The SFDA2X8 is a red Silicone 70 Shore A O-Ring supplied with an inside diameter of 8 mm (0.315 in), a cross section of 2 mm (0.079 in), and an outside diameter of 12 mm (0.47 in). This o-ring remains the most cost-effective sealing element available for pressurized assemblies. Additional detail on this item: FDA Compliant TO 21CFR Sec 177-2600, Metric O-RING.
The material holds up against weathering, ozone and UV exposure, and dry heat. That behavior comes from the compound itself: Silicone is widely chosen for an exceptionally wide service temperature range and very good compression set resistance across its range. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). Applications involving steam above its rated range or concentrated acids call for a different compound.
The compound meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. You will find this material specified across medical devices, ovens and heated equipment, and pharmaceutical manufacturing.
Stocked as SFDA2X8 and sold individually. Unit weight is approximately 0.0064 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
