Description
150# Black Malleable Iron Reducing 90° Elbow
150# black malleable iron reducing 90-degree elbows are designed to change the direction of threaded piping by 90 degrees while reducing from a larger nominal pipe size to a smaller size. Female NPT threads on both ends allow the fitting to connect compatible male-threaded pipe, pipe nipples, or fittings while combining a directional change and pipe-size reduction in one compact fitting.
Select the required reducing size combination from the product options above. The selected variation determines the manufacturer item number, selling price, weight, and other size-specific product information.

How a Reducing 90° Elbow Works
A reducing 90-degree elbow has two female NPT threaded openings of different nominal pipe sizes. The larger opening connects to the larger male-threaded pipe or fitting, while the smaller opening connects to the reduced pipe size. This allows the piping system to turn 90 degrees and reduce line size within one fitting, eliminating the need to install a separate standard elbow and reducer.

Frequently Asked Questions
What is a reducing 90-degree elbow used for?
A reducing 90-degree elbow is used to change the direction of threaded piping by 90 degrees while transitioning from a larger nominal pipe size to a smaller nominal pipe size.
How is a reducing 90-degree elbow different from a standard 90-degree elbow?
A standard 90-degree elbow has equal-size threaded connections on both ends. A reducing 90-degree elbow has two different connection sizes, allowing it to turn the piping while reducing the line size.
Are both ends female NPT threaded?
Yes. Both connections are female NPT threads. The larger opening accepts the larger male-threaded pipe or fitting, and the smaller opening accepts the reduced pipe size.
Which size is listed first in the product variation?
The larger nominal pipe size is listed first, followed by the smaller reduced connection size. For example, a 1" x 3/4" reducing elbow has a 1-inch female NPT connection and a 3/4-inch female NPT connection.
Can this fitting replace a standard elbow and separate reducer?
Yes. A reducing 90-degree elbow combines the directional change and pipe-size reduction into one fitting, which can reduce installation space and the number of threaded joints required.
What pressure class is this fitting?
This black malleable iron reducing 90-degree elbow is manufactured as a 150# or Class 150 threaded fitting.
What sizes are available?
Available product variations range from 3/8" x 1/8" through 4" x 3". Select the required reducing size combination from the product options above.
Can this elbow be used with black steel pipe nipples?
Yes. It is designed to connect compatible male NPT-threaded black steel pipe, pipe nipples, and other approved threaded components in the selected nominal pipe sizes.
Can this elbow be used for gas, water, oil, air, or steam?
It may be used in compatible gas, water, oil, compressed-air, steam, and general-service systems when the application remains within the pressure, temperature, media, code, and manufacturer specification requirements.
Should thread sealant be used during installation?
An approved pipe-thread sealant or thread tape should be selected based on the piping media, pressure, temperature, applicable codes, and manufacturer recommendations.
Important Ordering Notes
- Select the required reducing size combination before adding the product to your cart.
- The larger nominal pipe size is listed first, and the smaller reduced connection is listed second.
- This fitting has female NPT threaded connections on both ends.
- Confirm that a 90-degree directional change and the selected pipe-size reduction are appropriate for the piping layout.
- The selected variation determines the Charman item number, price, weight, and carton quantity.
- Confirm the thread type and nominal pipe size of both mating components before ordering.
- Confirm pressure, temperature, media compatibility, and application requirements before installation.
- Use an approved thread sealant suitable for the piping media and operating conditions.
- Support connected piping properly to avoid placing excessive mechanical stress on the fitting.
- Installation should be completed by qualified personnel and comply with applicable codes and standards.
- Manufacturer warranty coverage is subject to the terms, limitations, and exclusions in the linked warranty document.
