Description
Copper Cap
Charman Inc. Copper Caps are designed to close and terminate the end of compatible copper tubing in soldered piping systems. The cup-style connection slips over the end of the copper tube and is joined using a solder / sweat installation method.
This compact closed-end fitting is useful for permanent tube terminations, closing unused branches, piping modifications, and creating planned termination points within copper piping systems.

What Is a Copper Cap?
A copper cap is a closed-end fitting used to terminate compatible copper tubing. The open cup end receives the tube while the opposite end remains closed, creating an end point in the piping run after the connection is properly soldered.
- Closes the end of compatible copper tubing
- Uses a single cup-style connection
- Provides a compact piping termination
- Useful for unused branches and planned termination points
- Designed for solder / sweat joining
Why Use a Copper Cap?
Terminate a Tube Run
Provides a straightforward way to close the end of a copper piping run where no additional connection is required.
Close an Unused Branch
Can terminate a copper branch that is no longer needed as part of a repair, renovation, or piping modification.
Planned Termination
Provides a defined termination point for piping layouts that may be modified or extended during future system work.
Understanding the Cup Connection
The open end of the cap uses a cup-style connection designed to fit over compatible copper tubing. The prepared tube end is inserted fully into the fitting cup and joined using an appropriate solder / sweat procedure.
Common Applications
Plumbing & Mechanical
- Copper water piping
- Mechanical piping systems
- Equipment piping
- Service piping
- Repair and maintenance
- Piping modifications
Tube Termination
- Closing unused copper branches
- End-of-line piping termination
- Planned expansion points
- Fabricated copper assemblies
- Mechanical room piping
- Renovation and retrofit work
How to Select the Correct Copper Cap
- Identify the nominal size of the copper tubing being terminated.
- Confirm that the piping run requires a closed-end fitting.
- Verify that a cup-style connection is appropriate for the tubing.
- Confirm that solder / sweat joining is appropriate for the piping system.
- Select the cap that matches the nominal copper tube size.
Installation Guidance
- Verify the nominal copper tube size before installation.
- Confirm the piping system is properly isolated and prepared for the work.
- Cut compatible copper tubing squarely.
- Remove internal and external burrs as appropriate.
- Clean the tube end and fitting cup before soldering.
- Apply appropriate flux according to the joining procedure.
- Fully seat the cap over the end of the copper tube.
- Use proper soldering and heating procedures for copper joints.
- Allow the completed joint to cool before disturbing the assembly.
- Test the completed piping system for leakage before placing it into service.
Our pipe and fitting specialists can help review your copper tube size, termination requirements, solder-joint connection, piping layout, and application before you order.

What is a copper cap used for?
A copper cap is used to close and terminate the end of compatible copper tubing.
How does a copper cap connect to the tubing?
The open cup end fits over compatible copper tubing and is joined using an appropriate solder / sweat procedure.
Can a copper cap be used to close an unused branch?
Yes. A properly sized and installed copper cap can terminate an unused compatible copper tube branch.
Can a capped branch be extended later?
A capped branch may be modified during future piping work, but the existing cap must be properly removed and the piping prepared for the new connection before an extension is installed.
Is a copper cap threaded?
No. This cap uses a cup-style connection designed to fit over compatible copper tubing for solder / sweat joining.
Is this a permanent piping connection?
A soldered copper cap creates a fixed piping termination. Future changes require the piping to be safely isolated and the capped section modified or removed as appropriate.
Important Ordering Notes
- Verify the nominal copper tube size before ordering.
- Confirm that a closed-end cap is appropriate for the piping layout.
- Verify that a cup-style solder / sweat connection is required.
- Confirm the cap will be used with compatible copper tubing and the appropriate joining procedure.
