In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists extreme heat and cold, many oxidizing chemicals, and ozone and UV exposure. Silicone is widely chosen for flexibility that holds at very low temperatures, physiological inertness and low toxicity. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). Verify compatibility before use with abrasive dynamic service or concentrated acids.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. You will find this material specified across pharmaceutical manufacturing, sanitary process lines, and medical devices.
