What Are Viton Seals?
Viton seals are high-performance sealing elements made from FKM material, a fluoroelastomer known for its durability and resistance to extreme conditions. They are widely used in industries such as automotive, aerospace, chemical processing, and energy, where standard rubber seals would fail. Thanks to their excellent resistance to heat, chemicals, and fuels, Viton seals are considered one of the most reliable sealing solutions on the market.
Properties of FKM Material
FKM material, also called fluoroelastomer, is characterized by its high fluorine content, which gives it unique performance features:
Exceptional resistance to oils, fuels, solvents, and aggressive chemicals.
Ability to withstand high operating temperatures, often up to 200–260 °C depending on the grade.
Excellent resistance to aging, ozone, and UV exposure.
Low gas permeability, making it ideal for vacuum or high-pressure applications.
Wide range of hardness levels, usually between Shore A 60 and 90, to adapt to different sealing requirements.
These properties make FKM seals a preferred choice wherever long-lasting performance and reliability are required.
Viton Gasket Solutions
A Viton gasket is designed to create a tight, secure seal between two surfaces, even under extreme operating conditions. Unlike standard rubber gaskets, a Viton gasket resists swelling, cracking, or deformation when exposed to fuels, oils, and aggressive chemicals. They are particularly valued in applications involving high pressure and fluctuating temperatures, ensuring reliable sealing performance over long service lives.
Viton O Rings for Demanding Applications
Viton o rings are among the most common sealing components made from FKM material. Their versatility allows them to be used in pumps, valves, fuel systems, and hydraulic equipment. Viton o rings maintain their elasticity even under constant exposure to heat and aggressive media, reducing the risk of leakage and downtime. For industries where safety and efficiency are critical, Viton o rings are an essential choice.
Benefits of FKM Seals Compared to Standard Materials
When compared to seals made of NBR or EPDM, FKM seals provide significantly higher resistance to chemical attack and elevated temperatures. While the initial investment in Viton products may be higher, their long service life and reduced need for replacement lower overall maintenance costs. This cost-effectiveness, combined with unmatched performance, explains why Viton seals, Viton gaskets, and Viton o rings are widely used across demanding industries.
Whether in the form of Viton seals, Viton gasket, or Viton o rings, sealing solutions made from FKM material offer outstanding durability and reliability. With their ability to resist heat, chemicals, and pressure, FKM seals have become the industry standard for demanding applications where failure is not an option.
