S70FDA363 is an AS568-363 red Silicone 70 Shore A O-Ring with an inside diameter of 6.475 in (164.47 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.895 in (175.13 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to many oxidizing chemicals, dry heat, and weathering. Silicone is known for excellent electrical insulating properties and flexibility that holds at very low temperatures. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where hydrocarbon fuels and oils or concentrated acids are present.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. Maintenance and OEM teams specify it across sanitary process lines, pharmaceutical manufacturing, and food and beverage processing.
