Mueller Streamline COTRED2114112 Copper Reducing Tee

Product Description

The MUELLER STREAMLINE COTRED2114112 is a copper reducing tee designed for plumbing and hydronic piping systems where a branch or run requires a size transition. This fitting connects a 2-inch main run to a 1-1/4-inch outlet and a 1-1/2-inch branch, allowing a single connection point to serve three lines of different diameters. It is fabricated from copper, which provides corrosion resistance and reliable soldered joints in both hot and cold water applications. Licensed plumbers install this type of fitting during new construction, remodel work, and system retrofits where reducing transitions are required within copper distribution lines.

This reducing tee is suited for residential and light commercial plumbing systems that use copper pipe throughout the distribution network. Typical applications include domestic hot and cold water supply lines, radiant heating loops, and mechanical room headers where flow needs to be split and reduced simultaneously. The fitting is appropriate wherever a standard sweat-solder connection is used and a multi-diameter branch point is required.

Key Features

• Copper construction provides natural corrosion resistance for potable water and hydronic systems
• Reducing tee configuration handles three different pipe sizes in a single fitting
• 2-inch main run accommodates higher-flow trunk lines
• 1-1/4-inch and 1-1/2-inch outlets allow stepped-down branch connections without additional reducers
• Sweat-solder ends are compatible with standard copper tubing and common flux-and-solder installation methods

Compatibility

Designed as an OEM-style replacement and new-installation fitting for copper plumbing systems requiring a 2-inch by 1-1/4-inch by 1-1/2-inch reducing tee configuration.

Installation Notes

Installation is performed by a licensed plumber using standard copper sweat-soldering techniques. Shut off the water supply and fully drain the affected lines before cutting or fitting any pipe. Follow local plumbing codes, including applicable IPC requirements, for joint preparation, flux application, and solder type — particularly for potable water systems where lead-free solder is required. Allow joints to cool fully and pressure-test the system before returning it to service.
