Mueller Streamline COTRED212212112 Copper Reducing Tee

Product Description

The MUELLER STREAMLINE COTRED212212112 is a copper reducing tee fitting designed for joining and branching copper tubing in plumbing and hydronic systems. The run measures 2.5 inches by 2.5 inches with a reduced branch outlet of 1.5 inches, making it suitable for transitions where a smaller branch line feeds off a larger main. This fitting is installed by licensed plumbers and pipefitters using standard sweat-solder or press-fit methods depending on system requirements. Its all-copper construction resists corrosion and maintains compatibility with potable water and heating system applications.

This reducing tee is used in residential and light commercial plumbing installations where a branch takeoff is needed from a 2.5-inch main line down to a 1.5-inch branch line. Typical applications include domestic hot and cold water distribution, radiant heating supply and return piping, and recirculation loops. The fitting installs in-line wherever a directional branch split and size reduction are required in a single fitting, reducing the need for additional reducers or couplings in the line.

Key Features

• Run size of 2.5 inches by 2.5 inches with a 1.5-inch reduced branch outlet
• All-copper construction for corrosion resistance and long service life
• Combines a tee and reducer function in a single fitting to simplify installation
• Compatible with standard sweat-solder joining methods used in copper piping systems
• Suitable for potable water and hydronic heating applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for copper tubing systems requiring a 2.5-inch by 2.5-inch run with a 1.5-inch branch outlet.

Installation Notes

Installation is typically performed by a licensed plumber. Shut off the water supply and depressurize the line before cutting in the fitting. Clean and flux all joint surfaces before soldering, and follow local plumbing codes such as the IPC for joint preparation and material requirements. Do not apply heat to the fitting while any moisture remains in the line, as this will prevent proper solder flow.
