The S70FDA377 is an AS568-377 red Silicone 70 Shore A O-Ring measuring an inside diameter of 9.975 in (253.37 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 10.395 in (264.03 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
It resists many oxidizing chemicals, weathering, and ozone and UV exposure. That behavior comes from the compound itself: Silicone is known for physiological inertness and low toxicity, flexibility that holds at very low temperatures. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Exposure to abrasive dynamic service or hydrocarbon fuels and oils will shorten service life.
This item meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. You will find this material specified across medical devices, pharmaceutical manufacturing, and ovens and heated equipment.
Stocked as S70FDA377 and sold individually. Unit weight is approximately 25.29 g and nominal inside diameter is listed as 10 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. 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.
