![]() “Because the outside surface of Uponor PEX is depleted of antioxidants after the flame treatment, the outside surface prematurely becomes brittle and develops microcracks when the tubing is expanded during installation,” the lawsuit elaborates, claiming the tiny cracks stemming from the manufacturing defect can grow and eventually cause leaks and significant property damage. This heat treatment, however, destroys the tubing’s antioxidant stabilizers, which are crucial for the piping to achieve flexibility, maintain ductility and protect against embrittlement, the lawsuit says. According to the complaint, Uponor, in order to get the blue and red coating to stick to the outside of the PEX tubing, runs the product through a furnace/flame treatment that aids in the application of coatings and adhesives. The 20-page lawsuit out of Colorado claims the Uponor PEX piping, a popular product made for use in residential plumbing systems, can develop exterior microcracks due to the oxidizing process whereby the blue and red coloring-for cold and hot water lines, respectively-are added to the tubing. *To download a hi-res image file, click the Hi-Res image link, right click the larger image, and select save image, to save to your local computer.New to ?
