General product information
11443001 FFKM O-ring KALREZ® 6230 O-rings are engineered for ultra-demanding environments, providing reliable sealing performance in both static and dynamic applications. These FFKM seals ensure durability, chemical resistance, and long service life even under demanding operating conditions. They are widely used in industries such as semiconductor manufacturing, chemical processing, oil and gas, automotive, food and beverage, and pharmaceutical production, where consistent sealing performance is critical. Thanks to their material properties, these O-rings perform well in harsh environments, reducing maintenance needs and improving operational safety compared to standard elastomers. It's a material which is compliant with the United States’ Food and Drug Administration’s regulations for repeated use in contact with food as described by 21 CFR177.2600 and Food Contact Notification 000101. Kalrez® parts made from compound 6230 have been tested in accordance with the United States Pharmacopoeia Class VI (USP Class VI) testing protocol and meet the test requirements of a USP Class VI polymer. This is a black product that offers excellent steam cycling resistance and reduces extractables from sealing materials to trace levels. The maximal service temperature for Kalrez® 6230 is up to 260°C.
