Uponor PEX pipe and ProPEX® expansion fittings are now available in 2.5-in and 3-in sizes. The company says the new sizes offer professionals the ability to specify, design, and install even more commercial plumbing and hydronic piping systems with PEX. The pipe offering, which includes Uponor AquaPEX® for potable-plumbing applications and Wirsbo hePEX™ oxygen-barrier pipe for hydronic heating and cooling applications, is available in various coil lengths and straight lengths to meet any application need. The ProPEX ASTM F1960 expansion fitting offering includes a complete line of tees, elbows, couplings and transition fittings, as well as a flange adapter kit. The offering also includes new PEX pipe cutting tools and larger sizes of PEX-a Pipe Support (a steel channel that enables hanger spacing similar to that of copper for suspended-piping applications).
