Midland Industries 77241 Solder Joint Coupling 1 in Copper

Product Description

The MIDLAND INDUSTRIES 77241 is a wrot copper solder joint coupling with a dimpled tube stop, designed for joining 1-inch copper tubing in pressure piping systems. The dimpled tube stop centers the pipe inside the fitting and controls insertion depth, ensuring consistent solder joint alignment. Rated to 500 psi with a working temperature range of 32 to 200 degrees F, this coupling suits domestic water supply, hydronic heating, and general plumbing distribution lines. Both ends accept 1-inch C (sweat) connections. Plumbers and pipefitters install this fitting as a standard in-line union for copper tubing runs in residential and light commercial construction.

This coupling is used wherever a straight, in-line connection is needed between two sections of 1-inch copper tubing. Typical applications include potable water supply lines, recirculation loops, and hydronic radiant or baseboard heating systems. The wrot copper construction provides the wall thickness and grain structure preferred for soldered pressure fittings in code-compliant plumbing work. It is suited for both new construction and repair or replacement of existing copper piping.

Key Features

• Dimpled tube stop controls pipe insertion depth for consistent, repeatable solder joints
• Wrot copper construction for high-integrity soldered connections under pressure
• 500 psi pressure rating supports standard residential and light commercial plumbing service
• Operating temperature range of 32 to 200 degrees F covers typical hot and cold water applications
• 1 in C x 1 in C sweat connections on both ends

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 1-inch copper sweat (C) pressure piping systems in residential and commercial plumbing applications.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC or local plumbing code requirements. Shut off and drain the water supply before cutting or soldering any section of the piping system. Clean all pipe ends and fitting interiors with emery cloth and apply flux before soldering per ASTM B828 procedures. Allow completed joints to cool fully before restoring system pressure.
