Milwaukee® Develops M12 FUEL™ ProPEX® Expander in Partnership with Uponor

MILWAUKEE, WI- Milwaukee Tool and Uponor® have partnered once again to deliver another game-changing solution for ProPEX® installs with the introduction of the M12 FUEL™

ProPEX® Expander. Equipped with RAPID SEAL™ heads to seal up to 65% faster than competitive solutions at 45º, the new tool will be part of a complete solution to provide the industry’s most consistent installations.


“In 2010, Milwaukee® & Uponor® changed the way plumbing and mechanical contractors installed ProPEX® fittings with the introduction of the M12™ ProPEX® Expander.  This tool set the new standard for productivity, delivering faster and more consistent installations by eliminating the need for cumbersome hand tools. Ten years later, we are excited to once again partner with Uponor®, to deliver the next breakthrough in productivity for ProPEX® installs,” said Morgan Sokany, Senior Product Manager for Milwaukee Tool. “With the introduction of the new M12 FUEL™* ProPEX® Expander, installers can expect the fastest 3/8”1” expansions and decreased seal times especially as temperatures decrease, all while maintaining the promise of the most consistent installations.” 

Providing up to 35% faster connections, the ProPEX® Expander features a POWERSTATE™ Brushless Motor, delivering sustained peak power even under the toughestconditions, and an extended dual-actuating trigger for better access in tough to reach workspaces. The expander will come standard with the new ProPEX® Expander Heads with RAPID SEAL™, designed to provide faster sealing connections in colder temperatures while maintaining the expected time to insert a fitting. Like its M12™ predecessor, the M12 FUEL™ ProPEX® Expander is equipped with an auto-rotating head for quick, uniform expansions and built-in LED lights allow for convenient operation. 

The new M12 FUEL™ ProPEX® Expander joins the M12™ Cordless System, the largest sub-compact system on the market, focused on delivering industry-leading durability and power in the tightest spaces. Currently the M12™ System is made up of more than 100 solutions. 

*M12 FUEL™ power tools are designed, engineered, and built to deliver extreme performance and productivity. All M12 FUEL™ products feature three Milwaukee®-exclusive innovations— the POWERSTATE™ Brushless Motor, REDLITHIUM™ Battery Pack and REDLINK PLUS™ Intelligence Hardware and Software—that deliver unmatched power, run-time and durability on the jobsite. Simply put, M12 FUEL™ tools are the most powerful sub-compact cordless tools in their class.
