Midland Industries 77257 Copper Sweat Reducing Coupling

Product Description

The MIDLAND INDUSTRIES 77257 is a copper sweat reducing coupling used to connect two pipe segments of different sizes in a plumbing or refrigeration system. It transitions from a 1/2-inch connection on one end to a 1/8-inch connection on the other, allowing a technician to reduce line size without additional adapters. The fitting is manufactured from copper and is designed for sweat (solder) installation. Plumbers and HVAC technicians install this type of fitting during new construction, retrofit work, or repair on copper piping systems where a direct size reduction is needed.

This reducing coupling is suited for residential and light commercial plumbing and HVAC applications where copper sweat fittings are specified. It fits into standard copper piping runs that require a step-down from 1/2-inch to 1/8-inch pipe. The compact size and low weight make it a practical component to carry as a service stock item on service calls or planned installations.

Key Features

• Reduces from 1/2-inch to 1/8-inch connection in a single fitting
• Copper construction for durability and solder compatibility
• Sweat-connection design suits standard soldering installation practices
• Lightweight at 0.03 pounds for easy handling and stocking
• Minimum order quantity of 1 unit

Compatibility

Designed as an OEM-style replacement or new-installation reducing coupling for copper sweat piping systems requiring a 1/2-inch to 1/8-inch size transition.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local codes and IPC guidelines. Shut off and depressurize the water or refrigerant line before cutting into the system. Clean and flux both pipe ends before soldering to ensure a leak-free joint. Avoid overheating the fitting during soldering, as excessive heat can compromise the integrity of the copper.
