3MM CS X 8MM ID RED SILICONE 70D

Part number SFDA3X8 is a red Silicone 70 Shore A O-Ring with an inside diameter of 8 mm (0.315 in), a cross section of 3 mm (0.118 in), and an outside diameter of 14 mm (0.55 in). An o-ring compresses into its gland to block fluid or gas migration across a joint. This item is further identified as FDA Compliant TO 21CFR Sec 177-2600, Metric O-RING.

The material holds up against dry heat, weathering, and extreme heat and cold. That behavior comes from the compound itself: Silicone is widely chosen for physiological inertness and low toxicity, an exceptionally wide service temperature range. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where concentrated acids or abrasive dynamic service are present.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. Typical settings include medical devices, pharmaceutical manufacturing, and ovens and heated equipment.
