Milwaukee and Uponor Team Up To Change the ProPEX Game

Milwaukee Tool and Uponor have partnered up again to improve the consistency of ProPex installations. The Milwaukee M12 Fuel ProPEX Expander, due out in December, ups the ante with a brushless motor. It also includes three different Rapid Seal heads to cover 1/2″ through 1″ PEX. The new heads seal up to 65% faster than competitive solutions at 45º.

Key Features

Milwaukee M12 FUEL ProPEX Expander

The Milwaukee M12 Fuel ProPEX Expander features a brushless motor that delivers more power, speed, and runtime than the Milwaukee 2432-20 ProPEX installation tool even under the toughest conditions. Milwaukee claims that it even provides up to 25% faster connections.

It also comes standard with three new ProPEX Expander Heads with Rapid Seal. Milwaukee and Uponor have designed these heads to provide quick fitting installation and faster sealing connections in colder temperatures.

The Milwaukee M12 ProPEX Expander features an extended dual-actuating trigger for better access in hard-to-reach areas. It also comes with an auto-rotating head for quick and uniform expansions. You also get a built-in LED light—something we almost take for granted now on the newest cordless tools.

Notable Improvements

Clearly the new ProPEX Expander Heads with Rapid Seal and brushless M12 FUEL motor top the charts on what’s new here. We also can’t help but note the handy belt hook—we always like seeing those. We look forward to getting this tool into the hands of one of our Pro plumbers to see the improvements over the former M12 model. We’d expect reasonable speed improvements and certainly more run-time. In the end—this looks like a great indicator that Milwaukee remains committed to maintaining and expanding its hold on the world of cordless PEX plumbing tools.
