A reducer socket fitting is typically used in pump station pipe work to reduce the size of the suction pipe to match the size of the pump suction end flange. Reducer fittings used in pump inlet pipe work are divided into two types—concentric and eccentric reducers.
The two types of reducer socket fittings can be described as:
- Concentric reducer—The reduction of the pipe size is achieved by decreasing the diameter of the fitting at a constant rate over a specified length, maintaining symmetry around the fitting.
- Eccentric reducer—The reduction of the pipe size is achieved by decreasing the diameter of the fitting at a constant rate over a specified length, maintaining one side of the fitting horizontally.




Outstanding product — robust, smooth, and accurate in every aspect. The CS seamless reducer sockets aligned perfectly with our Schedule 40 carbon steel pipes. Zero leakage even under high pressure. Excellent job by the manufacturer.
Good quality and accurate sizing. The reducer sockets were seamless, well-finished, and free from any surface defects. Installation went smoothly without any misalignment. Would recommend for industrial and mechanical applications.
We procured several CS Reducer Sockets for our boiler line modification. The weldability and surface finish were excellent. The Schedule 40 wall thickness gives the right balance of strength and durability. Passed all hydro tests easily.
The product quality is very consistent. The seamless CS Reducer Socket had clean internal finishing and proper dimensions. Works well for both low and high-pressure pipelines. Just a slight delay in dispatch, but overall, very satisfied with the purchase.
Excellent quality reducer sockets! The CS seamless construction is strong and precisely machined. We used these in our condensate line — perfect fit and leak-free joints after welding. Schedule 40 thickness makes it ideal for pressure applications.
