Why is PEX Better Than Rigid Systems?

Ask anyone who has installed an Uponor PEX plumbing system. Once you experience the faster installs, the reduced liability and the stable material costs, you’ll be a believer.


Because of its flexibility, Uponor PEX can bend with each change in direction, which means fewer connections, faster installs and reduced potential leak-point liability. The flexibility of PEX also enables it to expand up to three times the tubing’s diameter, making it more freeze-damage resistant.


With an Uponor PEX plumbing system that features ProPEX® expansion fittings, dry fitting is never a concern. That’s because you can’t dry fit an expansion fitting. The PEX tubing and ProPEX expansion ring must first be expanded before the larger-diameter fitting is inserted. As the PEX shrinks back around the fitting, it creates a strong, durable connection that holds tight with 1,000 pounds of radial force.


PEX is also highly corrosion resistant, so it doesn’t have the issue of pinhole leaks or corrosion build up like copper. And PEX is also safer than copper. A study done by Rochester Medical Center published in Proceedings of the National Academy of Sciences reported a connection between copper and Alzheimer’s disease.
