Midland Industries 77277 Reducer Coupling 2 in X 1 in Copper

Product Description

The MIDLAND INDUSTRIES 77277 is a copper reducer coupling with stop designed to connect two sections of copper tubing of different diameters in a sweat (soldered) joint system. It steps down from a 2-inch connection on one end to a 1-inch connection on the other, with an internal stop that ensures consistent insertion depth for a reliable, leak-free joint. Rated to 400 psi and suitable for service between 32 and 200 degrees F, this fitting is built for use in residential and light commercial plumbing and hydronic systems. Plumbers and pipefitters install this fitting as part of copper sweat assemblies wherever a pipe size reduction is required.

This reducer coupling with stop is used in potable water supply, hydronic heating, and general plumbing distribution systems where a transition from 2-inch copper to 1-inch copper is needed. The sweat-connect ends are compatible with standard Type K, L, and M copper tubing. It is appropriate for both new construction and retrofit or repair applications. Its compact profile allows installation in tight spaces within wall cavities, mechanical rooms, and utility chases.

Key Features

• Reduces from 2-inch to 1-inch copper sweat (C x C) connections
• Internal stop ensures correct seating depth for consistent solder joints
• Rated to 400 psi working pressure
• Temperature range: 32 to 200 degrees F
• Copper construction for corrosion resistance in water service applications

Compatibility

Designed as an OEM-style replacement and standard-use fitting for copper sweat piping systems using 2-inch and 1-inch nominal copper tubing conforming to standard dimensional tolerances.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the water supply and drain the affected line before cutting or disassembling any piping. Clean and flux both the tube ends and the fitting sockets thoroughly before soldering to ensure a sound joint. Avoid overheating the fitting during the soldering process, as excessive heat can damage the fitting or surrounding materials.
