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

What Is a Copper Female Adapter?
A copper female adapter transitions a copper tube piping system to a compatible male-threaded component. The cup end receives copper tubing while the female threaded end accepts a mating male pipe thread.
- Transitions from copper tube to threaded piping
- Copper cup connection receives compatible tubing
- Female threaded connection accepts compatible male pipe thread
- Useful for valves, equipment, nipples, and threaded fittings
- Provides both soldered and threaded connection methods in one fitting
Understanding C x FPT
C Connection
The cup-style connection receives compatible copper tubing and is joined using an appropriate solder / sweat installation method.
FPT Connection
The female pipe thread connection accepts a compatible male-threaded pipe, nipple, valve, fitting, or equipment connection.
Female Adapter vs. Male Adapter
Female Adapter
Uses an internal female pipe thread that accepts a compatible external male-threaded component.
Male Adapter
Uses an external male pipe thread designed to connect to a compatible female-threaded fitting, valve, or equipment port.
Why Use a Copper Female 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 terminate at a male-threaded valve, equipment port, nipple, 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
- Male-threaded valves
- Male-threaded equipment ports
- Threaded nipples
- Mechanical components
- Utility piping connections
- Copper-to-threaded assemblies
How to Select the Correct Female Adapter
- Identify the nominal size of the copper tubing.
- Confirm that the mating component requires a female-threaded adapter.
- Verify that the mating component has a compatible male 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 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, female thread requirements, mating male-threaded component, solder-joint installation, and piping application before you order.

What does C x FPT mean?
C identifies a cup-style connection designed to receive compatible copper tubing, while FPT means female pipe thread.
What is a copper female adapter used for?
It transitions a copper tube piping system to a compatible male-threaded valve, fitting, nipple, equipment port, or other piping component.
How is a female adapter different from a male adapter?
A female adapter has an internal female threaded connection that accepts male threads. A male adapter has external male threads designed to connect to a female-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 connect to the FPT side?
The FPT connection can accept a compatible male-threaded pipe, nipple, valve, fitting, equipment port, or other component with the appropriate pipe thread.
Should the threaded connection be assembled before soldering?
Installation sequence should account for heat exposure and access to the joint. Protect threaded components from excessive 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 female threaded connection is required.
- Verify that the mating component uses a compatible male pipe thread.
- Confirm that a C x FPT configuration is appropriate for the installation.
