Stainless & Carbon Steel Concentric & Eccentric Reducers
Concentric reducers maintain a centered axis for vertical piping transitions, ideal for smooth flow in pump inlets and vertical risers. Eccentric reducers keep one side flat, preventing air pockets in horizontal liquid lines and sediment buildup in gas or slurry systems.
