Description
304 Stainless Steel Butt Weld Concentric Reducer - Sch 40
304/L Stainless Steel Schedule 40S Butt Weld Concentric Reducers provide a smooth, centered transition between different pipe sizes. Manufactured from ASTM A/SA403 WP304/L stainless steel, these fittings offer dependable corrosion resistance, strength, and weldability for commercial, industrial, and process piping systems.
The concentric design keeps the inlet and outlet pipe centerlines aligned, supporting a balanced flow transition while helping reduce turbulence and pressure loss. Available reducing combinations range from 3/4" × 1/2" through 10" × 8".

Construction Details
304/L Stainless Steel
Manufactured from dual-certified WP304/L stainless steel, combining the corrosion resistance of Type 304 with the lower carbon content and improved weldability of Type 304L.
Concentric Taper
The symmetrical tapered body maintains a common centerline between the larger and smaller pipe ends for a balanced reduction in pipe diameter.
Schedule 40S Fit-Up
Each reducer is formed to ASME B16.9 dimensions for accurate fit-up with corresponding Schedule 40S stainless steel pipe.

Why Use a Concentric Reducer?
A concentric reducer transitions between different pipe diameters while keeping both pipe centerlines aligned. The symmetrical taper supports a smooth, balanced reduction and is commonly used where maintaining a common piping centerline is important.
Schedule 40S Construction
Schedule 40S stainless steel reducers use a heavier wall than comparable Schedule 10S fittings. This provides additional mechanical strength while maintaining compatibility with corresponding Schedule 40S stainless steel piping.
Available Size Combinations
These Schedule 40S stainless steel concentric reducers are available in multiple reducing combinations ranging from 3/4" × 1/2" through 10" × 8". Select the larger and smaller nominal pipe sizes required for the piping system being connected.

Frequently Asked Questions
What is a concentric reducer used for?
A concentric reducer connects two different pipe diameters while keeping the larger and smaller pipe ends aligned on a common centerline.
What material are these reducers made from?
These reducers are manufactured from ASTM A/SA403 WP304/L stainless steel.
What pipe schedule are these reducers designed for?
These concentric reducers are designed for Schedule 40S stainless steel piping systems.
What is the difference between a concentric and eccentric reducer?
A concentric reducer keeps the inlet and outlet centered on a common centerline. An eccentric reducer offsets the transition so one side of the piping run remains aligned.
What connection type is used?
These fittings use butt weld connections to create permanent welded joints with compatible Schedule 40S stainless steel piping.
What dimensional standard do these reducers meet?
The reducers are manufactured to ASME B16.9 dimensional requirements.
What reducing sizes are available?
Available reducing combinations range from 3/4" × 1/2" through 10" × 8".
How do I select the correct reducer size?
Select the fitting according to both the larger and smaller nominal pipe sizes required in the system, and confirm that the corresponding Schedule 40S wall thicknesses are compatible.
Important Ordering & Installation Notes
