Applications of FKM rubber gaskets

FKM gasket variants, including Viton gasket and FKM flange gasket, are typically specified for sealing fuel, oil and aggressive hydrocarbon systems in automotive, aerospace and petrochemical assemblies, and for static flange and pipe joint applications where chemical resistance and elevated-temperature stability are priorities. The fluoroelastomer formulation is often chosen because it offers low permeation, resistance to fuels, oils and many solvents, and dimensional stability under thermal stress.

FKM may be less suitable where very low-temperature flexibility, prolonged steam or hot-water exposure, or extreme dynamic sealing with high extrusion risk are the primary requirements; in such cases alternative elastomers or engineered polymers are often preferred. Product options appear in the fkm-rubber and rubber-gaskets collections.

FAQ

What are FKM rubber gaskets?

FKM rubber gaskets are cut from a synthetic fluoroelastomer and provide static sealing for applications that require chemical and thermal resistance. They are suitable for environments exposed to oils, fuels, hydraulic fluids and many common solvents, with final suitability dependent on the specific FKM grade and operating conditions.

What industries use FKM rubber gaskets?

FKM rubber gaskets are primarily used in the automotive, aerospace and petrochemical sectors. They are also specified in other industrial systems where resistance to hydrocarbons and elevated temperatures is required.

Are FKM and Viton the same?

Viton is a registered trade name for a type of fluoroelastomer that is commonly used interchangeably with the term FKM. Performance can vary between manufacturers and grades, so confirm the exact material grade for critical applications.

Can FKM rubber gaskets be used for flange connections?

FKM flange gaskets are commonly used for static flange seals where chemical and thermal resistance is needed. Suitability depends on gasket design, flange specification and service conditions; contact the technical team for grade selection and installation guidance.
