The MILWAUKEE® M12 FUEL™ ProPEX® Expander brings a breakthrough in productivity for plumbing installers by delivering the fastest 3/8-in to 1-in expansions. Featuring an auto-rotating head, the Expander provides even expansions for the most consistent installations. In combination with ProPEX® Expander Heads with RAPID SEAL, installers will experience up to 65% faster sealing of connections when temperatures are below freezing, reducing the time spent prior to pressure testing.

An extended dual-actuation trigger and a compact right-angle design allows for easy access in tight locations. All-metal gears and an integrated metal frame deliver maximum jobsite durability. The POWERSTATE Brushless Motor provides the fastest expansions while running cooler and with no wearable components. The REDLITHIUM 2.0 Compact Battery Pack delivers 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 optimal performance and provides overload protection to prevent damage to the tool and battery during heavy applications, while still maintaining compatibility across the entire M12 System. The onboard fuel gauge helps monitor the charge more accurately, reducing downtime on the job site.
