Will sharkbite work on PEX AL PEX?
Also question is, do SharkBite fittings work with PEX?
SharkBite Universal brass push-to-connect fittings are compatible with PEX, Copper, CPVC, PE-RT and HDPE pipe. SharkBite fittings come with a PEX stiffener pre-loaded into the fitting for PEX, PE-RT and HDPE. The PEX stiffener does not need to be removed for Copper or CPVC applications.
Accordingly, which is better PEX or SharkBite?
