Midland Industries 77224 Solder Joint Coupling 1 in Copper

Product Description

The MIDLAND INDUSTRIES 77224 is a wrot copper solder joint coupling without a tube stop, designed for 1-inch C x 1-inch C sweat connections in copper piping systems. The absence of a tube stop allows a tube to pass through completely, making it useful for repair and splice applications where a standard stop-style coupling cannot be used. Rated to 500 psi and suitable for service temperatures from 32 degrees F to 200 degrees F, this fitting is built for reliable performance in residential and light commercial plumbing and hydronic systems. It is installed by licensed plumbers and experienced pipefitters using standard soldering techniques.

This coupling is used in copper sweat piping systems where a full-bore, no-stop fitting is required. Typical applications include repair work on existing copper lines, in-line splices on potable water distribution systems, and hydronic heating piping. The 1-inch diameter suits common branch and main line sizes found throughout residential and light commercial construction. The wrot copper construction meets the demands of both pressure and temperature cycles typical in these environments.

Key Features

• No tube stop design allows tubing to pass fully through for repair and splice work
• Wrot copper construction for strength and corrosion resistance in water service
• Rated to 500 psi working pressure
• Temperature range of 32 degrees F to 200 degrees F
• 1-inch C x 1-inch C sweat connection on both ends
• Lightweight at approximately 0.1 pounds

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 1-inch copper tubing sweat systems in residential and light commercial plumbing and hydronic piping applications.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter following local plumbing codes and IPC guidelines. Shut off and drain the water supply before cutting into any existing line. Clean and flux all mating surfaces thoroughly before applying heat, and allow the joint to cool completely before restoring pressure. Do not exceed the rated working pressure or temperature range of this fitting.
