Tube Reducers / Transitions - 316L Stainless
PNW Sanitary Butt-Weld Concentric Reducers provide a hygienic, permanent solution for transitioning between different sanitary tubing sizes while maintaining a centered flow path. Designed for welded process systems, concentric reducers help promote smooth product flow, minimize turbulence, and support efficient cleaning in sanitary applications.
Manufactured from 316L stainless steel and polished to a 32Ra sanitary finish, these reducers are 3-A Certified and engineered for demanding food, beverage, dairy, brewery, cosmetic, nutraceutical, and pharmaceutical environments. The low-carbon 316L alloy offers enhanced corrosion resistance and is well suited for applications involving aggressive cleaning chemicals, high-purity media, and frequent CIP procedures.
Available in a wide range of size combinations, PNW Sanitary 31W Butt-Weld Concentric Reducers are designed for orbital or manual welding and provide a durable, crevice-free connection for long-term sanitary performance.
