Mueller Streamline COTRED211434 Copper Reducing Tee

Product Description

The MUELLER STREAMLINE COTRED211434 is a copper reducing tee designed to join three sections of copper pipe at different diameters within a single fitting. It connects a 2-inch run on the main line, reduces to a 1-1/4-inch outlet on the branch, and steps down further to a 3/4-inch outlet, allowing flow to be split and redirected across multiple line sizes in one assembly. This fitting is a standard soldered connection component used in residential and light commercial plumbing systems. Licensed plumbers install it during new construction rough-in work and during retrofit or repair jobs where existing lines branch off at reduced diameters.

This reducing tee is suited for potable water supply lines, hydronic heating distribution piping, and general-purpose copper plumbing systems where three different pipe sizes must meet at a single junction. Its reducing configuration eliminates the need for additional bushings or adapters at the branch connection, making it a practical choice wherever a 2-inch main must tee off to smaller downstream lines.

Key Features

• Three-port reducing configuration: 2 inches x 1-1/4 inches x 3/4 inches
• Copper construction for corrosion resistance and long service life in water systems
• Solder-joint (sweat) ends compatible with standard copper pipe and fittings
• Reduces the need for additional adapter fittings at the branch connection
• Suitable for potable water and hydronic piping applications

Compatibility

Designed as an OEM-style replacement and new-installation fitting for standard copper plumbing systems using 2-inch, 1-1/4-inch, and 3/4-inch copper pipe.

Installation Notes

Installation requires a licensed plumber and must comply with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and fully drain the affected lines before cutting or soldering. Clean all pipe ends and fitting sockets with emery cloth and apply flux before soldering to ensure a leak-free joint. Allow the fitting to cool completely before restoring water pressure and inspecting all joints for leaks.
