Description
Domestic Wrot Copper Fitting x Copper Flush Bushing
Domestic wrot copper fitting x copper flush bushings reduce a larger female copper fitting socket to a smaller copper-tube connection while maintaining a compact, flush-profile installation. The larger male fitting end inserts directly into a compatible copper fitting socket, and the smaller female copper sweat socket accepts properly sized copper tube.
Select the required reducing size from the product options above. Sizes are listed as the larger fitting-end size first and the smaller copper sweat size second. The selected variation determines the Cello item number, online selling price, shipping weight, cost, and other size-specific product information.

How a Copper Flush Bushing Works
The larger male fitting end inserts directly into the female solder cup of a compatible copper fitting. The smaller female copper sweat socket accepts properly sized copper tube. After all joining surfaces are cleaned and prepared, the connections are assembled with approved flux and soldered or brazed to create a compact reducing transition.
Flush Bushing vs. Reducing Coupling
Flush Bushing
- Uses one male fitting end and one female copper sweat socket
- Inserts directly into a larger copper fitting socket
- Creates a compact reducing transition
- Helps minimize overall installed length
Reducing Coupling
- Uses female copper sweat sockets on both ends
- Fits over two different copper-tube sizes
- Connects larger and smaller copper-tube runs
- Requires tube insertion on both sides
Common Applications
Plumbing and Mechanical Systems
- Potable-water piping
- Residential plumbing systems
- Commercial plumbing installations
- Mechanical-room piping
- Heating-system piping
- Copper distribution piping
HVAC and Equipment Connections
- Air-conditioning piping
- Refrigeration systems
- Heat-pump installations
- Equipment connections
- Compact reducing transitions
- Maintenance and retrofit work
Installation Guidance
- Confirm both the larger fitting-end size and smaller copper-tube size before installation.
- Clean and prepare the fitting end, receiving fitting socket, copper tube end, and sweat socket properly.
- Use approved flux, solder, brazing alloy, and joining procedures for the application.
- Insert the male fitting end fully into the receiving fitting socket.
- Insert the smaller copper tube fully into the female sweat socket.
- Align the connected piping and fittings correctly before heating the joints.
- Protect nearby valves, seals, insulation, and equipment from excessive heat.
- Support connected piping and fittings to avoid mechanical strain on the bushing.
- Pressure-test and inspect completed joints before placing the system into service.

Frequently Asked Questions
What is a copper flush bushing used for?
It reduces a larger female copper fitting socket to a smaller copper-tube connection in a compact installation.
What does fitting x copper mean?
The larger end is a male fitting end that inserts into a female copper fitting socket. The smaller end is a female copper sweat socket that fits over copper tube.
How are the sizes read?
The larger fitting-end size is listed first, followed by the smaller copper-sweat size.
Does the fitting end go inside another copper fitting?
Yes. The male fitting end inserts directly into a properly sized female copper fitting socket.
Does the smaller end fit over copper tube?
Yes. The smaller female copper sweat socket fits over properly sized copper tube.
How is this different from a reducing coupling?
A flush bushing has one male fitting end and one female copper sweat socket. A reducing coupling has female copper sweat sockets on both ends.
Why is it called a flush bushing?
Its compact design allows the reducing connection to sit closely within the receiving fitting rather than extending like a standard reducing coupling.
How is the flush bushing installed?
The joining surfaces are cleaned, prepared with approved flux, assembled, and soldered or brazed according to accepted procedures and applicable codes.
Is this a domestic copper fitting?
Yes. This product is listed as a domestic wrot copper pressure fitting.
Who manufactures this flush bushing?
This product is manufactured by Cello Products.
Can it be used in potable-water systems?
It may be used in compatible potable-water systems when installed according to applicable codes, standards, manufacturer requirements, and approved joining procedures.
Can it be used for refrigeration or HVAC piping?
It may be used in compatible HVAC and refrigeration systems when the material, size, joining procedure, pressure, temperature, and system requirements are appropriate.
Important Ordering Notes
