The heart of the Zurn PEX Plumbing System is its flexible and strong PEX tubing. It has a service life of more than 100 years and pressure ratings up to 80 psi at 200 degrees F and 100 psi at 180 degrees F. Zurn uses its QickSert I insert and crimp fitting system, and offers a 25-year warranty on tubing and fittings.
