Product Description
Milwaukee 1/2 in. ProPEX Expansion Head for M12 Expansion Tool
Model Number: 49-16-2404
The Milwaukee 49-16-2404 is a 1/2 in. ProPEX Expansion Head for the Milwaukee M12 ProPEX Expansion Tool — the interchangeable expansion head that expands PEX-A tubing at the 1/2 in. diameter for ProPEX fitting connections in residential and light commercial plumbing, radiant floor heating, and hydronic systems. ProPEX connections use the PEX-A tubing's thermal memory property — the expansion head stretches the tubing end and its ProPEX ring over the larger fitting body, and as the expanded tubing cools, it contracts back toward its original diameter to create a watertight, mechanically secure connection around the fitting without the solvent welding, soldering, or crimping required by other connection methods. The Milwaukee M12 expansion tool's cordless platform performs the expansion cycle with battery-powered motor force, replacing the manual effort of hand expansion tools with consistent, controlled expansion for faster installation pace and reduced hand fatigue over a full day of ProPEX connection work.
The 1/2 in. expansion head is the smallest standard ProPEX connection size, covering the residential supply line sizes used for fixture connections, branch lines from manifolds, and the distribution tubing runs in residential plumbing systems where 1/2 in. PEX-A is the standard size. Expansion heads are interchangeable on the M12 ProPEX Expansion Tool, allowing the same tool to serve all standard PEX-A connection sizes by swapping the head without tools between 1/2 in., 3/4 in., and 1 in. operations within the same installation. Milwaukee manufactures the expansion head to the ProPEX system's dimensional requirements for the correct expansion diameter and depth that creates the secure, leak-free connections that plumbing code compliance requires.
