Carbon Steel eccentric reducers are pipe fittings designed to connect two pipes of different diameters, with the smaller outlet off-center to the large inlet. This off-center alignment allows for the maintenance of the same top or bottom pipe level, which helps in preventing the buildup of air or fluid in the piping system.

Carbon Steel concentric reducers have aligned centerlines, making them suitable for vertical piping systems where centered flow is needed. Carbon steel eccentric reducers have an offset centerline, preventing air pockets. Concentric reducers are ideal for pumps and compressors, while eccentric reducers are used in suction lines to avoid cavitation.
