Gaskets for All Industries

Hygienic seals are used widely in virtually all sanitary applications to seal clamp connections in sanitary pipe lines.

Central States Industrial (CSI) stocks a wide variety of sanitary gaskets from Rubber Fab and Newman Gasket Company. We offer standard and specialty gaskets in several elastomers and fluoroelastomers. Our sanitary gaskets are compliant with FDA, USDA, and 3-A criteria. USP Class VI compliant gaskets are also available.

For more information about gaskets and how to choose the right one for your application, contact CSI today.
