On my propress pro flow jaws for viega pex, sometimes the fitting after being crimped has a little ridge on it that you can feel with your finger, as I look at the jaws (which are new) I notice all of them have movement up and down where they meet at the top which makes the ridge I am speaking of. I also have the generic pex jaws that do zurn or any other crimp ring style pex and they seem solid and don't leave the little ridge on them. My copper jaws don't do this either. Any Ideas? Or is this just normal?
