M12™ LITHIUM-ION ProPEX® Expansion Tool Kit

The Milwaukee M12™ LITHIUM‑ION ProPEX® Expansion Tool Kit is a cordless plumbing installation tool designed to expand ProPEX® PEX‑A tubing quickly and consistently for secure, leak‑free connections. Built on the Milwaukee M12 battery platform, this compact expansion tool features a right‑angle design and auto‑rotating head that make it easy to access and work in tight or confined spaces — common in residential and commercial plumbing applications.

This ProPEX® tool uses a quick cam expansion mechanism that delivers precise, continuous expansion for 3/8″ to 1″ ProPEX® connections, helping installations go faster and more uniformly than manual methods. Its all‑metal gears and integrated metal frame provide rugged jobsite durability, and built‑in LED work lights illuminate dark work areas. An on‑tool fuel gauge shows remaining battery charge so you can manage runtime effectively.
