Midland Industries 77384 Copper Sweat Reducer 6x4 in

Product Description

The MIDLAND INDUSTRIES 77384 is a copper sweat reducer fitting designed to connect two sections of pipe at different diameters. It transitions from a 6-inch fitting connection on one end to a 4-inch fitting connection on the other, making it a practical solution for reducing flow paths in copper piping systems. This type of fitting is joined using a sweat (soldered) connection method, which is standard practice in plumbing and HVAC applications. Licensed plumbers and mechanical contractors typically install this fitting during new construction or retrofit work where pipe size changes are required in a copper distribution system.

This reducer is suited for residential and commercial plumbing systems where copper sweat fittings are specified. It is used in supply lines, drain configurations, and mechanical rooms where a step-down in pipe diameter is needed. The fitting works within standard copper tube size systems and is appropriate for applications that call for a soldered joint rather than a threaded or press-fit connection. Its substantial weight of 5.1 pounds reflects the material content required for a large-diameter copper reducer of this size.

Key Features

• Copper construction for corrosion resistance and long-term durability in wet environments
• Sweat (solder) connection on both ends for a reliable, leak-free joint
• Transitions from 6-inch to 4-inch fitting size in a single piece
• No threads to strip or press tooling required - standard torch and solder installation
• Minimum order quantity of 1, suitable for single-unit service calls or larger projects

Compatibility

Designed as an OEM-style copper sweat reducer for use in standard copper tube plumbing and mechanical piping systems requiring a 6-inch to 4-inch diameter reduction.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical contractor in accordance with the International Plumbing Code (IPC) and applicable local codes. Before soldering, shut off and depressurize the water or fluid supply and ensure the pipe interior is dry, as moisture will prevent a sound solder joint. Clean both the pipe ends and the fitting socket with emery cloth and apply flux before heating. Avoid overheating the fitting, which can damage the copper or burn off the flux before solder flows properly.
