Markez O-rings

Perfluoroelastomer FFKM O-Ring materials provide the highest temperature (up to 620°F) and most universal chemical resistance of any rubber O-Ring and Gasket material. Perfluoroelastomer O-Ring high temperature and chemical performance comes at a high price so only utilized in the most demanding cost benefit applications. FFKM O-Rings are available in a variety of brand names like Kalrez®, Chemraz®, Simriz® and Markez®. Perfluoroelastomer O-Rings are also available in many specific compound formulations engineered for targeted application performance like low or high temperature and chemical compatibility. Please refer to our FFKM O-Ring material comparison chart to compare relative price and performance properties some of the more popular perfluoroelastomer brands and compounds.
