This o-ring is supplied in red Silicone 70 Shore A with an inside diameter of 13 mm (0.512 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 18 mm (0.71 in), catalogued under part number S2.5X13. It remains the most cost-effective sealing element available for pressurized assemblies.
The material holds up against many oxidizing chemicals, dry heat, and ozone and UV exposure. That behavior comes from the compound itself: Silicone delivers very good compression set resistance across its range and excellent electrical insulating properties. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Applications involving concentrated acids or steam above its rated range call for a different compound.
This o-ring meets FDA requirements for food contact. It sees regular use in pharmaceutical manufacturing, food and beverage processing, and sanitary process lines.
Stocked as S2.5X13 and sold individually. Unit weight is approximately 0.336 g. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
