2.5MM CS X 38MM ID RED SILICONE 70D

Ordered as S2.5X38, this is a red Silicone 70 Shore A O-Ring measuring an inside diameter of 38 mm (1.496 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 43 mm (1.69 in). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists many oxidizing chemicals, weathering, and dry heat. That behavior comes from the compound itself: Silicone is widely chosen for flexibility that holds at very low temperatures, physiological inertness and low toxicity. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Exposure to concentrated acids or hydrocarbon fuels and oils will shorten service life.

This item meets FDA requirements for food contact. Maintenance and OEM teams specify it across medical devices, electronics and electrical enclosures, and sanitary process lines.
