How a C x C Copper Union Works
A copper union connects two sections of copper tube with female sweat sockets on both ends. Each socket fits over properly sized copper tube and is soldered or brazed using an approved joining method. The center union nut can then be loosened to separate the piping connection without cutting the copper tube, making the fitting useful where equipment, valves, piping sections, or system components may require future service or replacement.
Copper Union vs. Standard Coupling
C x C Copper Union
- Female copper sweat socket on both ends
- Fits over copper tube
- Center union nut allows disconnection and reconnection
- Useful where future service or removal may be required
C x C Copper Coupling
- Female copper sweat socket on both ends
- Fits over copper tube
- Creates a permanent inline connection after joining
- Typically requires cutting the piping to remove the connection
Cleaned & Bagged Construction
Each union is cleaned and enclosed in protective packaging to help preserve the condition of the copper joining surfaces during storage, transportation, and handling. Keep the fitting sealed in its original bag until immediately before installation.
Cleaned and bagged copper components are commonly specified for piping systems where dirt, oil, grease, moisture, metal particles, and other contaminants must be controlled. Confirm that the selected fitting, cleaning level, packaging, joining procedure, and installation method satisfy the project specifications and applicable codes.
Common Applications
Clean and Controlled Piping
- Medical-gas piping installations
- Laboratory piping systems
- Institutional piping projects

- Process piping requiring protected fittings
- Projects specifying cleaned and bagged copper components
Serviceable Copper Connections
- Equipment connections
- Valve and component isolation points
- Mechanical piping systems
- Commercial plumbing systems
- Maintenance and retrofit work
- Locations where future disassembly may be required
Installation Guidance
- Confirm the required nominal size before ordering.
- Verify that both copper union sockets are compatible with the copper tube size being installed.
- Keep the fitting sealed until immediately before installation.
- Handle the fitting using clean gloves and approved tools when required.
- Do not use the fitting if the protective package is damaged or the fitting appears contaminated.
- Inspect both copper sweat sockets and the union sealing surfaces before assembly.
- Clean and prepare the copper tube and union sockets using approved procedures.
- Insert the copper tube fully into each union socket.
- Use approved solder, brazing alloy, purge gas, flux, and joining procedures as required by the application.
- Protect the union sealing surfaces and center nut from excessive heat during soldering or brazing.
- Allow the joints to cool before final union assembly or tightening.
- Align the union halves properly before tightening the center nut.
- Do not force misaligned piping together with the union nut.
- Follow applicable medical-gas procedures when installed in medical-gas piping.
- Pressure-test and inspect the completed installation before placing it into service.

Frequently Asked Questions
What is a C x C wrot copper union?
It is a straight copper fitting with female copper sweat sockets on both ends and a center union connection that allows the piping to be separated and reconnected without cutting the copper tube.
What does C x C mean?
C x C identifies female copper sweat sockets on both ends of the union. Each socket fits over properly sized copper tube.
Does this union fit over copper tube?
Yes. Both ends are female copper sweat sockets designed to fit over properly sized copper tube.
Why use a union instead of a coupling?
A union allows the piping connection to be separated and reconnected by loosening the center union nut. A standard coupling creates a more permanent inline connection and normally requires cutting the piping for removal.
Can this copper union be brazed?
Yes, when brazing is appropriate and completed using approved materials, procedures, purge requirements, heat-control methods, and applicable codes.
Can this copper union be soldered?
It may be soldered when permitted by the application, project specifications, and applicable codes.
Should the union be assembled while brazing?
Follow the approved installation procedure for the specific system. Protect the union sealing surfaces and center connection from excessive heat, and allow the joined sections to cool before final assembly or tightening.
Why is this fitting cleaned and bagged?
The protective packaging helps prevent dirt, grease, oil, moisture, metal particles, and other contaminants from contacting the fitting before installation.
Is this a domestic copper fitting?
Yes. It is listed as a domestic cleaned and bagged wrot copper fitting manufactured by Cello Products.
Can it be used in medical-gas piping?
It may be used when the fitting, cleaning level, packaging, joining procedure, installation method, and completed system satisfy the project specifications and applicable medical-gas requirements.
What sizes are available?
This product is available in nominal sizes from 1/4" through 4". Select the required size from the product options above.
