3MM CS X 48MM ID RED SILICONE 70D

APG stocks the S3X48, a red Silicone 70 Shore A O-Ring measuring an inside diameter of 48 mm (1.89 in), a cross section of 3 mm (0.118 in), and an outside diameter of 54 mm (2.13 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to extreme heat and cold, ozone and UV exposure, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone is widely chosen for excellent electrical insulating properties, physiological inertness and low toxicity. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). Applications involving hydrocarbon fuels and oils or abrasive dynamic service call for a different compound.

This o-ring meets FDA requirements for food contact. Typical settings include food and beverage processing, ovens and heated equipment, and medical devices.

Order part number S3X48, sold individually. Unit weight is approximately 1.5759 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.
