Made of PVDF that’s finished to a 12 Ra smoothness, these fittings handle some of the harshest chemicals without leaching contaminants into your line. Comparable to Kynar, they handle most organic solvents that would dissolve CPVC, and chlorine or nitric acid that would weaken polypropylene.

Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push. An internal gripping ring holds the tubing tight.

Fittings have a sleeve that bites into tubing as you tighten the nut to form a seal in applications up to 120 psi. Also known as flareless fittings.
