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, is metal detectable for HACCP and foreign-body control programs. Typical settings include medical devices, pharmaceutical manufacturing, and ovens and heated equipment.
Order part number SFDA3X8, sold individually. Unit weight is approximately 0.0064 g. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
