Midland Industries 77195 Copper Sweat Reducing Coupling

Product Description

The MIDLAND INDUSTRIES 77195 is a copper sweat reducing coupling used to transition between two different pipe diameters in a copper piping system. It connects a 4-inch pipe on one end to a 3-inch pipe on the other, making it a standard component for reducing flow path diameter in residential and commercial plumbing installations. The fitting is manufactured from copper and is designed for sweat (solder) connection on both ends. Plumbers and pipefitters install this coupling during new construction, renovation, and repair work wherever a pipe diameter change is required in a copper system.

This reducing coupling is suited for potable water supply lines, hydronic heating distribution piping, and general copper plumbing systems. It is appropriate for both residential and light commercial applications. The sweat connection method makes it compatible with standard copper tube sizes and installation practices common across the plumbing trade. It is typically installed in accessible locations such as mechanical rooms, utility spaces, and above-ceiling runs where diameter transitions are needed.

Key Features

• Reduces from 4 inches to 3 inches in a single fitting
• Copper construction for corrosion resistance and long service life
• Sweat (solder) connection on both ends for a leak-tight joint
• Weighs 2.26 pounds - suitable for supported piping runs
• Minimum order quantity of 1 unit

Compatibility

Designed as an OEM-style replacement and standard-use fitting for copper sweat piping systems requiring a 4-inch to 3-inch diameter reduction.

Installation Notes

This fitting is installed by licensed plumbers following local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the system before cutting into existing pipe. Clean and flux all mating surfaces before applying solder, and ensure full joint penetration per standard sweat soldering practice. Allow the joint to cool fully before restoring system pressure.
