Silicone Rubber O-Rings

Silicone O-Rings provide good insulating properties

Silicone (VMQ) O-rings are go-to solutions for environmental seals, offering excellent ozone and weathering resistance, sealability across a wide range of temperatures, and good chemical resistance. FDA and medically compliant compounds are also widely available. Silicone makes a great static seal, but is not recommended for dynamic sealing due to relatively poor mechanical performance (low tensile strength, tear strength, and abrasion resistance).

Features & Benefits:

  • Resistant to UV and ozone exposure, weathering, and fungus
  • Low compression set protects against seal failure and extends maintenance intervals for static seals
  • Commonly available in FDA compliant and medical grade compounds
  • Temperature range: –65°F to 500°F (-54° to 260°C)

Markets & Applications

  • Medical
  • Pharmaceutical
  • Food & Beverage
  • Electronics
  • Weather-Proofing
