Viton seals are widely used in aerospace, automotive, oil and gas, chemical, and power generation industries.

What Are Viton Seals?

Viton rubber, a high-performance fluoroelastomer, is a synthetic rubber known for its outstanding thermal stability and chemical resistance. Viton seals serve as critical components for joining surfaces, acting as barriers to prevent leaks of liquids, gases, and particles.

Our Viton seals come in a variety of forms, including:

  • Cut gaskets

  • Washers

  • O-rings

  • Extruded profiles

  • Cord

Many of our Viton seals are also supplied with self-adhesive backing for easy placement and secure positioning.
