Choose the Correct Fit
Match 1/2 in tubing, ring and ProPEX fitting requirements. A matching nominal size does not make other tubing systems equivalent.
Milwaukee lists compatibility with its M12 and M18 ProPEX expanders. Confirm your exact model and head capacity before fitting.
Installation & Care
Remove the battery and clear dirt from the head. Apply a thin layer of specified expander-cone grease to the cone, then hand-tighten the head securely.
Follow the tubing and fitting maker’s expansion procedure. Keep the segments clean and avoid excess grease.

Important Product Questions
Is this for any type of PEX tubing?
It is specified for Uponor PEX-a tubing and ProPEX fittings. Check the approved tubing and fitting system rather than relying on the PEX name alone.
Will it fit an Uponor manual tool?
Milwaukee says these heads fit most Uponor tools, which is not a universal model-by-model guarantee. Verify your exact tool before ordering.
How should the head be lubricated?
Use the specified expander-cone grease sparingly on a clean cone. The Milwaukee service instructions call for a thin coat and warn against over-lubrication.
