The ProPEX expander tool from Milwaukee is the only tool currently available for making expander fitting connections. Compatible with Uponor’s PEX-A tubing and ProPEX fittings, the new tool improves upon previous designs. It weighs less and fits into tighter spaces than older models. The tool may be ordered in two different sizes (M12 and M18). The batteries from these tools work with Milwaukee’s wide-range of other M12 and M18 products. Milwaukee packages lithium-ion batteries, a charger, and expander heads with the tool as part of Expansion Tool Kits. Kits also come with grease and a convenient carrying case. For those who already have these accessories, they offer the tool as a stand-alone product.
M12 tools work with heads ranging from 3/8” to 1”. 1/2", 3/4", and 1” heads are included in the M12 kit. The M18 kit includes the larger 1", 1-1/4", and 1-1/2" heads. It can accommodate the smaller M12 heads, but they must be purchased separately.
