ASTM WIPEX Fitting
Extensively used in North America and Europe, WIPEX fittings are manufactured from dezincification-resistant (DZR) brass, and are specifically designed for connecting 1" to 4" Uponor PEX tubing. The WIPEX fitting features an eccentric outer sleeve — for easier grip and an even force when inserting the tubing — and an inner sleeve with a threaded profile and O-ring to ensure a secure, tight seal.
To create a WIPEX fitting, first chamfer the inside of the tubing with a chamfering tool, then use a pair of pliers to dismount the outer sleeve and place it on the tubing. Next, mount the tubing on the inner sleeve and tighten the fitting with a wrench. For complete instructions, refer to the WIPEX Fittings Instruction Sheet or view the WIPEX Fittings Video.
