-394 RED SILICONE 70D FDA O-RING

Part number S70FDA394 is an AS568-394 red Silicone 70 Shore A O-Ring with an inside diameter of 24.94 in (633.48 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 25.36 in (644.14 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against ozone and UV exposure, many oxidizing chemicals, and dry heat. That behavior comes from the compound itself: Silicone is specified for very good compression set resistance across its range and an exceptionally wide service temperature range. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where hydrocarbon fuels and oils or concentrated acids are present.

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