Description
Lead-Free Brass Reducing Coupling FIP x FIP
Lead-Free Brass Reducing Couplings provide a straight female-to-female threaded transition between two different pipe sizes. The fitting features female pipe threads on both ends, allowing compatible male-threaded components of different nominal sizes to be joined in one compact inline connection.
Lead-free brass construction provides durability and corrosion resistance for compatible potable-water, plumbing, agricultural, construction, industrial, water-transfer, and general fluid-handling applications where lead-free components are required.

Construction Details
The fitting features a durable lead-free brass body with female pipe-thread connections on both ends.
The two female threaded openings are sized differently, allowing the coupling to transition between compatible male-threaded piping components of different nominal sizes.
The straight-through body maintains the direction of the piping run while providing the required size reduction in one compact threaded fitting.
Connection Configuration
Larger FIP Connection
The larger female pipe-thread connection accepts a compatible larger male-threaded pipe, nipple, valve, adapter, or other piping component.
Smaller FIP Connection
The smaller female pipe-thread connection accepts a compatible smaller male-threaded component to complete the reducing transition.
How a Reducing Coupling Works
A FIP x FIP reducing coupling joins two compatible male-threaded piping components of different sizes along the same straight piping path.
An appropriate thread-sealing method should be applied to the mating male pipe threads before each component is installed into the coupling.
Once assembled, the fitting provides a compact transition between the larger and smaller threaded pipe sizes without changing the direction of the piping run.

Reducing Coupling Design
Female-to-Female Reduction
Female pipe threads on both ends allow compatible male-threaded components of different sizes to be joined directly through the fitting.
Straight-Through Configuration
The coupling maintains a straight piping path while reducing the connection size between the two ends.
Reducing Coupling vs. Standard Coupling
Reducing Coupling
FIP x FIP - Different Sizes
A reducing coupling connects compatible male-threaded components of different nominal pipe sizes.
Standard Coupling
FIP x FIP - Same Size
A standard coupling generally joins two compatible male-threaded components of the same nominal pipe size.

Lead-Free Brass Benefits
Lead-free brass provides durable construction and corrosion resistance for compatible plumbing and fluid-handling systems where lead-free fitting materials are required.
The one-piece reducing coupling design provides a convenient way to transition between different threaded pipe sizes while maintaining a compact inline connection.
Installation & Selection Considerations
- Confirm both FIP connection sizes before ordering.
- Verify both mating components use compatible male pipe threads.
- Use a thread-sealing method suitable for brass fittings and the intended media.
- Avoid excessive tightening that could damage the coupling or mating threads.
- Verify pressure, temperature, media, and lead-free application requirements before installation.

Frequently Asked Questions
What is a Lead-Free Brass Reducing Coupling?
It is a straight female-to-female threaded fitting used to connect compatible male-threaded components of different nominal pipe sizes.
What does FIP x FIP mean?
FIP x FIP means both ends of the coupling use female pipe-thread connections.
Why is this called a reducing coupling?
The two female threaded ends are different sizes, allowing the fitting to transition between larger and smaller compatible threaded piping components.
Does this fitting change the direction of the piping?
No. A reducing coupling provides a straight-through inline connection.
What connects to this coupling?
Compatible male-threaded pipe, nipples, valves, adapters, and other piping components can connect to the two female-threaded ends.
What material is this coupling made from?
This reducing coupling features lead-free brass construction.
Should thread sealant be used?
Use a thread-sealing method appropriate for brass pipe-thread connections, the transferred media, and the requirements of the piping system.
Where can I find additional fitting information?

Important Ordering & Installation Notes
- Connection configuration is FIP x FIP.
- The two female threaded ends are different sizes for reducing service.
- Confirm both mating male-threaded connection sizes before ordering.
- Use an appropriate thread-sealing method and avoid overtightening.
- Verify lead-free, pressure, temperature, and media requirements before use.
