Description
125# Leaded Brass Reducing Coupling
125# Leaded Brass Reducing Couplings are threaded fittings designed to join two compatible male-threaded piping components of different nominal sizes in a straight piping run. The reducing configuration combines an in-line connection and size transition in one compact fitting.
This product is identified as a 125# leaded brass fitting. Manufacturer dimensional, certification, and material safety documentation is provided below for reference.

Reducing Coupling Construction
A reducing coupling provides female-threaded connections of different nominal sizes at each end, allowing two compatible male-threaded pipes, nipples, or fittings to be joined in a straight line.
The fitting transitions directly from the larger connection size to the smaller connection size without changing the direction of the piping run.
This configuration can simplify installations by combining the coupling and size reduction into one threaded fitting.
Why Choose a Reducing Coupling?
Straight-Line Size Transition
- Connects two different nominal pipe sizes
- Maintains a straight piping run
- Provides female threaded connections on both ends
- Combines connection and reduction in one fitting
- Useful in compact threaded piping layouts
Threaded Brass Construction
- Brass fitting body
- Leaded material
- Female x female threaded design
- Suitable for compatible piping applications
- Manufacturer documentation provided below
Reducing Coupling vs. Standard Coupling
Reducing Coupling
- Uses different nominal sizes at each end
- Connects two different pipe sizes
- Provides a straight-line size transition
- May eliminate a separate reducer
- This product configuration
Standard Coupling
- Typically uses the same nominal size on both ends
- Joins two same-size male-threaded components
- Maintains a straight piping run
- Does not change pipe size
- Different configuration from a reducing coupling
Common Applications
Plumbing & Mechanical Piping
- Threaded piping systems
- Pipe size transitions
- Equipment connections
- Utility piping
- General plumbing assemblies
Industrial & General Service
- Mechanical piping installations
- Maintenance and repair work
- Compatible process piping
- Equipment piping transitions
- Applications requiring an in-line threaded reduction
Installation & Selection Guidance
- Confirm both required nominal connection sizes before ordering.
- Verify which side of the coupling requires the larger and smaller connection.
- Confirm female thread compatibility with both mating male-threaded components.
- Verify that the straight reducing configuration matches the intended piping layout.
- Use an appropriate thread sealant for the system media, pressure, and temperature.
- Apply thread sealant according to the sealant manufacturer's instructions.
- Use appropriate wrenching surfaces during installation.
- Avoid over-tightening threaded fittings.
- Support connected piping as required to avoid excessive load on the coupling.
- Confirm pressure, temperature, and media compatibility before use.
- Verify that leaded brass is permitted for the intended application.
- Installation should comply with applicable piping, plumbing, and project requirements.

Frequently Asked Questions
What is a reducing coupling used for?
A reducing coupling is used to join two compatible male-threaded piping components of different nominal sizes in a straight piping run.
How is a reducing coupling different from a standard coupling?
A reducing coupling uses different nominal connection sizes at each end, while a standard coupling typically uses the same nominal size on both ends.
Does a reducing coupling change pipe direction?
No. It provides a straight in-line transition between two different pipe sizes.
Can a reducing coupling replace a coupling and reducer?
In compatible piping layouts, yes. It combines the straight connection and size reduction in a single fitting.
What material is this fitting?
The supplied product information identifies this fitting as leaded brass.
What pressure class is this fitting?
The product is identified as a 125# fitting.
Is this fitting lead free?
No. The supplied product information identifies this fitting as leaded.
