Zurn Industries LLC has made available its 1 1/4- to 2-inch Zurn PEX Qick Sert CR Corrosion Resistant Polymer Fittings to meet large diameter applications. Customers now have a broad size-range—1/2 to 2 inches—from which to choose. The insert and crimp fitting system is constructed of a polymer material designed to prevent corrosion and resist chemicals and chlorine in aggressive water environments. It meets ASTM F877 performance requirements and reduces labor and installation time for PEX tubing. The crimp systems are immediately full strength upon installation and deliver more flow than required by fixtures. They provide a permanent, leak-free connection.
