Our M12 FUEL™ ProPEX® Expander unlocks a breakthrough in productivity for plumbing installers, delivering the fastest 3/8”-1” expansions. Featuring an auto-rotating head, the expander provides you with uniform expansions for the most consistent installations. In combination with the ProPEX® Expander Heads with RAPID SEAL™, installers will experience up to 65% faster sealing of connections as temperatures decrease, reducing the time before pressure testing. An extended dual actuating trigger and a compact right-angle design provide you with easy access in tight locations. All-metal gears and an integrated metal frame deliver maximum durability on the job site. The POWERSTATE™ Brushless Motor offers the fastest expansions yet runs cooler with no wearable components. The REDLITHIUM™ 2.0 Compact Battery Pack provides up to 20% more power, 2X more recharges than standard lithium-ion batteries, and best-in-class performance in extreme jobsite conditions. REDLINK PLUS™ intelligence ensures optimized performance and protection from overload, overheating, and over-discharge. The onboard fuel gauge helps you monitor the charge more accurately, so there’s less downtime on the job. The MILWAUKEE® expander is designed for UPONOR® ProPEX® connections to deliver fast potable water installations from expansion to seal.
