I don't know if that makes any difference, but they seem to seal OK.”
