The MILWAUKEE® M18 FUEL™ 2 in ProPEX® Expander w/ ONE-KEY™ is the fastest, lightest, and most compact way to install 2 in ProPEX®. The auto-rotating head mechanism provides uniform expansions for the most consistent installations. The pipe size selector switch optimizes the expansion speed for up to 3X faster connections. The new dedicated 2 in ProPEX® Expander Head's integrated cone design reduces the travel length of the expander's expansion cone, allowing for the most compact 2 in solution. The D-Handle design offers balance and control for one-handed connections. All-metal gears and an integrated metal frame deliver maximum tool durability on the job site. The POWERSTATE™ Brushless Motor allows for the fastest expansions yet runs cooler with no wearable components. The REDLITHIUM™ XC5.0 Extended Capacity Battery provides 20% more power, and 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 Milwaukee M18 FUEL™ 2 in ProPEX® Expander also has ONE-KEY™ to wirelessly connect the tool with a smartphone to track and manage. This ProPEX® expansion tool is designed for UPONOR® ProPEX® connections to deliver fast potable water installations from expansion to seal.
