Expansion Tools for PEX and Plumbing Tube Systems

Expansion tools are essential for installing PEX and other expandable tubing systems that rely on cold expansion connections. By uniformly expanding the pipe and fitting, these tools create tight, long-lasting joints once the material contracts around the connection. Choose from manual, battery-powered and electric expansion tools sized for common tubing diameters used in potable water, radiant heating and plumbing distribution.

Our selection includes interchangeable expansion heads, cone assemblies and accessories that match leading PEX system specifications. Use expansion tools alongside compatible pipe fittings and manifolds to complete full home-run or trunk-and-branch layouts. Many kits ship in protective cases for easy transport to and from the jobsite.

For best results, pair your expansion tools with quality PEX tubing and follow manufacturer guidelines for expansion cycles, ambient temperature and tool maintenance. Whether you are building new systems or adding zones to existing installations, the right expansion equipment helps ensure consistent, leak-resistant connections.
