-327 RED SILICONE 70D FDA O-RING

Part number S70FDA327 is an AS568-327 red Silicone 70 Shore A O-Ring with an inside diameter of 1.725 in (43.82 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.145 in (54.48 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Silicone delivers flexibility that holds at very low temperatures, physiological inertness and low toxicity. The material holds up against ozone and UV exposure, weathering, and many oxidizing chemicals. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). Exposure to steam above its rated range or hydrocarbon fuels and oils will shorten service life.

The compound meets FDA requirements for food contact under 21 CFR 177.2600. Maintenance and OEM teams specify it across medical devices, pharmaceutical manufacturing, and ovens and heated equipment.
