FKM Oil Seal

FKM oil seals from Shenshou City Sanshi Rubber Co., Ltd are manufactured from fluoroelastomer compounds designed for dynamic sealing in high-temperature and chemically aggressive environments. The seals are produced to standard dimensions based on ISO 6194-1 and DIN 3760, with inner diameters ranging from 10 mm to 200 mm and cross-sections of 3 mm to 7 mm, as specified in the product listing. These seals are not coated or plated, relying on the inherent properties of the FKM compound for performance.

The base material is a fluorocarbon rubber with a typical fluorine content of 66% to 68%, which provides resistance to mineral oils, fuels, and hydraulic fluids up to 200°C. This grade is standard for industrial applications in automotive, aerospace, and chemical processing sectors. Unlike generic nitrile seals, FKM maintains elasticity and dimensional stability under prolonged thermal cycling, reducing the risk of extrusion or hardening over time. The material is free from phthalates and heavy metal stabilisers, aligning with RoHS guidelines for industrial components.

These seals are used in pumps, compressors, gearboxes, and engine crankshafts where fluid containment is critical. Buyers include manufacturers of industrial machinery, automotive aftermarket suppliers, and OEMs in the oil and gas sector. Packaging is typically in sealed polyethylene bags with cardboard outer cartons, with quantities per carton ranging from 100 to 500 pieces depending on size. Minimum order quantities are not stated in the listing and must be confirmed directly with the supplier.
