The 20V MAX* 1" PEX Expander, made in the USA with global materials, operates off of the MAX* System, which now totals over 100 products.

The 20V MAX* 1" PEX Expander can expand 3/8 inches to 1 inch PEX-A Tubing. Five interchangeable PEX expander heads in 3/8 inch, ½ inch, 5/8 inch, ¾ inch, and 1 inch are available. The tool rotates each of these heads evenly to ensure consistent expansion around the diameter of the pipe. The PEX Expander features a dual-sided, heavy-duty hang hook and belt hook that can be mounted on either side of the tool. An LED light helps to illuminate the work area. In addition, the long trigger can be actuated at any point, making it easy to use in a variety of orientations between joists or under sinks.
