-241 RED SILICONE 70D FDA O-RING

S70FDA241 is an AS568-241 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 3.859 in (98.02 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.137 in (105.08 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to ozone and UV exposure, weathering, and extreme heat and cold. That behavior comes from the compound itself: Silicone delivers very good compression set resistance across its range and excellent electrical insulating properties. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Applications involving hydrocarbon fuels and oils or abrasive dynamic service call for a different compound.

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

Order part number S70FDA241, sold individually. Unit weight is approximately 4.553 g and nominal inside diameter is listed as 3 7/8 inch. Review your operating media and conditions against this specification before installation.
