Applications & Selection Guide

Stainless steel concentric reducers in AISI 304 to EN 10253 / ASME B16.9, joining two tube diameters on a shared centreline with plain ends for welding. The symmetric cone maintains even flow distribution through the transition.

Use concentric reducers on vertical stainless lines and pump discharge sides in food, beverage, water treatment, and chemical installations. On horizontal suction lines choose the eccentric version to avoid air entrapment. Large × small OD combinations are listed in the table above; 316L can be offered for chloride service on request.

Quoted and sold per piece. Send both ODs, quantity, and destination in a quote request for exact pricing.
