Description
150# Black Malleable Iron Reducing 90° Elbow
150# Black Malleable Iron Reducing 90° Elbows are designed to change piping direction by 90 degrees while simultaneously transitioning between two different nominal pipe sizes. This combination fitting can help simplify threaded piping layouts by reducing the need for a separate reducer and standard elbow.
Manufactured from durable malleable iron, these Class 150 fittings provide dependable threaded connections for industrial, commercial, and mechanical piping systems including water, gas, oil, and fire protection applications.

Construction & Applications
Malleable Iron Construction
Manufactured from malleable iron castings conforming to ASTM A197 for dependable strength and durability in threaded piping applications.
Reducing Design
The two openings are different nominal pipe sizes, allowing the fitting to transition between pipe diameters while maintaining a threaded connection.
90° Direction Change
The fitting creates a right-angle turn while reducing pipe size, helping simplify compact piping layouts and reduce the number of individual fittings required.
Why Use a Reducing 90° Elbow?
Two Functions in One Fitting
A reducing elbow combines a 90-degree directional change with a pipe-size transition, potentially replacing a separate reducing fitting and standard elbow.
Compact Piping Layouts
Combining the size transition and directional change can help shorten threaded assemblies and reduce the number of joints in confined piping installations.
Typical Applications
Industrial & Mechanical Piping
- Industrial piping systems
- Mechanical piping
- Commercial installations
- Threaded reducing connections
Common Services
- Water piping
- Gas piping

Frequently Asked Questions
What is a reducing 90° elbow?
A reducing 90° elbow changes piping direction by 90 degrees while connecting two different nominal pipe sizes.
Why use a reducing elbow instead of a standard elbow?
A reducing elbow combines a size transition and directional change in one fitting, which can reduce the number of separate components required in the piping assembly.
Are both ends the same size?
No. A reducing elbow has different nominal connection sizes on its two openings.
What material is this fitting made from?
The fitting is manufactured from malleable iron castings conforming to ASTM A197.
What type of threads does the fitting use?
The fitting uses NPT threads conforming to ASME B1.20.1.
What dimensional standard applies?
Malleable fitting dimensions conform to ASME B16.3.
Is this a Class 150 fitting?
Yes. This is a 150# black malleable iron reducing elbow.
Is this fitting UL Listed and FM Approved?
Yes. The supplied product information states that Class 150 fittings are UL Listed and FM Approved at 300 PSI.
Where are these fittings manufactured?
The listed countries of origin are Thailand and China, and the manufacturing facility is ISO certified.
What dimensions should I confirm before ordering?
Verify both nominal connection sizes because this is a reducing fitting. The pipe size chart in the Ask Willy section can help confirm sizing before ordering.
Important Ordering & Installation Notes
- Confirm both nominal connection sizes before ordering.
- This fitting combines a pipe-size reduction with a 90° directional change.
- Connections are female NPT threaded and conform to ASME B1.20.1.
- Confirm which connection size is required on each side of the installation.
- Use compatible pipe, fittings, thread sealant, and installation practices for the intended piping system.
- Verify system pressure, service, code, and approval requirements before installation.
- Refer to the Service Metal specification sheet and Certificate of Conformance for additional product information.
