FKM Fluorine Rubber Gasket (220–300°C)
High Temperature FKM Fluoroelastomer Gasket Manufacturer & Supplier
FKM Fluorine Rubber Gasket is a high-performance sealing solution manufactured from premium fluoroelastomer (FKM) compounds. Designed for demanding industrial environments, it offers exceptional resistance to high temperatures, oils, fuels, chemicals, solvents, ozone, and weathering. With a continuous operating temperature of up to 220°C and short-term resistance reaching 300°C (depending on the compound grade), FKM gaskets provide reliable long-term sealing performance in harsh operating conditions.
Compared with conventional rubber materials such as NBR, EPDM, or silicone, FKM delivers superior chemical resistance, lower compression set, and excellent durability under continuous thermal and chemical exposure. It is widely used in automotive, aerospace, chemical processing, oil & gas, semiconductor, and industrial equipment where sealing reliability is critical.
As a professional FKM gasket manufacturer, we provide standard and custom die-cut gaskets, precision washers, O-ring alternatives, and OEM sealing solutions for customers worldwide.
