Ordered as S70FDA371, this is an AS568-371 red Silicone 70 Shore A O-Ring built to an inside diameter of 8.475 in (215.27 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 8.895 in (225.93 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
As a material, Silicone is valued for an exceptionally wide service temperature range and very good compression set resistance across its range. It resists weathering, ozone and UV exposure, and many oxidizing chemicals. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where abrasive dynamic service or hydrocarbon fuels and oils are present.
The compound meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. It sees regular use in medical devices, food and beverage processing, and sanitary process lines.
