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 and excellent electrical insulating properties. Expect good resistance to weathering, many oxidizing chemicals, and ozone and UV exposure. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Verify compatibility before use with steam above its rated range or hydrocarbon fuels and oils.
This o-ring meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. It sees regular use in medical devices, pharmaceutical manufacturing, and sanitary process lines.
This item is sold individually under part number S70FDA207. Unit weight is approximately 0.749 g and nominal inside diameter is listed as 9/16 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
