Part number SFDA2X43 is a red Silicone 70 Shore A O-Ring built to an inside diameter of 43 mm (1.693 in), a cross section of 2 mm (0.079 in), and an outside diameter of 47 mm (1.85 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load. Source specification: FDA Compliant TO 21CFR Sec 177-2600, Metric O-RING.
The compound resists extreme heat and cold, ozone and UV exposure, and many oxidizing chemicals. Silicone offers flexibility that holds at very low temperatures, physiological inertness and low toxicity. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. Exposure to steam above its rated range or abrasive dynamic service will shorten service life.
The compound meets FDA requirements for food contact under 21 CFR 177.2600. Common environments for this compound include ovens and heated equipment, pharmaceutical manufacturing, and medical devices.
