1/2" x 20 ft. hePEX Tubing, Straight Length

Uponor's Wirsbo hePEX straight length offering features all the benefits of the durable PEX-a pipe — cost-effective, corrosion-resistant, 25-year warranty — without retaining the inherent curve of coiled PEX pipe.

Uponor (Wirsbo) hePEX is heat-transfer tubing with an EVOH oxygen diffusion barrier. The oxygen diffusion barrier meets the requirements of the German DIN Standard 4726.
Uponor (Wirsbo) hePEX is compatible with both Uponor’s (Wirsbo) ProPEX fitting connections and QS-style fittings.
Uponor (Wirsbo) hePEX is manufactured to ASTM F876 and F877, and is designed for closed-loop hydronic heating applications. Uponor (Wirsbo) hePEX tubing is rated and listed by the Hydrostatic Stress Board of PPI at: 200 degrees F at 80 psi, 180 degrees F at 100 psi and 73.4 degrees F at 160 psi.
Note 1: 5/16" hePEX tubing is used for the Uponor (Wirsbo) Quik Trak system.

Note: Uponor (Wirsbo) hePEX tubing, traditionally used in radiant heating applications, became certified to NSF/ANSI Standard 61 for potable water in December 2012. Please read the Approvals document located in the Manuals tab for more information.
