An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Silicone delivers flexibility that holds at very low temperatures, physiological inertness and low toxicity. The material holds up against ozone and UV exposure, weathering, and many oxidizing chemicals. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). Exposure to steam above its rated range or hydrocarbon fuels and oils will shorten service life.
