PEX Expanders

0 products

PEX expanders are designed to stretch the ends of cross-linked polyethylene (PEX) Type A tubing along with its expansion ring, facilitating the insertion of cold-expansion fittings. Once expanded, the tubing and ring contract to their original size, creating a secure seal and firmly holding the fitting in place. Cordless PEX expansion tools offer a more consistent and smoother expansion process compared to manual tools, ensuring a tighter and more reliable connection with fittings. Expansion heads are specifically designed to attach to the expander's cone, sliding into tubing of corresponding sizes to prepare it for fitting installation.
