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

Silicone is specified here for very good compression set resistance across its range, physiological inertness and low toxicity. It resists many oxidizing chemicals, extreme heat and cold, and weathering. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Applications involving hydrocarbon fuels and oils or concentrated acids call for a different compound.
