Product Description
Milwaukee 2-1/2 in. ProPEX Expansion Head
Model Number: 49-16-2616
The Milwaukee 49-16-2616 is a 2-1/2 in. ProPEX Expansion Head for use with Milwaukee M18 ProPEX Expansion Tools — a precision-machined expansion head attachment that performs PEX-A tubing expansion operations at the 2-1/2 in. pipe size for plumbing and radiant heating system installations. The ProPEX expansion method stretches the end of PEX-A tubing along with a ProPEX expansion ring over a fitting body, and as the expanded tubing and ring recover toward their original diameter, they form a compression grip connection of exceptional strength and leak resistance. Milwaukee's 2-1/2 in. ProPEX Expansion Head is precision-engineered for accurate, consistent expansion geometry at this pipe size on every cycle — ensuring that the tubing and ring expand to the correct diameter for proper fitting engagement regardless of operator variation across hundreds of connections per day on large commercial plumbing projects.
The 2-1/2 in. pipe size serves large-diameter commercial plumbing distribution mains, hydronic heating system main loops, and large commercial plumbing applications where the flow capacity and pressure ratings of 2-1/2 in. PEX-A tubing meet the system design requirements. The expansion head attaches to Milwaukee's ProPEX Expansion Tool body using the standard head interface that allows a single expansion tool motor to be used across multiple pipe sizes simply by swapping heads — a significant equipment cost efficiency for plumbing contractors who work across multiple pipe size ranges on the same projects. Milwaukee's ProPEX heads are available from 1/2 in. through 3 in. for complete PEX-A installation coverage across all residential and commercial plumbing pipe sizes. Always verify that expansion rings, tubing, and fittings are all specified for the same nominal pipe size before making connections.
Note: ProPEX connections require PEX-A tubing — not compatible with PEX-B or PEX-C tubing types which cannot be expanded with this method.
