Nibco B101050 Cast Copper Tee 1-1/4x1/2x1/2 Cxcxc

Product Description

The NIBCO B101050 is a cast copper reducing tee designed for pressure piping systems in residential and light commercial plumbing and hydronic heating applications. This fitting connects a 1-1/4 inch run with two 1/2 inch branch outlets using a C x C x C (solder cup) end connection on all three ports. Cast copper construction delivers consistent wall thickness and reliable joint integrity under sustained pressure. Licensed plumbers and pipefitters install this fitting where a reduced branch takeoff is needed from a main distribution line. The 0.5 pound weight keeps handling straightforward during rough-in work.

This reducing tee is suited for potable water supply, hydronic radiant or baseboard systems, and general pressure piping where copper soldered joints are specified. The C x C x C configuration accepts standard copper tubing on all ports, making it compatible with conventional sweat-solder installation practice. It is typically found in branch distribution assemblies, manifold rough-ins, and boiler piping layouts where a main line must feed a smaller branch circuit without additional fittings.

Key Features

• Cast copper construction for consistent wall thickness and pressure integrity
• C x C x C solder cup ends on all three ports for standard sweat connections
• Reducing configuration: 1-1/4 inch run x 1/2 inch x 1/2 inch branch outlets
• Pressure fitting rated for use in pressurized plumbing and hydronic systems
• Compact 0.5 pound weight simplifies handling during installation

Compatibility

Designed as an OEM-style pressure fitting replacement for cast copper solder-joint piping systems using standard C x C x C end connections in residential and commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and ASME B16.22 standards for wrought and cast copper fittings. Shut off and depressurize the water supply and drain the line before cutting or soldering. Clean all tube ends and fitting sockets with emery cloth and apply flux prior to soldering; use lead-free solder where required by code for potable water service. Avoid overheating the fitting during the sweat process, as excessive heat can damage flux and compromise joint quality.
