Description
Domestic Cleaned & Bagged Wrot Copper Slip Coupling – No Stop
Domestic cleaned and bagged wrot copper slip couplings provide a straight, equal-size connection between two sections of copper tube without an internal tube stop. The no-stop design allows the coupling to slide completely over the copper tube, making it useful for repairs, alignment adjustments, and installations where the pipe ends cannot be moved apart.
Select the required nominal copper tube size from the product options above. The selected variation determines the Cello item number, online selling price, shipping weight, cost, and other size-specific information.

How a No-Stop Slip Coupling Works
Unlike a standard coupling, this fitting has no internal stop. The coupling can slide completely onto one section of copper tube, allowing the second tube to be positioned in line. The coupling is then moved back across both tube ends before the joints are soldered or brazed using the approved installation procedure.
Slip Coupling vs. Standard Coupling
No-Stop Slip Coupling
- Has no internal tube stop
- Can slide completely over the copper tube
- Useful when pipe ends cannot be spread apart
- Commonly used for repairs and retrofit work
Standard Coupling
- Contains an internal tube stop
- Positions each tube end near the center
- Requires tube insertion from both ends
- Commonly used for new straight-run installations
Cleaned & Bagged Construction
Each fitting is cleaned and enclosed in protective packaging to help preserve the condition of its joining surfaces during storage, transportation, and handling. Keep the fitting sealed in its original bag until immediately before installation.
Cleaned and bagged copper fittings are commonly specified for piping systems where dirt, oil, grease, moisture, metal particles, and other contaminants must be controlled. Confirm that the fitting, cleaning level, packaging, joining method, and installation procedures meet the project specifications and applicable code requirements.
Common Applications
Repair and Retrofit Work

- Commercial plumbing systems
- Projects specifying cleaned and bagged copper components
Installation Guidance
- Confirm the required nominal copper tube size before ordering.
- Verify that a no-stop slip coupling is appropriate for the installation.
- 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 its protective package is damaged or it appears contaminated.
- Clean, deburr, and prepare both copper tube ends according to the approved procedure.
- Mark the intended final coupling position on the copper tube before assembly.
- Slide the coupling completely over one tube before aligning the second tube.
- Center the coupling evenly across both tube ends before joining.
- Confirm that both tube ends extend sufficiently into the coupling.
- Use approved solder, brazing alloy, purge gas, flux, and joining procedures.
- Follow applicable medical-gas requirements when installed in medical-gas piping.
- Support the 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 no-stop copper slip coupling?
It is a straight copper coupling without an internal tube stop, allowing the fitting to slide completely over properly sized copper tube.
What is a slip coupling used for?
It is commonly used for copper pipe repairs, retrofit work, alignment corrections, and installations where the two pipe ends cannot be moved apart.
Are both connections female copper sockets?
Yes. Both ends are female copper sweat sockets designed to fit over equal-size copper tube.
How is this different from a standard coupling?
A standard coupling contains an internal stop. A slip coupling has no stop and can slide completely over the tube.
How do I center the coupling over the repair?
Mark the intended final position on the copper tube before assembly, then slide the coupling back until it is evenly positioned across both tube ends.
Is this a reducing coupling?
No. Both connections use the same nominal copper tube size.
Why is the fitting cleaned and bagged?
The protective packaging helps prevent dirt, grease, moisture, metal particles, and other contaminants from contacting the fitting before installation.
Can this slip coupling be brazed?
Yes, when brazing is appropriate for the application 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.
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.
