Ordered as SFDA2X17, this is a red Silicone 70 Shore A O-Ring with an inside diameter of 17 mm (0.669 in), a cross section of 2 mm (0.079 in), and an outside diameter of 21 mm (0.83 in). The o-ring remains the most cost-effective sealing element available for pressurized assemblies. This item is further identified as FDA Compliant TO 21CFR Sec 177-2600, Metric O-RING.
Expect good resistance to many oxidizing chemicals, weathering, and dry heat. That behavior comes from the compound itself: Silicone is valued for physiological inertness and low toxicity, very good compression set resistance across its range. 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, is metal detectable for HACCP and foreign-body control programs. It sees regular use in electronics and electrical enclosures, pharmaceutical manufacturing, and sanitary process lines.
Order part number SFDA2X17, sold individually. Unit weight is approximately 0.0064 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
