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.
