APG stocks the S70031, an AS568-031 red Silicone 70 Shore A O-Ring with an inside diameter of 1.739 in (44.17 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.879 in (47.73 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
It resists many oxidizing chemicals, dry heat, and ozone and UV exposure. That behavior comes from the compound itself: Silicone is widely chosen 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). Applications involving hydrocarbon fuels and oils or abrasive dynamic service call for a different compound.
Typical settings include pharmaceutical manufacturing, food and beverage processing, and sanitary process lines.
This item is sold individually under part number S70031. Unit weight is approximately 0.527 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
