1 in. PEX-A x 1 in. NPT Female Adapter (NSF Lead Free Brass F1960 PEX Cold Expansion Fitting)

The 247Garden 1 in. PEX-A Expansion x Female HEX Adapter is a premium plumbing fitting engineered for high-performance potable water and hydronic heating systems. Designed for 1 inch PEX-A tubing, this adapter delivers superior durability, corrosion resistance, and long-term reliability through its lead-free, dezincification-resistant (DZR) brass construction, making it ideal for residential, commercial, and industrial plumbing applications.

Featuring a cold-expansion design, this adapter creates secure, leak-free connections when used with 1-inch Expansion PEX rings (sold separately). Its female HEX end easily mates with standard 1-inch threaded outlets, enabling seamless integration into manifold systems, hydronic loops, and complex water delivery layouts. The larger internal diameter provides up to 25% greater flow than standard PEX fittings, ensuring efficient water distribution throughout your plumbing system.

Installation and Performance:

This adapter is designed for use with 247Garden Expansion PEX rings or compatible expansion-type rings (sold separately). Installation requires a cold-expansion tool (sold separately), which expands the PEX tubing over the barbed end of the adapter. As the tubing contracts, a secure, permanent seal forms without the need for go/no-go gauges. Cold-expansion fittings ensure reliable connections, reduce installation errors, and maintain system integrity under high pressure and temperature conditions.
