2.5MM CS X 20MM ID RED SILICONE 70D

Part number S2.5X20 is a red Silicone 70 Shore A O-Ring built to an inside diameter of 20 mm (0.787 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 25 mm (0.98 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against extreme heat and cold, weathering, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone is valued for flexibility that holds at very low temperatures and excellent electrical insulating properties. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where steam above its rated range or abrasive dynamic service are present.

This o-ring meets FDA requirements for food contact. It sees regular use in electronics and electrical enclosures, sanitary process lines, and medical devices.
