Construction & Applications
Malleable Iron Construction
Manufactured from malleable iron castings conforming to ASTM A197 for dependable strength and durability in threaded piping systems.
Reducing Configuration
The two threaded openings are different nominal sizes, allowing the fitting to reduce the pipe size while simultaneously changing direction.
Hot-Dip Galvanized Finish
The galvanized coating conforms to ASTM A153 and provides additional protection against rust and corrosion in moisture-prone and outdoor installations.
Why Use a Reducing 90 Elbow?
Two Functions in One Fitting
A reducing elbow combines the directional change of a standard 90-degree elbow with the size transition of a reducing fitting, helping reduce the total number of components in the piping system.
Compact Piping Layout
Combining the reduction and directional change can shorten the overall assembly and is especially useful where available installation space is limited.
Typical Applications
Commercial & Mechanical Piping
- Commercial plumbing systems
- Mechanical piping
- Water distribution
- General utility piping
- Space-limited piping layouts
Galvanized Applications
- Outdoor piping
- Moist environments
- Water-service applications
- Industrial installations
- General galvanized piping systems

Frequently Asked Questions
What is a reducing 90 degree elbow?
A reducing 90-degree elbow changes piping direction by 90 degrees while connecting two different nominal pipe sizes.
How is a reducing elbow different from a standard elbow?
A standard elbow typically connects the same nominal pipe size at both ends, while a reducing elbow has two different connection sizes.
Can a reducing elbow replace a separate elbow and reducer?
In many piping layouts, yes. The fitting combines the directional change and pipe-size reduction into one component.
What type of connections does this fitting use?
The fitting uses female NPT threaded connections in two different nominal sizes.
Why choose a galvanized reducing elbow?
The hot-dip galvanized finish provides additional protection against rust and corrosion in installations exposed to moisture or outdoor conditions.
What standard applies to the galvanized coating?
The supplied product information states that hot-dipped galvanized fittings conform to ASTM A153.
What thread standard applies?
NPT threads conform to ASME B1.20.1.
Is this fitting UL Listed and FM Approved?
Yes. The supplied product information states that Class 150 fittings are UL Listed and FM Approved at 300 PSI.
Does the supplied information include lead-compliance requirements?
Yes. It states that galvanized fittings meet ANSI/NSF 61-4 Annex G and CA AB1953 with less than 0.25% lead.
What sizes should I verify before ordering?
Verify both nominal connection sizes and confirm which side of the elbow must connect to the larger and smaller pipe before ordering.
Important Ordering & Installation Notes
- Confirm both nominal connection sizes before ordering.
- Verify the required orientation of the larger and smaller connection in the piping layout.
- This fitting provides a 90° directional change while reducing pipe size.
- The fitting uses female NPT threaded connections.
- NPT threads conform to ASME B1.20.1.
- Hot-dipped galvanized fittings conform to ASTM A153 according to the supplied product information.
- Use compatible galvanized pipe, fittings, thread sealant, and accepted threaded installation practices.
- Avoid damaging the galvanized coating during handling and installation.
- Verify system pressure, service, potable-water, code, and approval requirements before installation.
