Copper to PEX Adapters

68 products

Showing 1 - 68 of 68 products

A copper to PEX adapter joins PEX tubing to existing copper pipe. One end connects to the PEX, and the other end is soldered (sweated) to the copper. These fittings are the standard way to repipe in PEX, extend an older copper system, or tie in a new fixture.

This collection includes PEX sweat adapters for each major PEX connection method. Crimp (F1807) adapters from Sioux Chief, HeatLink, Legend Valve and Viega PureFlow work with copper crimp rings. Expansion (F1960) adapters from MrPEX, HeatLink and Sioux Chief work with expansion rings. Viega PureFlow press adapters are made with a press tool. You will find male and female sweat ends, FTG (fitting) ends that slip inside another fitting, sweat adapter elbows, and reducing sizes from 3/8" up to 2".

Match the PEX end to the tubing and tools you use, and match the sweat end to the copper size. Solder the copper side before you connect the PEX, so the heat does not damage the tubing.

Shop more PEX crimp fittings, F1960 expansion fittings, Viega PureFlow press fittings and PEX tubing.
