-004 RED SILICONE 70D FDA O-RING

Part number S70FDA004 is an AS568-004 red Silicone 70 Shore A O-Ring built to an inside diameter of 0.07 in (1.78 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.21 in (5.33 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against extreme heat and cold, ozone and UV exposure, and dry heat. That behavior comes from the compound itself: Silicone is widely chosen for flexibility that holds at very low temperatures and excellent electrical insulating properties. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). Applications involving steam above its rated range or concentrated acids call for a different compound.

This item meets FDA requirements for food contact under 21 CFR 177.2600. You will find this material specified across ovens and heated equipment, sanitary process lines, and medical devices.

Order part number S70FDA004, sold individually. Unit weight is approximately 0.04 g and nominal inside diameter is listed as 5/64 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
