Guest Blog: Maximize Hybrid Piping Systems with new PEX Expansion and Copper Press Transitions

Share With:

Two piping systems that are taking the domestic-water and hydronic heating and cooling landscape to a new level. These innovative solutions are providing the construction industry with systems that are easier to learn (to help with the skilled-labor shortage), faster to install (to meet tight construction schedules) and provide cleaner installation sites (for jobsite safety).

For PEX pipe, popularity is growing for risers, distribution piping and even direct-burial applications in sizes 3″ and down. Its flexibility, fast installations and stable pricing make it appealing for contractors, and its corrosion resistance and durability in freezing conditions make it highly attractive to building owners.

For copper press, contractors are enjoying a safer, flameless connection system that eliminates solder, heat and flux from the job site while offering contractors a metallic system that is faster and easier to learn and quicker to install.

Now, imagine combining the best of both worlds — PEX expansion and copper press — for quicker, easier training, faster installs and safer jobsites to get the job done right in less time.

With the launch of the industry’s first ProPEX® expansion to copper press transitions, professionals now have a solution for a completely flameless piping system that eliminates the hassles, costs and hazards of soldering while also providing more efficient installs.

Watch how easy it is to make these transitions.

Manufactured from high-quality, lead-free brass to meet all local and national domestic-water building codes, the transitions are available in both male and female configurations with the female adapters featuring an EPDM rubber O-ring for a dependable seal.

Best of all, they feature a patented design for securely fastening the pipe and fitting together, eliminating the need for a stainless-steel ring commonly used in large-dimension copper press fittings.

Compared to soldering copper, these transitions reduce an overall project timeline by an average of 71%, helping to manage a project’s schedule and, ultimately, the bottom line. And because they are backed by a 25-year transferable limited warranty, the transitions offer additional confidence and peace of mind.

So if you’re like most construction professionals out there, feeling the crunch of the labor shortage but still want the quality of a professional piping system, look to a hybrid PEX expansion and copper press system. The end result can be money in the bank.
