The S70FDA422 is an AS568-422 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 4.1 in (104.14 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.65 in (118.11 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists many oxidizing chemicals, dry heat, and ozone and UV exposure. Silicone is known for excellent electrical insulating properties and very good compression set resistance across its range. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where steam above its rated range or hydrocarbon fuels and oils are present.
