What is a Fluorine Rubber Oil Seal?

Fluorine rubber, also known as FKM or Viton, is a synthetic polymer known for its outstanding thermal and chemical resistance. Its properties make it an ideal material for oil seals used in various industries, including automotive, aerospace, and machinery.

Characteristics of Fluorine Rubber Oil Seals

  • High Temperature Resistance: These seals can withstand temperatures ranging from -20°C to 250°C, making them suitable for high-heat applications.
  • Chemical Resistance: They are highly resistant to oils, fuels, and various chemicals, which extends their lifespan and reliability.
  • Durability: Fluorine rubber oil seals have excellent wear resistance, reducing the frequency of maintenance and replacements.
  • Low Compression Set: This feature helps maintain sealing performance over time.

Common Applications of Fluorine Rubber Oil Seals

Fluorine rubber oil seals are widely used across various sectors due to their physical and chemical properties. Here are some common applications:

  • Automotive Industry: Used in engines, gearboxes, and hydraulic systems.
  • Aerospace: Essential for sealing in fuel systems and hydraulic circuits due to their resistance to extreme conditions.
  • Food Processing: In food-grade applications where hygiene and chemical resistance are critical.
  • Pharmaceuticals: Used in equipment that requires sterile conditions.

Typical Dimensions and Sizes

Fluorine rubber oil seals come in various sizes, designed to cater to different needs. Common dimensions include:
