Silicone O-rings are made from a synthetic elastomer composed of silicon, oxygen, hydrogen, and carbon. They are widely used for their excellent flexibility, high-temperature resistance, and exceptional aging properties. Silicone O-rings offer great thermal stability, low toxicity, and resistance to weathering, ozone, and UV exposure, making them ideal for medical, automotive, and food-grade applications. Many silicone compounds are **FDA-compliant**, making them suitable for food and pharmaceutical uses.

Silicone Recommended Uses

Medical and pharmaceutical applications, food and beverage processing, automotive components, aerospace industries, high-temperature sealing applications, and electrical insulation.

Silicone Not Recommended

Petroleum-based oils, fuels, concentrated acids, alkalis, ketones, and steam under high pressure.

Silicone Limitations

  • Not resistant to petroleum-based fluids and fuels.
  • Lower mechanical strength compared to other elastomers.
  • Not ideal for applications requiring high tear and abrasion resistance.
  • Can swell or degrade when exposed to certain chemicals and oils.
Silicone Usable Temperature Range

-85 to 450°F (-65 to 232°C)

Silicone Also Known As

Silicone Rubber, VMQ (Vinyl Methyl Silicone), Polysiloxane.
