Midland Copper Solder Joint Union - C x C

Product Highlights

• Midland copper union
• C x C connection configuration
• Copper solder-joint / sweat connections
• Removable three-piece union design
• Allows piping sections to be disconnected for service
• Standard non-LF configurations
• Sizes from 1/2" through 2"
• Five configurations on one listing
• Designed for compatible copper tube piping systems

A copper union creates a connection that can later be separated without cutting the copper tube. The fitting joins two sections of piping while providing a mechanical connection point between the soldered ends.

• Allows piping sections to be separated for maintenance
• Useful near serviceable equipment and components
• Both ends connect to compatible copper tubing
• Soldered ends remain attached to the piping
• Union connection can be disassembled when service is required

C x C indicates that both piping connections are cup-style connections designed to receive compatible copper tube.

• First C: copper tube connection
• Second C: copper tube connection
• Both sides use solder-joint installation
• Both connections use the same nominal size

The copper ends of the union are intended for solder-joint installation with compatible copper tubing.

• Confirm fitting and tube size before installation.
• Cut copper tubing squarely.
• Remove internal and external burrs.
• Clean the tube ends and fitting sockets thoroughly.
• Use joining materials appropriate for the piping application.
• Insert tubing fully into each cup connection.
• Solder each side using appropriate procedures.
• Avoid overheating the union's removable connection components.

• Near pumps and other serviceable equipment
• Adjacent to valves or control components
• At equipment connections that may require replacement
• Where future piping disassembly is anticipated
• In maintenance-sensitive mechanical piping systems

• Step 1: Identify the nominal copper tube size.
• Step 2: Confirm that a C x C solder-joint union is required.
• Step 3: Select the matching nominal size.
• Step 4: Confirm adequate access will remain around the union for future service.
• Step 5: Verify the fitting and joining method are appropriate for the piping application.

• Verify fitting and copper tube size before installation.
• Disassemble or protect heat-sensitive union components as appropriate during soldering.
• Clean all copper mating surfaces thoroughly.
• Insert tubing completely into each cup connection.
• Use appropriate soldering materials and procedures.
• Allow soldered connections to cool before final union assembly.
• Align piping before tightening the union connection.
• Avoid using the union to pull misaligned piping together.
• Pressure-test the completed piping system according to applicable requirements.
