Description
150# Black Malleable Iron 45° Elbow
150# black malleable iron 45-degree elbows are designed to change the direction of threaded piping by 45 degrees while maintaining a secure, compact connection. Female NPT threads on both ends connect compatible male-threaded pipe, pipe nipples, or fittings of the same nominal size for use in 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 manufacturer item number, selling price, weight, carton quantity, and other size-specific product information.

How a 45° Pipe Elbow Works
A threaded 45-degree elbow has two female NPT connections positioned at a 45-degree angle. Male-threaded pipe, pipe nipples, or compatible fittings are threaded into each opening, allowing the piping system to change direction gradually without creating a sharp 90-degree turn. Both connections on this standard elbow are the same nominal pipe size.

Frequently Asked Questions
What is a black malleable iron 45-degree elbow used for?
A black malleable iron 45-degree elbow is used to change the direction of threaded piping by 45 degrees while maintaining an equal-size connection between two male-threaded pipe ends.
Does this elbow have female threads on both ends?
Yes. This standard 45-degree elbow has female NPT threads on both ends for connecting compatible male-threaded pipe, pipe nipples, or fittings.
Are both connections the same nominal pipe size?
Yes. This is an equal-size elbow, meaning both female NPT connections are the same nominal pipe size.
What is the difference between a 45-degree elbow and a 90-degree elbow?
A 45-degree elbow changes piping direction by 45 degrees and creates a more gradual turn. A 90-degree elbow changes piping direction by 90 degrees and creates a sharper turn.
Can this elbow connect two different pipe sizes?
No. This standard elbow has equal-size connections. A reducing elbow or additional reducing fittings are required when connecting different nominal pipe sizes.
What pressure class is this fitting?
This black malleable iron 45-degree 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 of the same nominal size.
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 nominal pipe size before adding the product to your cart.
- This is an equal-size 45-degree elbow with female NPT connections on both ends.
- Confirm that a 45-degree directional change is appropriate for the piping layout.
- The selected variation determines the Charman item number, price, weight, and carton quantity.
- Confirm the thread type and nominal 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.
