Description
Domestic Cleaned & Bagged Wrot Copper Reducing Coupling
Domestic cleaned and bagged wrot copper reducing couplings provide a straight transition between two different nominal copper tube sizes. Each fitting has female copper sweat sockets on both ends and is cleaned and bagged to help protect the joining surfaces before installation.

Cleaned & Bagged Construction
Each coupling is cleaned and enclosed in protective packaging to help preserve the condition of its internal and external joining surfaces during storage, transportation, and handling. Keep the fitting sealed in its original bag until it is ready for installation.
Cleaned and bagged copper fittings are commonly specified for piping systems where oils, dirt, grease, moisture, metal particles, and other contaminants must be carefully controlled. The installer is responsible for confirming that the fitting, cleaning level, packaging, joining method, and installation procedure satisfy the project specifications and applicable code requirements.
How a Copper Reducing Coupling Works
The larger female copper sweat socket fits over the larger copper tube, while the smaller female socket fits over the reduced copper tube size. Both tubes are fully inserted into their corresponding sockets and then soldered or brazed using the approved joining procedure.
Reducing Coupling vs. Standard Coupling
Reducing Coupling
- Connects two different copper tube sizes
- Has a larger female socket on one end
- Has a smaller female socket on the other end
- Creates a compact straight-line size transition
Standard Coupling
- Connects two equal-size copper tubes
- Uses the same socket size on both ends
- Maintains one nominal tube size
- Does not reduce the piping diameter
Common Applications
Clean and Controlled Piping
- Medical-gas piping installations
- Laboratory piping systems
- Institutional piping projects
- Clean mechanical piping
- Process piping requiring protected fittings
- Projects specifying cleaned and bagged copper components
Copper Pressure-Piping Systems
- Commercial plumbing systems
- Heating and cooling piping
- HVAC and refrigeration systems
- Equipment connections
- Branch and equipment size transitions
- Maintenance and retrofit work
Installation Guidance
- Confirm both required nominal copper tube sizes before ordering.
- Size descriptions list the larger connection first and the smaller connection second.
- Verify that cleaned and bagged fittings meet the project specifications.
- Keep the fitting sealed until immediately before installation.
- Handle the fitting with 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 sockets and copper tube ends before assembly.
- Prepare all joining surfaces using approved procedures and materials.
- Insert each copper tube fully into its corresponding socket.
- Use approved solder, brazing alloy, purge gas, flux, and joining procedures.
- Follow applicable medical-gas requirements when installed in medical-gas systems.
- Support the connected piping to prevent strain on completed joints.
- Pressure-test and inspect the completed system before placing it into service.

Frequently Asked Questions
What is a cleaned and bagged copper reducing coupling?
It is a straight wrot copper fitting that joins two different nominal copper tube sizes and is cleaned and enclosed in protective packaging before shipment.
Are both connections female copper sockets?
Yes. Both ends are female copper sweat sockets designed to fit over the corresponding copper tube sizes.
Which size is listed first?
The larger nominal copper tube connection is listed first, followed by the smaller reducing connection.
Is this an equal-size coupling?
No. This fitting connects two different nominal copper tube sizes. Equal-size couplings are offered separately.
Why is the fitting supplied in a bag?
The protective bag helps prevent dirt, grease, moisture, metal particles, and other contaminants from contacting the fitting before installation.
When should the fitting be removed from its bag?
Keep it sealed until immediately before installation or as directed by the approved project procedure.
Can this reducing coupling be brazed?
Yes, when brazing is appropriate for the application and completed using approved materials, purge requirements, procedures, and applicable codes.
Can this reducing coupling be soldered?
It may be soldered when permitted by the application, project specification, and applicable code.
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 a medical-gas system?
It may be used when the fitting, packaging, cleaning level, material, joining method, and installation procedure satisfy the project specifications and applicable code requirements.
Can the fitting be used if the bag is damaged?
Do not assume that a damaged or opened package still meets project cleanliness requirements. Follow the applicable contamination-control and rejection procedures.
Does the selected size determine the SKU and price?
Yes. Each reducing combination has its own Cello SKU, online selling price, estimated shipping weight, and cost.
Important Ordering Notes
- Select the required larger and smaller copper tube sizes before adding the product to your cart.
