Milwaukee 3/4" ProPEX Expansion Head M12/M18 49-16-2403
FLAWLESS COLD-EXPANSION PERFORMANCE
For the service plumber, a 3/4" PEX connection isn't just a joint—it's your signature on a job well done. The Milwaukee 49-16-2403 3/4" ProPEX Expansion Head is the industry standard for cold-expansion fittings, specifically optimized for the high-cycle demands of professional service and hydronic repair. Whether you're upgrading a residential boiler or repairing a commercial riser, this head utilizes Milwaukee's auto-rotation technology to provide a perfectly symmetrical expansion, ensuring your Uponor fittings grip the pipe with maximum force every single time, even in the tightest mechanical closets.
- / AUTO-ROTATION OPTIMIZATION: Seamlessly integrates with M12 and M18 ProPEX tools to rotate the head between expansions for a perfectly round bore.
- / CHROME-PLATED STEEL: Industrial-grade construction resists the mineral buildup and oxidation found in harsh, wet water environments.
- / PRECISION MILLED: Specifically designed for Uponor PEX-a tubing to prevent over-stretching and ensure long-term material memory.
- / COLOR-CODED RINGS: High-visibility 3/4" identifier allows for instant tool identification in low-light plumbing vaults or crowded tool bags.
