-388 RED SILICONE 70D FDA O-RING

Part number S70FDA388 is an AS568-388 red Silicone 70 Shore A O-Ring with an inside diameter of 18.953 in (481.41 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 19.373 in (492.07 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against weathering, ozone and UV exposure, and dry heat. That behavior comes from the compound itself: Silicone is valued for very good compression set resistance across its range, physiological inertness and low toxicity. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Verify compatibility before use with hydrocarbon fuels and oils or abrasive dynamic service.

This item meets FDA requirements for food contact under 21 CFR 177.2600. It sees regular use in electronics and electrical enclosures, pharmaceutical manufacturing, and ovens and heated equipment.

Stocked as S70FDA388 and sold individually. Unit weight is approximately 47.64 g and nominal inside diameter is listed as 19 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
