EcoPoly PSU insert PEX fittings meet cNSF-14 Annex G for Lead Free 61, and are manufactured to ASTM F2159 F 877 and CSA 137.5 specifications, making them ideal for professional installation or do it yourself plumbing repair.
Compatible with copper PEX crimp rings, stainless steel PEX clamps, and any brand or type of SDR-9 PEX tubing, EcoPoly PSU insert PEX fittings require the use of a copper ring PEX crimper or stainless steel clamp PEX crimper.
To install, cut the PEX tubing square, slide a copper ring or stainless steel clamp along the tubing, insert the barbed fitting into the end of the tubing, slide the ring over the barb so it is about 1/8” from the body of the fitting, and crimp the ring/clamp with the PEX crimper.
Rings and clamps are sold separately unless specified in the description.
Constructed of durable Udel Polysulfone (PSU) resin, EcoPoly PSU insert PEX fittings are made from a resilient plastic resin that is resistant to stress fractures and extreme temperatures.
However, PSU is susceptible to Volatile Organic Compounds (VOCs) such as bug spray, certain cleaners, pipe dope, primers, glues, and adhesives, so keep all products made of PSU out of contact with VOCs.
