Viton® FAQs

3/4" thick 75 durometer viton rubber roll

What are the main benefits of Viton® rubber?

The primary advantages of Viton® include exceptional heat resistance, outstanding chemical resistance, excellent compression set, good mechanical properties, and superior aging characteristics compared to most other elastomers.

Where is Viton® rubber commonly used?

Viton® is widely used in automotive, aerospace, chemical processing, oil and gas, and industrial applications where exposure to high temperatures, aggressive chemicals, and petroleum-based products is common.

How does Viton® compare to other rubber materials?

Viton® outperforms most conventional elastomers in high-temperature environments and chemical exposure scenarios. While it has a higher initial cost than materials like EPDM, Neoprene, or Nitrile, its longer service life and superior performance in harsh conditions often result in better long-term value.

What thickness should I choose?

The appropriate thickness depends on your specific application. Thinner sheets (1/64" to 1/8") are typically used for gaskets and seals in applications with tight tolerance requirements. Thicker sheets (3/16" to 1") are suitable for more demanding mechanical applications requiring additional durability or compression resistance.

Can you provide custom cut gaskets?

Yes, we offer custom cutting services for all our Viton® rubber sheets. Contact our technical team to discuss your specific dimensional requirements.

Do you provide material certifications?

We provide certificates of conformance upon request.

Is Viton® resistant to UV and ozone?

Yes, Viton® offers good resistance to UV radiation, ozone, and weathering, making it suitable for outdoor applications where exposure to environmental elements is a concern.

What temperatures can Viton® rubber withstand?

Standard Viton® rubber has a service temperature range of -20°F to +400°F (-28°C to +204°C), though special compounds can be formulated for specific temperature requirements.

Chemical Properties of Viton

Excellent Resistance To:

  • Aliphatic, aromatic, and halogenated hydrocarbons
  • Oils and lubricants (mineral and synthetic)
  • Fuels (gasoline, diesel, biodiesel, aviation)
  • Many acids (including sulfuric and nitric)
  • Steam and high-temperature water
  • Hydraulic fluids
  • Many chlorinated solvents
  • Petroleum-based products

Limited Resistance To:

  • Ketones (acetone, MEK)
  • Low molecular weight esters and ethers
  • Hot amines and alkalis
  • Some phosphate ester-based fluids

Not Recommended For:

  • Strong alkalis
  • Low molecular weight organic acids
  • Glycol-based brake fluids
  • Hot amine compounds
  • Hot polar solvents

Permeation Resistance

Viton® offers low permeability to gases and fluids, making it an excellent material for containment applications where preventing leakage is critical.

Installation & Handling Guidelines

Cutting and Fabrication

  • Use sharp, clean cutting tools to prevent tearing or jagged edges
  • For precision cutting, use a water jet or die cutting process
  • When cutting thicker sheets, support the material adequately to prevent distortion
  • Clean tools between cuts to prevent contamination

Surface Preparation

  • Ensure mating surfaces are clean, dry, and free of debris before installation
  • For best adhesion when bonding, lightly abrade the surface and clean with an appropriate solvent
  • Allow any cleaning solvents to fully evaporate before installation

Installation Best Practices

  • Do not over-compress gaskets or seals made from Viton®
  • Typical compression should be between 15% and 30% of original thickness
  • Use appropriate torque specifications when installing Viton® gaskets
  • Allow for thermal expansion in high-temperature applications
  • When using fasteners, distribute compression force evenly

Storage Recommendations

  • Store in a cool, dry environment away from direct sunlight
  • Keep away from ozone sources (electric motors, mercury vapor lamps)
  • Store flat to prevent distortion
  • Avoid contact with incompatible materials
  • Optimal storage temperature range: 50°F to 80°F

Safety Considerations

  • Wear appropriate protective equipment when handling
  • Avoid machining or grinding cured Viton® in a way that creates dust
  • Ventilate area properly if heating Viton® above 400°F, as harmful vapors may be released at very high temperatures

  • Cost Benefit Analysis

    While Viton® has a higher initial cost than standard elastomers, its exceptional durability and resistance properties typically result in lower total cost of ownership through reduced maintenance, decreased downtime, longer service life, and improved safety in critical applications.

  • Maintenance & Care

    Viton® requires minimal maintenance when properly installed. Perform periodic inspections for wear and clean with mild soap and water or compatible solvents. Avoid petroleum-based cleaners on components exposed to high temperatures.

  • Manufacturing Process

    Our Viton® sheets are manufactured using advanced calendering processes with strict quality control procedures including durometer testing, visual inspection, and dimensional verification to ensure industry standard compliance.

  • Material Grade Selection Guide

    We offer multiple Viton® grades for specific applications: standard grades for general use, high-temperature grades (above 400°F), low-temperature grades, and specialty formulations for specific chemical resistance profiles.
