Reducers for Food, Dairy, and Beverage

CSI's extensive stock of sanitary fittings—including Alfa Laval reducers—helps us ship you the fittings you need, when you need them. Alfa Laval reducers have cylindrical welding ends and are available for all tube combinations, meaning you will always get the right diameter and wall thickness for your process.

Alfa Laval's 304 and 316L reducers are compliant with the 3-A sanitary standard; all surfaces are polished to 32 microinch Ra or better. Alfa Laval continues to lead the industry with fittings that are produced to the high standards you’ve come to expect.

For reducers that meet BPE specifications, check out ourBPE Reducers. CSI also offersAL-6XN® Alloy ReducersandHastelloy® C-22® Reducersfor more corrosion resistance and, for reduction with the shortest overall length, see our31WMP Reducing Ferrules.

These fittings are 3-A approved.
