-031 RED SILICONE 70D FDA O-RING

APG stocks the S70FDA031, 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.

This material stands up to extreme heat and cold, weathering, and dry heat. Silicone is specified for physiological inertness and low toxicity, very good compression set resistance across its range. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). Exposure to concentrated acids or abrasive dynamic service will shorten service life.

The compound meets FDA requirements for food contact under 21 CFR 177.2600. It sees regular use in food and beverage processing, medical devices, and sanitary process lines.
