Midland Industries 77373 Copper Reducer 3 X 1-1/4 Inch

Product Description

The MIDLAND INDUSTRIES 77373 is a copper sweat reducing coupling designed to connect pipe runs of two different diameters in a single inline fitting. It transitions from a 3-inch fitting end to a 1-1/4-inch fitting end using standard sweat (solder) connections on both sides. This type of fitting is a routine component in residential and commercial plumbing and hydronic systems wherever a pipe size change is required along a run. Licensed plumbers and pipefitters install this fitting as part of new construction, retrofit, or repair work. The fitting weighs 1.07 pounds and is fabricated from copper, making it compatible with standard copper tube and sweat-joint assembly practices.

This reducing coupling is suited for plumbing supply lines, hydronic heating distribution piping, and other copper sweat systems that require an inline reduction from 3-inch pipe to 1-1/4-inch pipe. It is appropriate for both residential and light commercial installations where a direct, soldered reduction is preferred over a threaded or push-fit alternative. The straight inline design keeps the transition compact and minimizes flow restriction through the size change.

Key Features

• 3-inch sweat fitting on one end, 1-1/4-inch sweat fitting on the other end for a direct inline pipe reduction
• Copper construction supports soldered sweat-joint assembly per standard trade practice
• Inline reducing coupling design keeps the transition tight and flow-efficient
• Single-piece fitting eliminates the need for a coupling plus a separate reducer in the run
• Minimum order quantity of 1 unit

Compatibility

Designed as an OEM-style replacement or new-installation fitting for copper sweat piping systems requiring an inline reduction from 3-inch to 1-1/4-inch pipe diameter.

Installation Notes

Installation should be performed by a licensed plumber following applicable local plumbing codes and IPC guidelines. Shut off water supply and depressurize the line before cutting into any existing piping. Pipe ends must be cut square, deburred, and cleaned before applying flux and solder. Do not use open flame near combustible materials, and ensure adequate ventilation when soldering.
