Eccentric reducers connect pipes of varying diameters while offsetting the centerline. This design prevents the formation of air pockets or stagnant fluid zones in horizontal pipe runs. They are essential in systems where maintaining a consistent bottom-of-pipe level is critical, such as in drainage or chemical processing pipelines.
