PEX Fittings

PEX barb and expansion fittings, couplings, elbows, tees, adapters and valves in brass and poly alloy.

PEX fittings and valves: barb and expansion (PEX-A) fittings in brass and poly alloy, couplings, elbows, tees, straight adapters, stop and ball valves, test plugs and pinch clamp tools.

Barb and expansion systems are not interchangeable — barb uses a crimp ring or pinch clamp, expansion relies on the tubing shrinking back onto the fitting, and each needs its own tool. Check which system the run is built on before ordering.

Brands include SharkBite, Apollo, Flair-It and Pexlock, including SharkBite crimp and push-fit ball valves.
