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

As a material, Silicone is valued for very good compression set resistance across its range and an exceptionally wide service temperature range. Expect good resistance to many oxidizing chemicals, dry heat, and weathering. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). It should not be specified for service in abrasive dynamic service or hydrocarbon fuels and oils.

You will find this material specified across electronics and electrical enclosures, food and beverage processing, and sanitary process lines.
