Description
Copper Male Adapter - C x MPT
Charman Inc. Copper Male Adapters provide a transition from compatible copper tubing to a male threaded connection. The C x MPT configuration combines a copper cup connection with a male pipe thread for connecting copper piping to compatible female-threaded valves, fittings, equipment, and other piping components.
The cup side is designed for a solder / sweat joint with compatible copper tubing, while the threaded side provides a connection point for a compatible female-threaded component.

- C x MPT connection configuration
- Copper cup connection
- Male pipe thread connection
- Copper construction
- Solder / sweat connection on the copper side
- Threaded connection for compatible female-threaded components
- Straight transition between copper tube and threaded piping

What Is a Copper Male Adapter?
A copper male adapter transitions a copper tube piping system to a compatible female-threaded component. The cup end receives copper tubing while the external male threaded end installs into a mating female pipe thread.
- Transitions from copper tube to threaded piping
- Copper cup connection receives compatible tubing
- Male threaded connection installs into compatible female pipe thread
- Useful for valves, equipment, manifolds, and threaded fittings
- Provides both soldered and threaded connection methods in one fitting
Understanding C x MPT
C Connection
The cup-style connection receives compatible copper tubing and is joined using an appropriate solder / sweat installation method.
MPT Connection
The external male pipe thread installs into a compatible female-threaded valve, fitting, equipment port, manifold, or other piping component.
Male Adapter vs. Female Adapter
Male Adapter
Uses an external male pipe thread designed to install into a compatible female-threaded connection.
Female Adapter
Uses an internal female pipe thread designed to accept a compatible external male-threaded component.
Why Use a Copper Male Adapter?
Copper-to-Thread Transition
Provides a direct transition between a soldered copper tube system and a compatible threaded piping component.
Equipment Connections
Useful where copper tubing must connect to a female-threaded valve, equipment port, manifold, fitting, or other component.
Serviceable Connection
The threaded side provides a connection that can be disassembled when access to the mating component is required.
Common Applications
Plumbing & Mechanical
- Copper water piping
- Mechanical piping systems
- Valve connections
- Equipment connections
- Repair and maintenance
- Piping modifications
Threaded Transitions
- Female-threaded valves
- Female-threaded equipment ports
- Threaded fittings
- Manifold connections
- Utility piping connections
- Copper-to-threaded assemblies
How to Select the Correct Male Adapter
- Identify the nominal size of the copper tubing.
- Confirm that a male threaded connection is required.
- Verify that the mating component has a compatible female pipe thread.
- Confirm that a solder / sweat copper connection is appropriate for the tube side.
- Select the variation corresponding to the required connection size.
Installation Guidance
- Verify the copper tube and threaded connection sizes before installation.
- Inspect the copper cup and male threaded connection for damage or contamination.
- Cut compatible copper tubing squarely and remove burrs as appropriate.
- Clean the tubing and fitting cup before soldering.
- Apply appropriate flux according to the joining procedure.
- Protect the threaded end from excessive heat during soldering.
- Allow the soldered connection to cool before completing the threaded connection where practical.
- Use thread sealant appropriate for the piping application and mating threads.
- Avoid excessive tightening torque on the threaded connection.
- Test the completed piping system for leakage before placing it into service.

Our pipe and fitting specialists can help review your copper tube size, male thread requirements, mating female-threaded component, solder-joint installation, and piping application before you order.

What does C x MPT mean?
C identifies a cup-style connection designed to receive compatible copper tubing, while MPT means male pipe thread.
What is a copper male adapter used for?
It transitions a copper tube piping system to a compatible female-threaded valve, fitting, equipment port, manifold, or other piping component.
How is a male adapter different from a female adapter?
A male adapter has external male threads designed to install into a female-threaded connection. A female adapter has internal threads designed to accept a male-threaded component.
Is the copper side threaded?
No. The copper side is a cup-style connection designed to receive compatible copper tubing for a solder / sweat joint.
What can the MPT side connect to?
The MPT connection can install into a compatible female-threaded valve, fitting, equipment port, manifold, or other component with the appropriate pipe thread.
Should the threaded connection be protected while soldering?
Yes. Avoid exposing the threaded end or attached threaded components to unnecessary soldering heat, and follow appropriate installation procedures for the piping system.
Important Ordering Notes
- Verify the nominal copper tube size before ordering.
- Confirm that a male threaded connection is required.
- Verify that the mating component uses a compatible female pipe thread.
- Confirm that a C x MPT configuration is appropriate for the installation.
