S70338 is an AS568-338 red Silicone 70 Shore A O-Ring built to an inside diameter of 3.1 in (78.74 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.52 in (89.41 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
The compound resists dry heat, weathering, and ozone and UV exposure. Silicone offers flexibility that holds at very low temperatures, physiological inertness and low toxicity. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Verify compatibility before use with abrasive dynamic service or hydrocarbon fuels and oils.
Common environments for this compound include medical devices, electronics and electrical enclosures, and pharmaceutical manufacturing.
Stocked as S70338 and sold individually. Unit weight is approximately 8.28 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
