Ordered as S70208, this is an AS568-208 red Silicone 70 Shore A O-Ring with an inside diameter of 0.609 in (15.47 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.887 in (22.53 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.
The compound resists dry heat, extreme heat and cold, and ozone and UV exposure. That behavior comes from the compound itself: Silicone offers very good compression set resistance across its range, physiological inertness and low toxicity. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). It should not be specified for service in concentrated acids or steam above its rated range.
Typical settings include food and beverage processing, ovens and heated equipment, and electronics and electrical enclosures.
Order part number S70208, sold individually. Unit weight is approximately 0.805 g and nominal inside diameter is listed as 5/8 inch. Review your operating media and conditions against this specification before installation.
