The MILWAUKEE® 2” ProPEX® Expander Head for M18 FUEL™ 2” ProPEX® Expander is precision engineered for accurate expansions and auto-rotating compatibility. The integrated cone design of the 2” head reduces the travel length of the expander’s expansion cone, allowing for the most compact expansion cycle. Made from high-strength steel, the chrome-plated segments, and black oxide ring combine durability and weather resistance. Size markings on ring and collar surfaces provide easy recognition at any orientation. This head is designed exclusively for the M18 FUEL™ 2” ProPEX® Expander Tool. For best performance, use 150g ProPEX® Expander Grease and 2” Head Applicator (49-08-2403) to grease the integrated cone and collar of the ProPEX® expansion head.
