This o-ring is supplied in red Silicone 70 Shore A measuring an inside diameter of 20 mm (0.787 in), a cross section of 2 mm (0.079 in), and an outside diameter of 24 mm (0.94 in), catalogued under part number S2X20. It remains the most cost-effective sealing element available for pressurized assemblies.
Silicone is specified here for physiological inertness and low toxicity, flexibility that holds at very low temperatures. The material holds up against ozone and UV exposure, extreme heat and cold, and dry heat. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Applications involving steam above its rated range or abrasive dynamic service call for a different compound.
The compound meets FDA requirements for food contact. Typical settings include food and beverage processing, sanitary process lines, and medical devices.
Order part number S2X20, sold individually. Unit weight is approximately 0.302 g. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
