Our M18 FUEL™ ProPEX™ 2" Expander with ONE-KEY™ is the fastest, lightest, and most compact way to install 2" ProPEX™. The auto-rotating head mechanism provides even expansions for the most uniform installations. You can make connections up to 3X faster by using the pipe size selector to optimize expansion speed. The integrated cone design of the new exclusive 2" ProPEX™ expansion head reduces the expansion cone stroke length, creating the most compact 2" solution. The D-handle design offers superior balance and control for one-handed connections. All-metal gears and an integrated metal frame ensure maximum tool durability on the job site. The POWERSTATE™ brushless motor produces the fastest expansions, but runs cooler with no wearing components. The REDLITHIUM™ XC5.0 extended capacity battery provides up to 20% more power, 2X more recharges than ordinary lithium-ion batteries, and best-in-class performance in the most demanding conditions. REDLINK PLUS™ Intelligence circuitry ensures optimal performance while protecting against overload, overheating, and over-discharge. The MILWAUKEE™ M18 FUEL™ 2" ProPEX™ Expander also features ONE-KEY™, allowing you to wirelessly connect the tool to your smartphone to track and manage the tool. This ProPEX™ expander is designed for UPONOR™ ProPEX™ connections to achieve fast potable water installations from expansion to sealing.
