What is PEXa?
REHAU began producing PEXa in 1967. When our company founder, Helmut Wagner, partnered with Dr. Thomas Engel to begin producing an alternative to traditional rigid piping systems. They were ahead of their time.
Today, we use the same process with decades of experience perfecting the craft as the basis pipe for our MUNICIPEX® family of products. Since we pioneered the flexible, crosslinked polyethylene we have been innovating ways to lead the industry in consistency. We back our product with a 25-year limited warranty.
Advantages over copper and HDPE
MUNICIPEX is a clean, cost-effective municipal piping alternative that surpasses many of the performance properties of copper and HDPE. Unlike other municipal lines that need frequent repairs or replacements, MUNICIPEX is not susceptible to corrosion and mineral buildup. It has freeze-break resistance properties, demonstrates impact and abrasion resistance, and has excellent resistance to chlorine and other chemicals.
