When it comes to piping, PEX tubing, available in sizes from ¼" to 3", is the most flexible, durable, sustainable and cost-effective choice for any home or commercial building. Compared to installations that use copper, CPVC, and PEX crimp, Uponor PEX with ProPEX® expansion fittings offers the most efficient installation—saving time and money. Just see for yourself in this quick video.


Why is PEX a better product? Let’s break it down.


It’s flexible.

PEX tubing offers the tightest bend radius of any plumbing product on the market, eliminating the need for all those extra fittings and connections with each change of direction. For example, CPVC’s bend radius for a ½" pipe is a whopping 18", where as PEX’s bend radius is as tight as 3½".


It’s durable.

PEX requires up to 40% fewer fittings meaning less liability of leaks, like pinhole leaks often found in copper piping, and other fitting-related problems. When you do need to make a ProPEX connection with Uponor PEX, rest assured the process is simple (and even a little bit fun).


With Uponor ProPEX fitting systems, an expander tool expands a ProPEX Ring and the tubing to insert a fitting. Then the tubing and ring simply shrink around the fitting as they return to their original shape. And because Uponor ProPEX fittings cannot be dry fit, there is even less risk of leaks from unfinished connections like there is with CPVC pipes.


Best of all, because PEX can expand up to three times the tubing’s diameter without cracking, it’s also extremely resistant to freeze damage. Are you “oooing” and “ahhing” yet?


It’s sustainable.

During its lifetime, PEX-based systems have a lower energy content than copper-based systems. This is because the way copper is mined, refined and transformed into pipe products uses more energy than PEX piping.


It’s reliable.

With fewer fittings, fewer potential leak points, no risk of dry fits, no pinhole leaks, no corrosion buildup and greater freeze resistance, PEX gives you confidence you can’t get with any other piping material.
