Watts Brass Tubular 3510-1008 Quick Connect Adapter

Product Description

The WATTS BRASS TUBULAR 3510-1008 is a quick connect straight adapter designed to transition from 1/2-inch Copper Tube Size (CTS) to 1/2-inch Female Pipe Thread (FPT). Rated to hold up to 250 PSI, it provides a fast, tool-free connection for PEX, copper, and CPVC tubing. The single-piece design eliminates loose components that can be misplaced during installation. To connect, simply cut the pipe squarely and push the tubing into the fitting end until it seats at the stop. To disconnect, pull back on the release ring. Licensed plumbers and pipe fitters install this type of adapter in both new construction and repair applications.

This adapter is suited for residential and light commercial plumbing projects where a reliable, tool-free transition fitting is needed. It is approved for behind-wall installations without access panels and for direct in-ground burial, making it suitable for a wide range of rough-in and service scenarios. It performs well as a replacement for Qest and Flare-It type fittings in existing systems running PEX, copper, or CPVC pipe. Each package contains 5 pieces.
