Silicone O-rings

Features of Silicone O-rings

The following information will help you decide if these O-rings are well-suited for your applications or not.

• Silicone made O-rings can provide reliable service at temperatures as low as -70 oF and as high as 390 oF.
• Silicone material offers excellent resistance to compression set.
• Silicone elastomers have weak abrasion and tear resistance, as well as low tensile strength. However, they exhibit excellent weathering, as well as heat resistance.
• Silicone elastomers strongly resist corona, ozone, and heat resistance, as well as excellent dielectric stability.
• Silicone shows excellent flexibility at low temperatures. However, they are generally platinum cured for improving flexibility. Platinum cured silicone O-rings have better flexibility than non-cured ones, and a very low volatility. Platinum cured silicone O-rings are used in medical equipment, food and beverage applications and more because they don’t impart any odor, taste, or color.
• Silicone made O-rings are recommended for applications where they come in contact with:
  • Hot air
  • Engine and Transmission Oils
  • Animal and Vegetable Oils
  • Greases
  • Break Fluids
  • Fire Resistant Hydraulic Fluids
• Silicone O-rings are not recommended for applications where they come in contact with :
  • Superheated water/steam
  • Acids and alkalis
  • Aromatic mineral oils
  • Hydrocarbon based fuels
  • Aromatic hydrocarbons
