Midland Industries 77502 Copper Reducing Tee 1x1/2x3/4 in

Product Description

The MIDLAND INDUSTRIES 77502 is a copper reducing tee designed for sweat (solder) connections in plumbing and HVAC hydronic systems. It joins three lines of different diameters in a single fitting, with a 1-inch run inlet, a 3/4-inch run outlet, and a 1/2-inch branch outlet, all using standard copper sweat connections. Rated to 500 psi and suitable for service temperatures from 32 degrees F to 200 degrees F, this fitting handles both domestic water supply and light commercial hydronic applications. At 0.34 pounds, it is a compact, full-copper fitting intended for installation by licensed plumbers and HVAC technicians.

This reducing tee is used wherever a copper sweat distribution system requires a size transition at a branch point. Typical applications include residential and light commercial water supply lines, radiant heating distribution manifolds, and HVAC hydronic piping. The three-port reducing configuration eliminates the need for additional bushings or adapters when routing flow to a smaller branch line off a larger main, keeping the installation clean and minimizing potential leak points.

Key Features

• Three-port reducing design: 1 inch C x 1/2 inch C x 3/4 inch C sweat connections
• 500 psi pressure rating for demanding water supply and hydronic service
• Temperature range of 32 degrees F to 200 degrees F covers typical plumbing and low-temperature hydronic use
• Full copper construction for corrosion resistance and long service life
• Eliminates additional reducing bushings at branch transitions

Compatibility

Designed as an OEM-style sweat fitting compatible with standard copper tubing systems using Type K, L, or M copper tube at the specified port sizes.

Installation Notes

Installation should be performed by a licensed plumber in accordance with IPC and local plumbing codes. Shut off and drain the water supply completely before cutting into existing lines. All mating tube ends must be cut square, deburred, cleaned with emery cloth, and fluxed before soldering to achieve a leak-free joint. Do not apply heat to a fitting that still contains water, as steam pressure can cause joint failure.
