PEX-A Expansion Tool Kit, Three Heads

Cold water lines run through crawl spaces and joist bays where bulky gear will not fit. We built this manual expander from aluminum alloy and chrome-plated steel to open type-A tubing for expansion fittings without needing a power outlet. It handles the three common line sizes on residential supply runs.

What this one is built to do

Type-A expansion only

This tool opens type-A tubing so it can slip over standard expansion fittings and shrink back down around the barb. It will not work on type-B lines, which require crimp rings.

Three steel heads

Thread one of the three expansion heads onto the drive cone to match the tubing size in your hand. The plated spring steel segments spread evenly as you squeeze the long handles.

Cutter in the box

A clean square cut is where every good joint starts. We pack a handheld tube cutter right in the case so you do not have to hunt through your bucket for one.

Carrying case and lube

The hard case holds the expander body, the cutter, the heads, and a tube of lubricant. A dab of grease on the drive cone keeps the segments sliding smooth through repeated pulls.
