FFKM Rubber O Ring Perfluoroelastomer Materials Provide the Highest Temperature and Acid Resistance
Crafted from perfluoroelastomer (FFKM), these O rings deliver unmatched performance in extreme environments, with continuous operating temperatures ranging from -20°C to +327°C. They resist degradation from aggressive media like concentrated sulfuric acid (98%), nitric acid (70%), and chlorinated solvents, outlasting standard FKM seals by 3x in harsh chemical processing conditions.
Ideal for semiconductor manufacturing, oil refining, and pharmaceutical equipment, their non-porous surface prevents contamination and ensures zero permeation of volatile organic compounds (VOCs). FDA-compliant grades are available for food-contact applications, while ISO 2852-certified dimensions guarantee precise fit in pumps, valves, and flanges. Reduce downtime with seals that maintain elasticity and pressure resistance (up to 500 bar) across thermal cycles.
