This o-ring is supplied in AS568-317 red Silicone 70 Shore A measuring an inside diameter of 0.912 in (23.16 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.332 in (33.83 mm), catalogued under part number S70MD317. It remains the most cost-effective sealing element available for pressurized assemblies.
As a material, Silicone is widely chosen for very good compression set resistance across its range and an exceptionally wide service temperature range. The compound resists weathering, many oxidizing chemicals, and ozone and UV exposure. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Exposure to abrasive dynamic service or steam above its rated range will shorten service life.
This o-ring is metal detectable for HACCP and foreign-body control programs. You will find this material specified across ovens and heated equipment, food and beverage processing, and sanitary process lines.
Stocked as S70MD317 and sold individually. Review your operating media and conditions against this specification before installation.
