Description
150# Black Malleable Iron 90° Elbow
150# black malleable iron 90° elbows are designed to create a 90-degree change in direction between two male-threaded pipe ends, pipe nipples, or compatible fittings of the same nominal size. Female NPT connections on both openings make these elbows suitable for commercial plumbing, industrial piping, compressed-air, natural-gas, water, oil, fire-protection, and approved steam applications.
Select the required nominal pipe size from the product options above. The selected variation determines the Charman item number, selling price, weight, cost, and other size-specific product information.

Frequently Asked Questions
What is a black malleable iron 90° elbow used for?
A black malleable iron 90° elbow connects two male-threaded pipe ends while changing the direction of the piping system by 90 degrees.
Does this elbow have female threads on both openings?
Yes. Both openings have female NPT threads for connection to compatible male-threaded pipe, pipe nipples, or fittings.
Are both openings the same nominal pipe size?
Yes. This is a standard equal-size elbow. Select a reducing 90° elbow when different inlet and outlet sizes are required.
What is the difference between a standard elbow and a reducing elbow?
A standard elbow has two equal-size connections. A reducing elbow changes direction while also connecting two different nominal pipe sizes.
What pressure class is this fitting?
This black malleable iron elbow is manufactured as a 150# or Class 150 threaded fitting.
What sizes are available?
Available product variations range from 1/8" through 6" nominal pipe size. Select the required size 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.
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 applicable pressure, temperature, media, code, and manufacturer 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.
