Description
Lead-Free Brass FIP x FIP Coupling
Lead-Free Brass FIP x FIP Couplings provide a straight female-to-female threaded connection for joining two compatible male-threaded pipe, nipples, adapters, valves, or other piping components. The coupling features female pipe threads on both ends for an inline connection between compatible components.
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 coupling features a durable lead-free brass body with female pipe-thread connections at both ends.
The straight-through body allows compatible male-threaded pipe, nipples, valves, adapters, and other piping components to be joined in an inline configuration.
The simple two-port design makes the coupling useful for extending threaded piping runs, joining sections of pipe, and connecting compatible components without changing the direction of the piping system.
Connection Configuration
Female Pipe Thread - Side 1
The first female pipe-thread connection accepts a compatible male-threaded pipe, nipple, valve, adapter, or other piping component.
Female Pipe Thread - Side 2
The opposite female pipe-thread connection accepts the second compatible male-threaded component to complete the straight inline connection.
How a FIP x FIP Coupling Works
A FIP x FIP coupling joins two compatible male-threaded piping components along the same straight piping path.
An appropriate thread-sealing method should be applied to the mating male pipe threads before assembly. Each component is then threaded into one end of the coupling.
Once properly assembled, the coupling creates a compact inline connection without introducing an elbow, branch, or other change in piping direction.

FIP x FIP Coupling Design
Female-to-Female Threaded Connection
Female pipe-thread connections on both ends allow two compatible male-threaded piping components to be joined through one compact fitting.
Straight-Through Configuration
Unlike an elbow or tee, the coupling maintains the direction of the piping run and provides a direct inline connection between components.

Lead-Free Brass Benefits
Lead-free brass combines the durability and corrosion resistance associated with brass fittings with material construction intended for applications requiring lead-free plumbing components.
Brass threaded couplings provide durable, serviceable connections and are commonly used for joining compatible threaded components in water, plumbing, agricultural, and industrial piping arrangements.
Installation & Selection Considerations
- Confirm both mating components use compatible male pipe threads before ordering.
- Use a thread-sealing method suitable for brass fittings and the intended media.
- Avoid excessive tightening that could damage the coupling or mating threaded components.
- Support connected piping to reduce unnecessary mechanical stress on the fitting.
- Verify pressure, temperature, media, and lead-free application requirements before installation.

Frequently Asked Questions
What is a Lead-Free Brass FIP x FIP Coupling?
It is a straight brass fitting with female pipe-thread connections on both ends for joining two compatible male-threaded piping components.
What does FIP x FIP mean?
FIP refers to female pipe thread. FIP x FIP means the coupling has female pipe-thread connections on both ends.
What connects to this coupling?
Compatible male-threaded pipe, nipples, valves, adapters, and other piping components can connect to the two female-threaded ends.
Does this coupling change the direction of the piping?
No. A coupling provides a straight-through inline connection and does not create an elbow or branch in the piping run.
What material is this coupling made from?
This coupling features lead-free brass construction.
What is a brass coupling commonly used for?
A coupling is commonly used to join compatible threaded components along a straight piping run, extend piping, or connect pipe to another threaded component.
Should thread sealant be used with this coupling?
Use a thread-sealing method appropriate for brass pipe-thread connections, the transferred media, and the intended application.
