This o-ring is supplied in red Silicone 70 Shore A measuring an inside diameter of 56 mm (2.205 in), a cross section of 3 mm (0.118 in), and an outside diameter of 62 mm (2.44 in), catalogued under part number S3X56. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.
It resists extreme heat and cold, weathering, and dry heat. That behavior comes from the compound itself: Silicone is specified for excellent electrical insulating properties and flexibility that holds at very low temperatures. 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 concentrated acids or steam above its rated range are present.
The compound meets FDA requirements for food contact. Maintenance and OEM teams specify it across food and beverage processing, medical devices, and electronics and electrical enclosures.
Order part number S3X56, sold individually. Unit weight is approximately 1.81 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
