-373 RED SILICONE 70D FDA O-RING

This o-ring is supplied in AS568-373 red Silicone 70 Shore A measuring an inside diameter of 8.975 in (227.97 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 9.395 in (238.63 mm), catalogued under part number S70FDA373.

This material stands up to many oxidizing chemicals, extreme heat and cold, and dry heat. That behavior comes from the compound itself: Silicone is specified for very good compression set resistance across its range, physiological inertness and low toxicity. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where abrasive dynamic service or hydrocarbon fuels and oils are present.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. It sees regular use in electronics and electrical enclosures, medical devices, and ovens and heated equipment.
