Midland Industries 77200 Copper Sweat Reducing Coupling

Product Description

The MIDLAND INDUSTRIES 77200 is a copper sweat reducing coupling designed to connect pipe runs of two different diameters in a single fitting. With a 6-inch connection on one end and a 3-inch connection on the other, this fitting handles significant step-downs in copper piping systems. It is used in plumbing, mechanical, and HVAC hydronic applications where flow must transition between larger and smaller copper lines. At 6.43 pounds, this is a substantial fitting suited for commercial or heavy residential installations. Licensed plumbers and pipefitters are the primary installers of this type of coupling.

This reducing coupling fits into copper sweat piping systems where a direct 6-inch to 3-inch diameter reduction is required. It is appropriate for use in water supply, hydronic heating, chilled water distribution, and similar wet piping systems that use copper sweat connections. The fitting is joined using standard soldering or brazing techniques common to copper sweat work.

Key Features

• 6-inch to 3-inch step-down configuration handles significant diameter reductions in a single fitting
• Copper construction provides corrosion resistance and long service life in wet piping systems
• Sweat-connect ends are compatible with standard copper tube and soldering methods
• Weighs 6.43 pounds, indicating heavy-wall or large-diameter copper construction suitable for commercial applications

Compatibility

Designed as an OEM-style copper sweat reducing coupling for use with standard 6-inch and 3-inch copper pipe in plumbing and mechanical piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC and local plumbing code requirements. Shut off and drain the water supply completely before cutting into an existing line and fitting this coupling. Clean and flux all mating surfaces thoroughly before soldering or brazing to ensure a leak-free joint. Allow the fitting to cool completely before restoring flow and pressure-testing the connection.
