I was surprised to learn yesterday that not all PEX tubing is the same. There are several types, each manufactured differently, giving each type different characteristics.
Here's a spec on PEX-b that describes compatibility of various fittings, with PEX-b.

Here's a spec on PEX-b that describes compatibility of various fittings, with PEX-b.
Everhot 1/2" PEX Tubing is PEX-B tubing and can be installed using either Crimp type connection system (Crimp Tool, Crimp-style PEX Fittings and Copper Crimp Rings) or Clamp/Cinch type connection system (Clamp Tool, Crimp-style PEX Fittings and Stainless Steel Clamps). Also compatible with Push-Fit connection system (such as SharkBite), Viega Press type system and Compression type PEX fittings.
