Zurn Pex or Seymour or neither

[Pitterpat]

The plumbing supplier I use most stocks Zurn and Seymour pex. Are either one of these ok or should I stay with Uphonor pex or maybe another brand?

There are three manufacturing techniques used to make pex called -A, -B, and -C. They have slightly different characteristics with -A being the most flexible (able to be bent into the smallest radius without kinking) and the only version that can be restored if it does get kinked (happens, not too often, but more often with a 'newbe DIY'er); the other types you must cut the kink out and install a fitting. So, they'll all work, but it depends. Uphonor is -A and is the only one I know of that also makes their own material as well as the tubing, so they have full quality control of the whole process. It also uses the expansion type fitting - the others use crimp rings. The expansion system allows the ID of the fitting to be (slightly) larger, decreasing restrictions and maximizing flow.
