APG stocks the S70FDA207, an AS568-207 red Silicone 70 Shore A O-Ring built to an inside diameter of 0.546 in (13.87 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.824 in (20.93 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

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 under 21 CFR 177.2600. 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.
