Viton O-Ring Kits

  • Viton O-Ring Kits

Viton® material is a synthetic rubber and fluoropolymer elastomer that withstands high temperatures and provides excellent resistance to acid, flame, oil, ozone, and weather. The durability and chemical resistance of Viton O-rings also provides additional protection against seal failure and can reduce maintenance frequency.

These properties make Viton ideal for use in advanced fuel and engine systems and other applications involving exposure to acids, fuels, and extreme temperatures. Industries that typically use Viton O rings include automotive, aerospace, chemical processing, and general industrial.

Viton O-Rings Provide Exceptional Resistance to Chemicals & High Temperatures

Viton is categorized as an FKM material (fluorocarbon elastomer) under ASTM D1418 and ISO 1629 standards and has a significantly higher density than most other types of rubber. The material also has good tensile strength and tear resistance and exhibits good to excellent dynamic resistance and set resistance.

  • Operating temperature range: -20°F to 400°F (-29°C to 204°C)
  • Density: over 1,800 kg/m3
  • Fluorine content range: 66-70%

There are several advantages to choosing Viton over other elastomers, especially for high-temperature applications. The primary advantage is that its mechanical properties, including oil and chemical resistance, are unaffected by elevated temperatures.  Viton FKM also displays good compression resistance and impermeability at high temperatures, where other elastomers often become brittle and prone to breakage.
