Reducing Coupling Configuration
Larger Female NPT End
The larger threaded opening accepts a compatible male NPT pipe, nipple, fitting, valve, or equipment connection.
Reducing Body
The compact bronze body transitions between two different nominal pipe sizes within a single threaded fitting.
Smaller Female NPT End
The smaller threaded opening accepts the corresponding smaller male NPT piping component.
Construction Details
Midland Bronze Reducing Couplings are manufactured from high-quality cast bronze to provide dependable mechanical strength, corrosion resistance, and long service life in compatible piping systems.
Precision-machined female NPT threads on both ends provide consistent engagement with compatible male-threaded components.
The one-piece reducing configuration allows a direct transition between different nominal pipe sizes while minimizing the number of fittings required in the installation.
Why Choose a Bronze Reducing Coupling?
Direct Size Transition
- Connects two different pipe sizes
- Combines coupling and reducing functions
- Reduces the need for additional adapters
- Compact installation footprint
- Useful for repairs and system modifications
Bronze Construction
- Excellent corrosion resistance
- Dependable mechanical strength
- Suitable for compatible water systems
- Useful in commercial and industrial piping
- Designed for long-term service
Female NPT Connections
Larger Connection
The larger female NPT end connects to the corresponding larger male-threaded piping component.
Smaller Connection
The smaller female NPT end connects to the corresponding smaller male-threaded piping component to complete the size transition.
Typical Applications
Plumbing & Water Systems
- Potable water piping
- Residential plumbing
- Commercial plumbing
- Pipe size transitions
- Maintenance and repair
Commercial & Industrial
- General industrial piping
- Mechanical equipment connections
- Valve installations
- System modifications
- Compatible fluid handling systems
Size Selection
Midland Bronze Reducing Couplings are available in multiple reducing size combinations.
Verify both nominal pipe sizes before ordering. The larger and smaller female NPT openings must match the male-threaded components being connected.

Our pipe and fitting specialists can help review both pipe sizes, NPT compatibility, system media, pressure, temperature, and installation requirements before you order.

What is a reducing coupling used for?
It is used to connect two different nominal pipe sizes within a threaded piping system.
What material is this coupling made from?
It is manufactured from cast bronze.
What type of connections does it use?
It uses female NPT threaded connections on both ends.
What connects to the female NPT openings?
Compatible male NPT pipe, nipples, fittings, valves, or equipment connections can be installed into the coupling.
Why are the two ends different sizes?
The fitting is designed to transition directly between two different nominal pipe sizes.
What is the advantage over using multiple fittings?
A reducing coupling combines the connection and pipe-size transition into a single compact fitting.
Are multiple reducing sizes available?
Yes. The supplied product information identifies multiple reducing size combinations.
Should thread sealant be used?
Use an appropriate pipe-thread sealant or PTFE tape on NPT threaded connections according to the application requirements.
Can these be used for potable water?
The supplied product information identifies potable water and plumbing applications. Confirm the specific model meets the requirements of your installation before use.
What should I verify before ordering?
Confirm both nominal pipe sizes, male-thread compatibility, system pressure, temperature, media compatibility, and installation requirements.
Important Ordering & Installation Notes
- This listing is for Midland Bronze Reducing Couplings.
- The fitting uses female NPT threads on both ends.
- Verify both nominal reducing sizes before ordering.
- Confirm the mating components use compatible male NPT threads.
- The larger and smaller connection sizes are not interchangeable when selecting the required configuration.
- Use an appropriate thread sealant or PTFE tape on NPT connections.
- Start threaded connections carefully to help prevent cross-threading.
- Inspect all threads for damage, contamination, or debris before assembly.
- Avoid excessive tightening that could damage the coupling or mating components.
- Verify bronze is compatible with the intended system media.
- Confirm system pressure and temperature requirements before installation.
- Verify any potable-water requirements for the specific fitting selected.
- Check completed connections for leakage before placing the system into normal service.
- Pipe, nipples, valves, and additional fittings are sold separately unless otherwise specified.
- Install according to applicable piping requirements and Midland manufacturer recommendations.
