Constructed from solid brass, this fitting provides a reliable three-way connection point in supply lines where a branch takeoff is required. The lead-free construction meets current safe drinking water standards, making it appropriate for installations in residential and light commercial water supply applications. Licensed plumbers and pipefitters select this fitting where a threaded tee connection is needed in 3/8-inch line runs.
This fitting is suited for residential and light commercial plumbing systems where a 3/8-inch threaded branch connection is required. Typical installations include domestic water supply branch lines, fixture supply connections, and similar low-pressure distribution piping. The threaded ends allow straightforward connection using standard pipe thread fittings without specialized tooling.
Designed as an OEM-style replacement or new-installation fitting for standard 3/8-inch threaded plumbing systems in residential and light commercial applications.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve line pressure before removing any existing fittings or making new connections. Apply appropriate thread sealant or PTFE tape to all male threads before assembly to ensure a leak-free joint. Do not overtighten threaded connections, as brass fittings can be damaged by excessive torque.
