Midland Industries 77352 Copper Reducer Coupling 1x1/2 in

Product Description

The MIDLAND INDUSTRIES 77352 is a copper reducer coupling designed to connect two sections of tubing at different diameters within a plumbing or hydronic system. It transitions from a 1-inch fitting end to a 1/2-inch sweat (C) end, allowing a licensed plumber or pipefitter to reduce line size without additional adapters. Rated to 500 psi and suitable for operating temperatures from 32 to 200 degrees F, this fitting is built for reliable performance in residential and light commercial water supply and distribution applications. The copper construction ensures compatibility with standard sweat-soldering installation methods.

This reducer coupling is used in water supply lines, hydronic heating distribution systems, and plumbing rough-in work where a step-down in pipe diameter is required. It is commonly installed during new construction, remodel work, or service calls where line sizing changes at branch points, fixture connections, or equipment inlets. The sweat connection on the smaller end joins directly to 1/2-inch copper tubing using standard solder and flux.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off and depressurize the water supply and allow all pipe sections to cool completely before soldering. Clean and flux both the tubing and fitting socket surfaces before applying heat; overheating can damage the fitting or cause incomplete solder joints. Inspect the joint for full solder penetration after installation before returning the system to service.
