Simriz FFKM O-Rings

Simriz® FFKM (perfluoroelastomer) O-rings are high-performance sealing solutions designed for extreme chemical, thermal, and plasma environments. Manufactured by Freudenberg and Simrit, Simriz® FFKM O-rings, gaskets, custom molded parts, and tubes are widely used in semiconductor, chemical processing, oil & gas, and pharmaceutical applications where maximum reliability and resistance to aggressive media are required.


Simriz® FFKM materials provide excellent resistance to a broad range of chemicals, including acids, solvents, fuels, and reactive gases, while also maintaining strong performance at elevated temperatures. These properties make Simriz® FFKM O-rings and seals ideal for applications where standard elastomers such as FKM, EPDM, or silicone would degrade or fail.


At Canyon Components, we supply Simriz® FFKM O-rings, gaskets, and custom parts, while also offering Canrez® FFKM as a high-performance alternative. Canrez® FFKM materials are engineered to deliver comparable chemical resistance and thermal performance, with the added benefits of strong availability, competitive pricing, and responsive lead times compared to Simriz®, Kalrez®, and Chemraz®. Our engineering team works closely with customers to identify the best material solution based on performance, cost, and supply requirements.


Whether you need standard AS568 O-rings, metric sizes, or fully custom FFKM components, Canyon Components provides expert support, material selection guidance, and custom manufacturing solutions for demanding sealing applications.


Common names include: FFKM, Perfluoroelastomer, Perfluorinated Rubber. Trade names: Simriz®, Canrez®, Kalrez®, Chemraz®, Parofluor®.
