Description
Lead-Free Brass Reducing Street Elbow FIP x MIP 90°
Lead-Free Brass Reducing Street Elbows provide a 90-degree threaded transition between a female pipe-thread connection and a male pipe-thread connection of different nominal sizes. The reducing street-elbow configuration combines a directional change and a size transition in one compact fitting.
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 formed in a 90-degree street-elbow configuration.
One end provides an internal female pipe-thread connection, while the opposite end provides an external male pipe-thread connection. The two ends are different nominal sizes to provide the reducing transition.
This design combines a 90° change in piping direction with a threaded size reduction, helping minimize the number of separate fittings required in compact piping layouts.
Connection Configuration
Female Pipe Thread - FIP
The female pipe-thread connection accepts a compatible male-threaded pipe, nipple, valve, adapter, or other piping component.
Male Pipe Thread - MIP
The male pipe-thread connection installs into a compatible female-threaded fitting, coupling, valve, manifold, or equipment connection.
How a Reducing Street Elbow Works
A FIP x MIP reducing street elbow connects compatible threaded components while changing the piping direction by 90 degrees and transitioning between two different nominal pipe sizes.
The male MIP end threads into a compatible female-threaded connection, while the female FIP end accepts the mating male-threaded component.
An appropriate thread-sealing method should be applied to applicable male pipe threads according to the fitting material, transferred media, and requirements of the piping system.

Reducing Street Elbow Design
Female-to-Male Transition
The fitting combines a female threaded connection and a male threaded connection, allowing compatible piping components with opposite thread configurations to be joined directly.
90° Reducing Configuration
The street-elbow body changes the piping direction by 90 degrees while the different connection sizes provide the required reduction.
Reducing Street Elbow vs. Standard Street Elbow
Reducing Street Elbow
FIP x MIP - Different Sizes
Provides a 90-degree change in direction while transitioning between two different compatible threaded pipe sizes.
Standard Street Elbow
FIP x MIP - Same Size
Provides a 90-degree female-to-male threaded transition while typically maintaining the same nominal pipe size through the fitting.

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 reducing street-elbow configuration combines a 90-degree change in direction with a threaded size transition, helping simplify piping layouts where both functions are required.
Installation & Selection Considerations
- Confirm both the FIP and MIP connection sizes before ordering.
- Verify the required 90° orientation and reducing configuration.
- Use a thread-sealing method suitable for brass fittings and the intended media.
- Avoid excessive tightening that could damage the fitting or mating threads.
- Verify pressure, temperature, media, and lead-free application requirements before installation.

Frequently Asked Questions
What is a Lead-Free Brass Reducing Street Elbow?
It is a 90-degree threaded fitting with a female pipe-thread connection on one end and a male pipe-thread connection on the other, with different nominal sizes for reducing service.
What does FIP x MIP mean?
FIP refers to the female pipe-thread connection, while MIP refers to the male pipe-thread connection.
Why is this called a reducing street elbow?
It combines a female-to-male street-elbow configuration with two different nominal pipe sizes, providing both a 90-degree turn and a size reduction.
What angle does this fitting provide?
The fitting changes the piping direction by 90 degrees.
What connects to the FIP side?
The female pipe-thread connection accepts a compatible male-threaded pipe, nipple, valve, adapter, or other component.
What connects to the MIP side?
The male pipe-thread connection installs into a compatible female-threaded fitting, valve, coupling, manifold, or equipment port.
What material is this fitting made from?
This reducing street elbow 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.
