PEX Crimp Fittings

PEX crimp fittings are the standard type of fitting used in PEX systems. A large variety of fittings are available to make PEX-to-PEX connections, as well as transitions to other pipe materials.

Most crimp fittings are made of brass , but poly-alloy crimp fittings are also available.

Crimp fittings require copper or stainless steel crimp rings and a PEX crimp or clamp tool. Some manufacturers use O-rings on their metal fittings to make the seal with the tubing.

Crimp fittings are compatible with all types of PEX tubing, except for PEX-AL-PEX. Crimp fittings are preferred for many applications since they are widely available and are the most affordable.
