Question 1

What size PEX does the Milwaukee 49-16-2415 ProPEX Expander Head fit?

Accepted Answer

The Milwaukee 49-16-2415 is a 5/8 in ProPEX Expander Head designed specifically for PEX expansion applications. Its size marking identifies the head for 5/8 in ProPEX work. Users should select the expander head size that corresponds to the PEX connection being installed rather than assuming that different ProPEX head sizes are interchangeable.

Question 2

Which Milwaukee expansion tools are compatible with the 49-16-2415 expander head?

Accepted Answer

The 49-16-2415 is compatible with Milwaukee M12 and M18 Expanders except the M18 FORCE LOGIC ProPEX Expansion Tool, identified in the specifications as model 2633. It is also optimized for use with the M12 FUEL ProPEX Expander. Verify the exact tool model before installation to ensure the expander head is supported.

Question 3

How does RAPID SEAL work on the Milwaukee ProPEX expander head?

Accepted Answer

RAPID SEAL is designed to provide consistently fast sealing as temperatures decrease. Milwaukee states that the expansion head segments can deliver up to 65% faster sealing of connections as temperatures decrease. This feature is intended to reduce the time before a pressure test can begin during compatible ProPEX installation work.

Question 4

What materials are used in the Milwaukee 49-16-2415 expander head?

Accepted Answer

The Milwaukee 49-16-2415 uses chrome-plated segments and a black oxide collar. The chrome plating is specified for weather and corrosion resistance, while the high-strength steel construction supports the expander head's durability. These material features are combined with precision-engineered components for accurate PEX expansions in compatible installation applications.

Question 5

How can I identify the correct Milwaukee ProPEX expander head size?

Accepted Answer

The 49-16-2415 has size markings on the ring and collar surfaces to make identification easier from different orientations. This model is specifically marked for 5/8 in ProPEX applications. Checking the visible size marking before installation can help users select the appropriate expansion head when working with multiple Milwaukee ProPEX head sizes.
