Description
125# Flanged Concentric Reducer
125# Flanged Concentric Reducers are designed to transition between two different nominal pipe sizes while maintaining a centered flow path in compatible flanged piping systems.
Manufactured from grey iron castings conforming to ASTM A126 and ASTM A48, these reducers provide a durable size transition for waterworks, wastewater, HVAC, fire protection, municipal, commercial, and industrial piping applications. Flanged fitting dimensions conform to ASME B16.1 and ANSI/AWWA C110/A21.10, and Class 125 fittings are UL Listed through 12".

Concentric Reducer Configuration
Larger Flanged End
The larger flanged connection bolts to a compatible mating flange on the larger nominal pipe size.
Centered Reduction
The reducer body transitions symmetrically around the centerline to maintain a centered piping path.
Smaller Flanged End
The reduced flanged connection connects to the smaller adjoining pipe or compatible flanged component.
Construction Details
These 125# flanged concentric reducers are manufactured from grey iron castings conforming to ASTM A126 and ASTM A48.
Flanged fitting dimensions conform to ASME B16.1 and ANSI/AWWA C110/A21.10. The concentric design provides a symmetrical transition between pipe sizes while keeping both connection centerlines aligned.
Why Choose a 125# Flanged Concentric Reducer?
Centered Pipe Size Transition
- Connects two different nominal pipe sizes
- Maintains a common centerline
- Flanged connections on both ends
- Provides a smooth, symmetrical reduction
- Suitable for compatible Class 125 systems
Grey Iron Construction
- Grey iron castings
- Conforms to ASTM A126 and ASTM A48
- Dimensions conform to ASME B16.1
- Also references ANSI/AWWA C110/A21.10
- Manufactured in an ISO-certified facility
Concentric Reducer vs. Eccentric Reducer
Concentric Reducer
A concentric reducer transitions symmetrically around the piping centerline, keeping the larger and smaller connections centered with one another.
Eccentric Reducer
An eccentric reducer uses an offset transition rather than a centered one and is selected when maintaining one side of the piping elevation is required.

Frequently Asked Questions
What is a 125# flanged concentric reducer?
It is a grey iron flanged fitting designed to connect two different nominal pipe sizes while keeping both connections aligned on the same centerline.
What does concentric mean?
Concentric means the reduction is symmetrical around the centerline of the fitting, keeping the larger and smaller openings centered with one another.
What type of connections does this reducer use?
The fitting uses flanged connections on both ends.
How is a concentric reducer different from an eccentric reducer?
A concentric reducer keeps both pipe sizes on the same centerline, while an eccentric reducer offsets the transition to maintain one side of the piping elevation.
What material is this reducer made from?
The supplied product information states that the fitting uses grey iron castings conforming to ASTM A126 and ASTM A48.
What dimensional standards apply?
Flanged fitting dimensions conform to ASME B16.1 and ANSI/AWWA C110/A21.10.
Is this fitting UL Listed?
The supplied product information states that Class 125 fittings are UL Listed through 12".
Can this reducer be installed vertically?
The centered configuration can be used in compatible horizontal or vertical piping layouts when permitted by the system design and applicable specifications.
Is the manufacturing facility ISO certified?
Yes. The supplied product information states that the manufacturing facility is ISO certified.
What should I verify before ordering?
Confirm both nominal pipe sizes, flange dimensions, bolt patterns, gasket requirements, Class 125 requirements, material compatibility, and applicable piping-system specifications before ordering.
