The WATTS BRASS TUBULAR 3517-08 is a 3/8-inch Copper Tube Size (CTS) quick connect elbow fitting designed for fast, tool-free connections in residential and light commercial plumbing systems. Rated to hold up to 250 PSI, this single-piece fitting requires no additional parts to assemble or keep track of during installation. The push-to-connect design accepts PEX, copper, and CPVC tubing — simply cut the pipe cleanly, push it into the fitting end until it seats at the stop, and the connection is complete. Licensed plumbers and experienced pipe fitters install this type of fitting for new construction and repair work alike. Each package contains 5 fittings.
This elbow fitting is suited for residential and commercial plumbing repair and new installation projects involving PEX, copper, or CPVC pipe in 3/8-inch CTS. It is code approved for behind-wall installations without access panels and for direct in-ground burial, expanding its usefulness across a wide range of rough-in and retrofit scenarios. The fitting can also be disconnected by pulling back on the release ring, making it a practical choice in situations where future serviceability matters. It serves as a direct replacement for Qest and Flare It type fittings in compatible applications.
Compatible with 3/8-inch CTS PEX, copper, and CPVC pipe and tubing. Approved as a replacement for Qest and Flare It type fittings in compatible plumbing systems.
Installation is performed by a licensed plumber or qualified pipe fitter. Shut off the water supply and relieve system pressure before cutting into any existing line. Cut pipe ends cleanly and squarely — a deburred, clean cut ensures a proper seat inside the fitting. No pipe dope, sealant tape, or compression tools are required for this push-to-connect design; follow all applicable IPC and local plumbing code requirements for the installation environment.
