Eccentric Reducers

Stainless Steel Gaskets

The eccentric reducer is a key component in piping systems designed to smoothly transition between pipes of different diameters while maintaining a consistent flow path. Unlike concentric reducers, eccentric reducers have an offset centerline that aligns with the bottom of the pipe, which helps in managing fluid flow and preventing air pockets or sediment accumulation. This fitting is commonly used in industries such as oil and gas, chemical processing, and water treatment, where maintaining a level flow line is crucial.


Constructed from high-quality materials, eccentric reducers are built to endure high pressures and varying temperatures, ensuring robust performance in demanding applications. The eccentric design helps to minimize pressure drops and turbulence, enhancing overall flow efficiency. Adhering to strict industry standards, including ASTM, ASME, and ANSI, these reducers are engineered for reliability and longevity. Their precision manufacturing and durable construction make them an excellent choice for applications requiring smooth transitions and effective flow management.
