Midland Industries 77531 Copper Sweat Reducing Tee

Product Description

The MIDLAND INDUSTRIES 77531 is a reducing copper sweat tee designed for use in plumbing and mechanical piping systems. It features three solder-cup (C) connections: 1-1/2 inches on the run ends and a 1-inch reducing branch in the center. This configuration allows a main line to continue at full size while directing flow to a smaller branch line. The fitting is constructed from copper, making it well suited for potable water, hydronic heating, and general plumbing distribution applications. Licensed plumbers and pipefitters install this type of fitting as part of copper sweat assemblies throughout residential and light commercial construction.

This reducing tee is appropriate for residential and light commercial plumbing systems where a 1-1/2-inch copper main line requires a 1-inch branch takeoff. Typical applications include domestic hot and cold water distribution, hydronic heating loops, and similar closed-loop or supply piping configurations. The sweat-connect design integrates cleanly into standard Type K, L, or M copper tube assemblies where soldered joints are specified or required by local code.

Key Features

• Reducing tee configuration: 1-1/2 inches x 1 inch x 1-1/2 inches for branch reduction without additional fittings
• All three ends use solder-cup (C) connections for reliable sweat-soldered joints
• Copper construction provides corrosion resistance and long service life in water systems
• Compact, lightweight design at 0.87 pounds for easy handling and installation
• Compatible with standard copper tube and solder-joint fittings per common plumbing codes

Compatibility

Designed as an OEM-style replacement and new-installation copper sweat reducing tee for use with standard 1-1/2-inch and 1-inch copper tube in residential and light commercial plumbing systems.

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 system and allow all pipes to cool completely before cutting or fitting. Clean and flux all mating surfaces thoroughly before soldering, and use lead-free solder where required by code for potable water applications. Avoid overheating the fitting during the sweat process, as excessive heat can compromise the joint integrity.
