Minor Rubber produces Viton and FKM fluoroelastomer parts for engineers and procurement teams who require reliable performance under extreme thermal and chemical conditions. Viton is a registered trademark of The Chemours Company and represents one of the most widely specified fluoroelastomer brands in industrial manufacturing. Our facility is equipped to produce Viton and FKM parts through both molding and extruding processes, giving customers a single manufacturing source for precision fluoroelastomer components built to exact specifications.
Extreme Heat and Chemical Resistance in a Single Elastomer
The defining advantage of Viton and FKM fluoroelastomers is their ability to maintain mechanical integrity in environments that would degrade virtually any other rubber compound. These materials offer continuous high temperature resistance up to 600°F and exceptional compatibility with a broad range of aggressive chemicals including aliphatic, aromatic, and halogenated hydrocarbons, acids, and animal and vegetable oils. When a project demands reliable sealing or isolation performance in the presence of both elevated temperatures and chemical exposure simultaneously, Viton and FKM are consistently the material of choice for design engineers across demanding industries.
Viton and FKM Components We Manufacture
Minor Rubber produces Viton and FKM parts across several product categories. Our manufacturing capabilities allow us to supply both standard configurations and highly specialized custom geometries depending on your application requirements.
Seals and Gaskets
Seals and gaskets represent the most widely specified application for Viton and FKM across virtually every industry that uses fluoroelastomers. The material's exceptional resistance to chemical attack and thermal degradation makes it the preferred compound for critical sealing applications where standard elastomers cannot be reliably used. Our facility produces Viton seals including refrigerator door seals and sealing strips for a wide range of industrial applications.
Molded Viton Components
Compression molding, transfer molding, and injection molding allow Minor Rubber to produce complex custom Viton geometries beyond what extrusion alone can achieve. Custom molded FKM components are frequently specified for fluid handling systems, industrial equipment, and defense applications requiring precise tolerances and full material traceability. This expertise also extends to smaller components like custom Viton bumpers, tips, and appliance feet, which protect sensitive equipment from impact and vibration in data center environments.
Extruded Profiles and Tubing
We manufacture Viton and FKM extruded rubber profiles for sealing and protective applications that require precise cross-sectional geometry and consistent chemical resistance along the full length of the part. Some of the fluoroelastomer extrusion profiles we commonly produce include:
Rubber Grommets
Our rubber grommets in Viton and FKM provide reliable pass-through protection and sealing in environments where both chemical exposure and elevated temperatures are present. This is a less commonly available product form for fluoroelastomers and represents a core manufacturing strength at Minor Rubber. Some of the Viton grommet configurations we produce include:

Industries That Specify Viton and FKM Components
The combination of high-temperature stability and broad chemical resistance makes Viton and FKM the preferred fluoroelastomer across aerospace, electronics, chemical processing, and oil and gas applications. Engineers in these sectors consistently specify FKM compounds when standard elastomers cannot reliably perform under simultaneous exposure to elevated temperatures and aggressive chemicals. Minor Rubber regularly manufactures custom fluoroelastomer components for customers across all of these industries:

FAQs
What is the difference between Viton and FKM?
Viton and FKM are closely related but not exactly the same. FKM is the ASTM designation for the broader family of fluoroelastomers, while Viton is a specific brand name within that family owned by The Chemours Company. All Viton rubber is FKM, but not all FKM rubber is Viton. For most engineering and procurement applications the performance characteristics are essentially equivalent. Minor Rubber works with both to meet your specific project requirements.
What temperature range can Viton rubber parts withstand?
Viton and FKM components manufactured by Minor Rubber can withstand continuous high temperature usage between 400°F and 600°F, making them well suited for engine compartments, industrial processing equipment, and other elevated temperature environments. Low temperature performance is generally limited to approximately -10°F, which is one of the recognized tradeoffs of this material compared to silicone for extreme cold applications.
How do I know if Viton is compatible with my application's chemicals?
The best starting point is a chemical compatibility chart, which outlines how FKM performs against a broad range of fluids, solvents, and acids. Viton and FKM generally perform excellently against mineral oils, fuels, hydraulic fluids, aliphatic and aromatic hydrocarbons, and concentrated acids.
