Ordered as S70404, this is an AS568-404 red Silicone 70 Shore A O-Ring built to an inside diameter of 1.85 in (46.99 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 2.4 in (60.96 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.
The material holds up against weathering, dry heat, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone is specified for very good compression set resistance across its range, physiological inertness and low toxicity. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where abrasive dynamic service or hydrocarbon fuels and oils are present.
It sees regular use in sanitary process lines, electronics and electrical enclosures, and ovens and heated equipment.
This item is sold individually under part number S70404. Unit weight is approximately 9.12 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
