FFKM Gaskets 

Kalrez® Perfluoroelastomer (FFKM)

We are a manufacturer of FFKM gaskets and seals. When all else fails, Kalrez® Perfluoroelastomer is up to the challenge where you need the chemical resistance of TeflonTM and the rubber sealing character of an elastomer. Kalrez® is preferred in the natural flavoring industry where the widest number of complex natural molecules exist and where flavor or aroma cannot be imparted to the product. Kalrez® is also used in the harshest areas of bioprocessing and food processing where broad chemical resistance, steaming and vacuum processes are combined. Newman Sanitary Gasket company can provide gaskets, O-rings and custom molded parts made from  various Kalrez® FDA and USP compliant compounds.

Kalrez® 6221 (White) and Kalrez®6230 (Black) O-rings

For FDA and USP food, dairy and biopharmaceutical processing, Kalrez® 6221 (White) and Kalrez®6230 (Black) O-rings are made to provide long-lasting high purity seals in pumps, agitators, sensors, or wherever an O-ring is used.

Kalrez® LS-390  (Grey)

Kalrez® LS-390 (Life Sciences) has limited availability and will be phased out.
