Essential Guide to Viton Gaskets and Seals

13 March 2020

Viton is a popular brand name of DuPont de Nemours, Inc. for synthetic rubber and fluoropolymer elastomer, which are typically used in O-rings, gaskets, seals, and other moulded or extruded products. One key property of using Viton fluoroelastomers is that they can perform and function well under extreme temperatures and harsh chemicals.

Uses and Material Grades

Materials from Viton can be used in a lot of industrial situations. They can be used in automotive and other transportation fuel applications that involve high concentrations of biodiesel. Some material grade of Viton gaskets and seals can even resist acidic biodiesel.

As mentioned, Viton gaskets and seals can be classified into material grades. These material grades or families vary in their resistance to permeation and property degradation that is caused by the exposure to chemicals and fluids.

  • Viton A: Viton A is also known as the commercial-grade of Viton gaskets and seals. It has a fluorine content of 66%. Gaskets and seals from this grade are mostly used for general purpose seals for automotive, aerospace, lubricants, and fuels.
  • Viton B: Comprised of 68% fluorine, gaskets and seals that belong to Viton B are normally used in chemical processing, utilities, and power industries.
  • Viton F:Viton F, which has 70% fluorine content, gaskets and seals are great for applications that make contact with automotive fuels, aqueous inorganic acids, water, and steam.
  • Viton Extreme:This type of gaskets and seals can withstand extreme and harsh chemical environments. They are normally used in automotive oil seals, aerospace fuels, and oil field applications.

Advantages of Viton Materials

One advantage of using Viton gaskets, seals, and other materials on industrial applications is that they can maintain good mechanical properties even if they are exposed to high temperatures. Exposure of Viton materials to a temperature ranging from 204°C to 316°C won’t drastically affect their overall elasticity

These Viton materials can also resist the effects of oil and chemical penetration and deterioration. Chemicals and fluids that Viton materials can withstand include oils, fuels, lubricants, and most mineral acids. Compared to any commercial rubber, materials from Viton can certainly provide the best fluid resistance in the market right now.

Aside from high temperatures, Viton materials can also resist compression. They can also withstand damaging elements in the environment such as atmospheric oxidation, sun, climatic conditions, fungus, and mould. Lastly, they possess good electrical properties and low burning properties.

Viton gaskets and seals can greatly help you with different industrial applications under high temperatures. To know more about their manufacturing process, you can visit us at Gasketech.
