A manual PEX-A expansion tool kit designed to expand PEX-A tubing so fittings can be inserted using the cold-expansion method (ASTM F1960). The kit typically includes a hand expansion tool and interchangeable heads (1/2 in., 3/4 in., and 1 in.), making it suitable for a range of plumbing sizes.

This type of tool is used in potable water and hydronic systems, where the pipe expands and then contracts tightly around the fitting to create a secure, leak-resistant connection.

• Includes expansion heads (1/2 in., 3/4 in., 1 in.)
• Designed for PEX-A cold expansion systems (ASTM F1960)
