Construction & Applications
Malleable Iron Construction
Manufactured from malleable iron castings conforming to ASTM A197 for dependable strength and durability in demanding threaded piping systems.
Class 300 Design
The heavier Class 300 construction is intended for more demanding piping applications than standard Class 150 malleable iron fittings.
90° Directional Change
The elbow creates a right-angle turn in the piping system while maintaining threaded connections at both ends.
Why Use a 300# Malleable Iron Elbow?
Higher-Duty Piping Applications
Class 300 fittings are commonly selected where a more robust threaded fitting is required for demanding industrial, mechanical, gas, air, oil, or fluid piping service.
Compact 90-Degree Turn
A threaded 90-degree elbow provides a simple way to route piping around equipment, structural obstacles, or changes in system layout without additional fittings.
Typical Applications
Industrial & Mechanical Piping
- Industrial piping systems
- Mechanical piping
- Compressed air systems
- General fluid piping
- Equipment connections
Common Service Applications
- Gas piping
- Oil piping
- Air lines
- Utility piping
- Higher-duty threaded systems

Frequently Asked Questions
What is a 300# black malleable iron 90-degree elbow used for?
It is used to create a 90-degree directional change in a higher-duty threaded piping system.
What type of connections does this elbow use?
The elbow uses female NPT threaded connections on both ends.
How is a 300# elbow different from a 150# elbow?
The Class 300 elbow is a heavier-duty fitting intended for more demanding threaded piping applications than a standard Class 150 fitting.
What materials are these fittings made from?
The supplied product information states that the malleable iron castings conform to ASTM A197.
What dimensional standard applies?
Malleable fitting dimensions conform to ASME B16.3.
What thread standard applies?
NPT threads conform to ASME B1.20.1.
Are Class 300 malleable iron fittings UL Listed?
Yes. The supplied product information states that Class 300 fittings are UL Listed.
What piping applications are these elbows commonly used in?
They are commonly used in industrial, commercial, mechanical, gas, air, oil, and compatible fluid piping systems.
Does this elbow reduce pipe size?
No. This is a standard 90-degree elbow intended to connect matching nominal pipe sizes. Use a reducing fitting when a change in pipe size is required.
What should I verify before ordering?
Confirm the nominal pipe size, connection type, required fitting class, service conditions, and applicable system requirements before ordering.
Important Ordering & Installation Notes
- Confirm the required nominal pipe size before ordering.
- This fitting uses female NPT threaded connections on both ends.
- The elbow provides a 90° directional change without reducing pipe size.
- Confirm that Class 300 construction is appropriate for the intended piping system.
- NPT threads conform to ASME B1.20.1.
- Malleable fitting dimensions conform to ASME B16.3.
- Use compatible pipe, fittings, thread sealant, and accepted threaded installation practices.
- Do not assume the “300#” class designation alone establishes the allowable working pressure for every service condition.
- Verify pressure, temperature, media compatibility, applicable codes, and system requirements before installation.
- Refer to the specification sheet and Certificate of Conformance for additional product information.
