This o-ring is supplied in red Silicone 70 Shore A built to an inside diameter of 47 mm (1.85 in), a cross section of 3 mm (0.118 in), and an outside diameter of 53 mm (2.09 in), catalogued under part number S3X47. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
The material holds up against many oxidizing chemicals, weathering, and dry heat. That behavior comes from the compound itself: Silicone is known 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). Exposure to hydrocarbon fuels and oils or concentrated acids will shorten service life.
The compound meets FDA requirements for food contact. Typical settings include electronics and electrical enclosures, ovens and heated equipment, and sanitary process lines.
Reference part number S3X47 when ordering; the item is sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
