Midland Industries 77222 Solder Joint Coupling 1/2 in Copper

Product Description

The MIDLAND INDUSTRIES 77222 is a wrot copper solder joint coupling without a tube stop, designed for sweat-soldered connections in residential and commercial plumbing systems. The fitting accepts 1/2-inch copper tubing on both ends using standard C x C (sweat) connections. Without a tube stop, the pipe can slide fully through the coupling, which is useful when making repairs on existing runs where a tube stop would obstruct seating. Rated to 500 psi and suitable for operating temperatures from 32 degrees F to 200 degrees F, this fitting is built for reliable pressure service in water supply and hydronic applications.

This coupling is used in residential and light commercial plumbing installations wherever a 1/2-inch copper supply or distribution line requires joining, extending, or repairing. The no-tube-stop design is particularly suited to in-line repair work where the technician needs full pipe travel through the fitting before soldering. Licensed plumbers and pipefitters install this fitting using standard sweat-soldering techniques on copper water supply lines, radiant heating distribution, and similar piping systems.

Key Features

• Wrot copper construction for durability and reliable soldered joints
• No tube stop allows full pipe travel through the fitting for repair applications
• 1/2 inch C x 1/2 inch C connections for standard sweat-solder assembly
• Rated to 500 psi for pressure service applications
• Operating temperature range of 32 degrees F to 200 degrees F
• Compact profile at approximately 1.05 inches in length

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 1/2-inch copper tubing in sweat-soldered plumbing and hydronic systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off and drain the water supply line before cutting or fitting any pipe. Clean and flux all mating surfaces before applying heat, and allow joints to cool fully before restoring pressure. Do not substitute this fitting in gas line applications.
