Uponor PEX plumbing systems feature a flexible, durable plastic piping product called crosslinked polyethylene (PEX) piping instead of metal piping to distribute the water. Uponor PEX piping is a proven product with 40 years of history in radiant heating, plumbing and fire sprinkler systems. It is a clean, non-toxic and extremely durable piping product that will not pit, scale or corrode and even helps resist freeze damage.
An Uponor PEX plumbing system is a clean, healthy, quiet and reliable system that provides numerous benefits over a copper or CPVC system, including corrosion resistance, better freeze resistance, fewer connections for fewer potential leak points and a 25-year limited warranty.
Uponor AquaPEX® piping for potable (drinking) water is held to the highest testing, codes, listings and standards in the plumbing industry. In addition to testing and certification at NSF International, Canadian Standards Association (CSA) and Underwriters Laboratories (UL), Uponor PEX piping has been tested and approved for potable-water applications by the most demanding agencies in the world, including DVWG-Germany, KIWA-Netherlands, CTSB-France and BSI-Great Britain. Toxicity extraction testing performed in accordance with ANSI/NSF 61 “Drinking Water System Components – Health Effects” verifies Uponor PEX piping does not leach potentially harmful substances into the drinking water.
Uponor PEX piping has several benefits over copper pipe. Because of its flexibility, Uponor PEX can bend with each change in direction. This means fewer connections are required, which, in turn, means fewer potential leak points. This flexibility also enables it to expand up to three times the piping’s diameter, which means it is more resistant to damage from frozen water in the system.
Uponor PEX conforms to the following listings. Be sure to visit the listing agency’s website for complete details.

Uponor PEX meets the following codes:
- NPC of Canada

ASTM F876, the Standard Specification for Crosslinked Polyethylene (PEX) Piping, was revised in August 2008 to include a voluntary oxidative resistance (i.e., chlorine resistance) rating that indicates suitability for use in continuous-recirculation systems where piping is exposed to hot, chlorinated water 100 percent of the time. Uponor AquaPEX® piping for potable-water applications is certified by NSF International to meet the latest ASTM F876 oxidative-resistance requirements for continuous recirculation, as indicated by the PEX 5106 designation on white piping and PEX 5206 on red and blue piping.
