A copper coupling with stop is a straight fitting used to join two sections of compatible copper tube of the same nominal size. An internal stop provides a positioning point for the tube ends during assembly.

• Joins two equal-size sections of copper tubing
• Provides a straight inline connection
• Internal stop assists with tube positioning
• Both ends use cup-style solder connections
• Designed for permanent solder-joint installations

The internal stop provides a physical positioning point inside the coupling. During installation, each section of tubing is inserted into its respective side of the coupling until it reaches the stop.

• Helps establish proper tube insertion
• Helps position opposing tube ends
• Simplifies alignment during standard installation
• Provides a repeatable insertion point
• Distinguishes this fitting from a no-stop repair coupling

C x C indicates that both ends of the coupling are cup-style connections intended to receive compatible copper tube.

• First C: copper tube cup connection
• Second C: copper tube cup connection
• Same nominal size on both ends
• Straight-through configuration
• Solder-joint / sweat installation

Proper preparation of the copper tubing and fitting is important when making a solder-joint connection.

• Confirm the nominal fitting and tube size before installation.
• Cut copper tubing squarely.
• Remove internal and external burrs.
• Clean the tube ends and coupling sockets.
• Apply joining materials appropriate for the piping application.
• Insert each tube to the internal stop.
• Heat the joint using appropriate soldering procedures.
• Allow the completed connection to cool naturally.
• Inspect and test the completed piping system before service.

• Step 1: Determine the nominal size of the copper tubing.
• Step 2: Confirm both tube sections are the same nominal size.
• Step 3: Confirm a standard coupling with an internal stop is required.
• Step 4: Select the corresponding Midland part number.
• Step 5: Verify solder-joint installation is suitable for the application.

• Verify the coupling size matches the copper tubing before beginning installation.
• Prepare both tube ends properly before soldering.
• Insert each tube fully to the coupling's internal stop.
• Keep the piping aligned while completing the connection.
• Use soldering materials and procedures suitable for the piping system.
• Provide appropriate piping support, particularly for larger sizes.
• Do not place unnecessary mechanical stress on the completed joint.
• Pressure-test the completed system according to applicable requirements before placing it into service.
