Forum Title: Pex Crimp Ring Tightness
I am building a bathroom in my shop and am using 1/2" PEX lines. I am using the barb fittings with the copper crimp ring. I have the proper crimp tool for this application, also the go/nogo gauge. My question is when you crimp the ring, should the fitting you crimp be able to rotate in the PEX pipe? My go/nogo gauge slide over my crimps half way and not all the way to the u part of the gauge, is this normal? Or should I try to tighten the crimp calibration some? Thanks, Scott

It is normal for the fitting to be able to turn inside of the ring after the ring is crimped.
