-473 RED SILICONE 70D FDA O-RING

This o-ring is supplied in AS568-473 red Silicone 70 Shore A built to an inside diameter of 23.94 in (608.08 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 24.49 in (622.05 mm), catalogued under part number S70FDA473. It remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to extreme heat and cold, ozone and UV exposure, and dry heat. That behavior comes from the compound itself: Silicone is specified for very good compression set resistance across its range and flexibility that holds at very low temperatures. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Exposure to steam above its rated range or hydrocarbon fuels and oils will shorten service life.

This item meets FDA requirements for food contact under 21 CFR 177.2600. Typical settings include food and beverage processing, medical devices, and ovens and heated equipment.

Reference part number S70FDA473 when ordering; the item is sold individually. Unit weight is approximately 100.1 g and nominal inside diameter is listed as 24 inch.
