Midland Industries 77355 Copper Reducer Coupling 1-1/4 X 3/4 in

Product Description

The MIDLAND INDUSTRIES 77355 is a copper reducer coupling designed to connect two different pipe sizes in a sweat-soldered plumbing system. It transitions from a 1-1/4 inch fitting end to a 3/4 inch sweat end, allowing a plumber to step down pipe diameter without additional adapters. Rated to 400 psi and suitable for operating temperatures from 32 degrees F to 200 degrees F, this fitting handles both domestic water and general plumbing applications where a size reduction is needed in a copper line.

This reducer coupling is used in residential and light commercial plumbing systems where copper sweat connections are standard. Typical install scenarios include water supply line reductions at branch points, fixture supply drops, and equipment connections where a main line steps down to a smaller service line. It is installed by licensed plumbers or experienced pipefitters working with copper sweat systems.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off the water supply and fully drain the line before soldering to ensure a clean, dry joint. Use appropriate flux, lead-free solder, and a properly sized torch for copper sweat connections. Allow the fitting to cool completely before restoring water pressure and inspecting for leaks.
