Made from high-performance fluorocarbon (FKM), these O-rings meet SAE standard AS568 inch sizing. They provide superior resistance to high pressures, temperatures, and a broader range of oils, fuels, and chemicals compared to nitrile O-rings. With excellent durability and low compression set, they are ideal for demanding automotive, aerospace, and industrial applications where nitrile O-rings may fall short. Not recommended for long-term use with brake fluid. Bulk discounts are available for large quantity purchases.
