Midland Industries 77512 Copper Sweat Reducing Tee

Product Description

The MIDLAND INDUSTRIES 77512 is a reducing copper sweat tee designed for joining three copper lines at a single point with three different diameters. Port one accepts 1-1/4 inch copper tubing, port two accepts 1 inch copper tubing, and port three accepts 3/4 inch copper tubing, all using solder-joint (sweat) connections. This fitting is used by licensed plumbers and HVAC technicians in water distribution, hydronic heating, and refrigeration piping systems where branch lines change in diameter. At 0.43 pounds, it is a compact, lightweight component suited for both new construction and retrofit work.

This tee fits into residential and light commercial plumbing and mechanical systems wherever a run of copper pipe must branch off at a reduced size. Common applications include domestic hot and cold water supply lines, hydronic radiant heating loops, and chilled water systems. The solder-joint connection type requires standard copper sweat assembly practices and is compatible with Type L and Type K copper tubing of the corresponding sizes.

Key Features

• Three-port reducing configuration: 1-1/4 inches x 1 inch x 3/4 inch
• All-copper construction for corrosion resistance and long service life in wet systems
• Sweat (solder-joint) connections on all three ports for secure, leak-free joints
• Lightweight at 0.43 pounds, minimizing load on pipe hangers and supports
• Minimum order quantity of one unit, suitable for single-fitting replacement jobs

Compatibility

Designed as an OEM-style copper sweat reducing tee for use with Type K and Type L copper tubing in plumbing and hydronic mechanical piping systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical contractor in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and fully drain the affected lines before cutting into the pipe. Clean all mating surfaces with emery cloth and apply flux before soldering to ensure a sound, leak-free joint. Avoid overheating the fitting during soldering, as excessive heat can damage the copper and compromise joint integrity.
