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

How a Fitting x Female NPT Flush Bushing Works
The larger male fitting end inserts directly into the female solder cup of a compatible copper fitting. The smaller female NPT outlet accepts a male threaded pipe or fitting. The fitting-end connection is soldered or brazed, while the threaded connection is assembled using an approved thread sealant suitable for the application.
Female NPT Flush Bushing vs. Copper Flush Bushing
Fitting x Female NPT Flush Bushing
- Uses one male fitting end and one female threaded outlet
- Transitions from a copper fitting socket to threaded pipe
- Creates a compact threaded reducing connection
- Useful for valves, gauges, equipment, and threaded components
Fitting x Copper Flush Bushing
- Uses one male fitting end and one female copper sweat socket
- Transitions from a larger fitting socket to smaller copper tube
- Maintains an all-soldered copper connection
- Does not provide a threaded outlet
Common Applications
Plumbing and Mechanical Systems
- Potable-water piping
- Residential plumbing systems
- Commercial plumbing installations
- Mechanical-room piping
- Heating-system piping
- Threaded valve connections
HVAC and Equipment Connections
- Air-conditioning piping
- Refrigeration systems
- Heat-pump installations
- Pressure-gauge connections
- Equipment and instrument connections
- Maintenance and retrofit work
Installation Guidance
- Confirm both the larger fitting-end size and smaller female NPT size before installation.
- Clean and prepare the fitting end and receiving copper fitting socket properly.
- Use approved flux, solder, brazing alloy, and joining procedures for the fitting-end connection.
- Insert the male fitting end fully into the receiving fitting socket before joining.
- Use an approved thread sealant or thread tape compatible with the system media and temperature.
- Thread the male component into the female NPT outlet without cross-threading or overtightening.
- Avoid applying excessive torque that could damage or distort the copper fitting.
- Protect nearby valves, seals, insulation, and equipment from excessive heat.
- Support connected piping and equipment 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 fitting x female NPT flush bushing used for?
It creates a compact reducing transition from a larger female copper fitting socket to a smaller female threaded connection.
What does fitting x female NPT mean?
The larger end is a male fitting end that inserts into a female copper fitting socket. The smaller end is a female NPT threaded outlet.
How are the sizes read?
The larger fitting-end size is listed first, followed by the smaller female NPT 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.
What connects to the female NPT outlet?
A properly sized male NPT pipe, nipple, valve, gauge, adapter, or other threaded component connects to the female threaded outlet.
How is this different from a fitting x copper flush bushing?
This fitting has a female NPT threaded outlet. A fitting x copper flush bushing has a female copper sweat socket instead.
Why is it called a flush bushing?
Its compact design allows the reducing transition to sit closely within the receiving copper fitting rather than extending like a standard adapter.
How is the fitting installed?
The fitting end is soldered or brazed into a compatible copper fitting socket. The female threaded outlet is assembled with an approved thread sealant and a male NPT component.
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 HVAC or mechanical piping?
It may be used in compatible HVAC and mechanical systems when the material, size, joining procedure, pressure, temperature, and system requirements are appropriate.
