Cleaned & Bagged Construction
Each fitting is cleaned and enclosed in protective packaging to help preserve the condition of the 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 systems where dirt, oil, grease, moisture, metal particles, and other contaminants must be carefully controlled. Confirm that the selected product and cleaning level satisfy the project specifications and applicable code requirements.
How a Copper Coupling Works
Each end contains a female copper sweat socket. Properly sized copper tube is inserted into both sockets until it reaches the internal stop. The connections are then soldered or brazed using the approved joining procedure for the system.
Stop Configurations
Standard Coupling
- Provides a straight equal-size connection
- Uses an internal stop to position the copper tube
- Female copper sockets on both ends
- Used for most listed sizes
Ring-Stop Coupling
- Uses a formed internal ring to position the tube
- Provides a continuous internal stop
- Listed for the 2-1/2", 3", and 4" sizes
- Confirm the selected size before ordering

Installation Guidance
- Confirm the required nominal copper tube size before ordering.
- Verify that cleaned and bagged fittings satisfy the project specifications.
- Keep the fitting sealed until immediately before installation.
- Handle the fitting using clean gloves and approved tools when required.
- Do not use a fitting if the protective package is damaged or the fitting appears contaminated.
- Inspect both sockets and the copper tube ends before assembly.
- Prepare all joining surfaces using approved procedures.
- Insert both copper tubes fully into the coupling.
- Use approved solder, brazing alloy, purge gas, flux, and joining procedures.
- Follow applicable medical-gas requirements when used in medical-gas systems.
- Support connected piping to prevent strain on the completed joints.
- Pressure-test and inspect the completed system before placing it into service.

Frequently Asked Questions
What is a cleaned and bagged copper coupling?
It is a straight wrot copper coupling that has been cleaned and enclosed in protective packaging to help preserve its condition before installation.
What is this coupling used for?
It joins two equal-size sections of copper tube in a straight line.
Are both ends female copper sockets?
Yes. Both ends are female copper sweat sockets designed to fit over properly sized copper tube.
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 coupling be brazed?
Yes, when brazing is appropriate and completed using approved materials, procedures, purge requirements, and applicable codes.
Can this coupling be soldered?
It may be soldered when permitted by the application, project specification, and applicable code.
What is a ring-stop coupling?
A ring-stop coupling uses a continuous formed internal ring to position the inserted copper tube.
Which sizes are ring-stop couplings?
The listed 2-1/2", 3", and 4" variations use ring-coupling SKUs.
Is this a reducing coupling?
No. Both connection ends use the same nominal size.
Is this a domestic copper fitting?
Yes. It is listed as a domestic cleaned and bagged wrot copper fitting manufactured by Cello Products.
Can this fitting be used in medical-gas piping?
It may be used when the fitting, packaging, cleaning level, material, joining method, and installation procedure satisfy the project specifications and applicable code requirements.
