This o-ring is supplied in AS568-349 red Silicone 70 Shore A measuring an inside diameter of 4.475 in (113.67 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.895 in (124.33 mm), catalogued under part number S70MD349. It remains the most cost-effective sealing element available for pressurized assemblies.
The compound resists many oxidizing chemicals, ozone and UV exposure, and dry heat. Silicone offers very good compression set resistance across its range and an exceptionally wide service temperature range. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). Exposure to hydrocarbon fuels and oils or concentrated acids will shorten service life.
This item is metal detectable for HACCP and foreign-body control programs. Typical settings include electronics and electrical enclosures, sanitary process lines, and medical devices.
Reference part number S70MD349 when ordering; the item is sold individually. Nominal inside diameter is listed as 4 1/2 inch. Review your operating media and conditions against this specification before installation.
