Nibco B150550 Cast Copper Drop Tee 3/4 in C X C X F

Product Description

The NIBCO B150550 is a cast copper drop tee designed for pressure piping systems in residential and commercial plumbing applications. The fitting uses a C x C x F end connection configuration, meaning two sweat (solder cup) inlets and one female-threaded outlet, allowing a branch takeoff from a copper run while transitioning to a threaded connection. Cast copper construction meets ASTM B584 and ISO standards, making it appropriate for potable water, hydronic heating, and general pressure piping where code-compliant copper fittings are required. Licensed plumbers and pipefitters are the primary installers.

The B150550 is sized at 3/4 inch and is suited for branch connections in copper distribution lines where a drop outlet to a threaded fitting is needed. Common applications include residential water supply systems, light commercial plumbing, and hydronic heating distribution where a sweat main line must transition to a threaded branch port. The pressure fitting designation confirms it is rated for pressurized service rather than drainage or DWV use.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off and depressurize the water supply and ensure all pipe ends are fully dry before soldering. Clean pipe ends and fitting sockets with emery cloth and apply flux before sweating the C connections; the female-threaded outlet should be wrapped with thread sealant tape or compound before assembling the threaded joint. Do not apply torch heat directly to the threaded portion of the fitting.
