Construction & Applications
Malleable Iron Construction
Manufactured from malleable iron castings conforming to ASTM A197 for dependable strength and durability in demanding threaded piping systems.
90° Directional Change
The elbow creates a compact right-angle turn in a threaded piping run and is useful where piping must be routed around equipment, walls, or structural components.
Hot-Dip Galvanized Finish
The galvanized coating conforms to ASTM A153 and provides added protection against rust and corrosion in moisture-prone and outdoor environments.
Why Choose a 300# Galvanized Elbow?
Higher-Duty Construction
Class 300 malleable iron fittings are intended for more demanding threaded piping applications than standard Class 150 fittings.
Added Corrosion Resistance
The hot-dip galvanized coating helps protect the fitting in environments exposed to moisture, humidity, weather, and other conditions where bare black iron may be less suitable.
Typical Applications
Mechanical & Commercial Piping
- Mechanical piping systems
- Commercial plumbing
- HVAC piping
- Water distribution
- Compressed air systems
- General utility piping
Galvanized & Outdoor Applications
- Outdoor piping
- Moist environments
- Waterworks installations
- Industrial piping
- General galvanized piping systems

Frequently Asked Questions
What is a 300# galvanized malleable iron 90-degree elbow used for?
It is used to create a 90-degree directional change in a higher-duty threaded piping system while providing added corrosion resistance from the galvanized finish.
What type of connections does this elbow use?
The elbow uses female NPT threaded connections on both ends.
Why choose galvanized instead of black malleable iron?
The hot-dip galvanized coating provides added protection against rust and corrosion in piping exposed to moisture, humidity, or outdoor conditions.
How is a 300# elbow different from a 150# elbow?
The Class 300 fitting is a heavier-duty fitting intended for more demanding threaded piping applications than a standard Class 150 fitting.
What material standard applies?
The supplied product information states that the malleable iron castings conform to ASTM A197.
What standard applies to the galvanized coating?

Are Class 300 fittings UL Listed?
Yes. The supplied product information states that Class 300 fittings are UL Listed.
What should I verify before ordering?
Confirm nominal pipe size, female NPT connections, required fitting class, service conditions, and applicable piping-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 creates 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.
- Hot-dipped galvanized fittings conform to ASTM A153.
- Use compatible galvanized pipe, fittings, and thread sealant appropriate for the intended system.
- Avoid damaging the galvanized coating during handling and installation.
- Do not assume the “300#” class designation alone establishes allowable working pressure for every service condition.
- Verify pressure, temperature, media compatibility, potable-water requirements, applicable codes, and approval requirements before installation.
- Refer to the specification sheet and Certificate of Conformance for additional product information.
