Ordered as S70400, this is an AS568-400 red Silicone 70 Shore A O-Ring built to an inside diameter of 1.35 in (34.29 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 1.9 in (48.26 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.
Expect good resistance to dry heat, extreme heat and cold, and ozone and UV exposure. That behavior comes from the compound itself: Silicone is widely chosen for excellent electrical insulating properties, physiological inertness and low toxicity. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Exposure to concentrated acids or abrasive dynamic service will shorten service life.
Common environments for this compound include sanitary process lines, electronics and electrical enclosures, and medical devices.
This item is sold individually under part number S70400. Nominal inside diameter is listed as 1 3/8 inch. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
