4MM CS X 120MM ID RED SILICONE 70D

Part number S4X120 is a red Silicone 70 Shore A O-Ring supplied with an inside diameter of 120 mm (4.724 in), a cross section of 4 mm (0.157 in), and an outside diameter of 128 mm (5.04 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against many oxidizing chemicals, ozone and UV exposure, and weathering. That behavior comes from the compound itself: Silicone is valued for physiological inertness and low toxicity, flexibility that holds at very low temperatures. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Applications involving abrasive dynamic service or concentrated acids call for a different compound.

This o-ring meets FDA requirements for food contact. You will find this material specified across food and beverage processing, medical devices, and ovens and heated equipment.

Order part number S4X120, sold individually. Unit weight is approximately 6.86 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
