mixing brands of pipe with manifolds

SDSUBOB81 Member Posts: 1
So I go to Menards to buy the parts to install radiant in my new shop. Problem is that they don't have all the same vendor for the three pieces I'm looking for...pipe, manifold and pressure tester.... they sell Nucor pipe, Watts Stainless Steel manifolds (DIN Specs) and a Watts pressure tester which doesn't fit the DIN manifold........ Okay figured out the issue with the manifold...but my big question is can the Watts SS manifold work with the Nucor barrier Durapex pipe?

    If the pipe is SDR-9 and so is the manifold you should be fine. Don't use fittings with compression rings or sleeves that were not designed for those fittings. But if it's an SDR-9 fitting and SDR-9 pipe the brands don't have to be the same. (in my opinion)
