Nibco B154400 Cast Copper Tee 1/2 in C X C X M

Product Description

The NIBCO B154400 is a cast copper pressure tee fitting designed for soldered copper piping systems. It features a C x C x M end connection configuration, meaning two sweat-socket (cup) inlets and one male-end outlet, making it suitable for branch take-offs where a male-threaded or male-sweat transition is required. The fitting is manufactured from cast copper conforming to ASTM B584, ensuring material consistency and pressure integrity. Weighing 0.14 pounds, it is a compact, durable fitting intended for installation by licensed plumbers and pipefitters working on residential or light commercial water distribution systems.

The B154400 is sized at 1/2 inch and is used in pressure piping applications where a tee branch connection is needed in copper tubing runs. Typical install scenarios include domestic hot and cold water supply lines, hydronic heating branch connections, and similar pressure piping systems. Its C x C x M configuration is well suited for transitions at valves, service connections, or equipment stubs within a copper distribution system.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off and drain the water supply before cutting into any existing piping. Clean and flux all cup ends thoroughly before soldering to ensure a leak-free joint. Do not apply torch heat directly to the fitting body longer than necessary to achieve proper solder flow.
