SFDA3X75 is a red Silicone 70 Shore A O-Ring built to an inside diameter of 75 mm (2.953 in), a cross section of 3 mm (0.118 in), and an outside diameter of 81 mm (3.19 in). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware. Supplementary detail from the product record: FDA Compliant TO 21CFR Sec 177-2600, Metric O-RING.
This material stands up to many oxidizing chemicals, weathering, and ozone and UV exposure. That behavior comes from the compound itself: Silicone delivers excellent electrical insulating properties and flexibility that holds at very low temperatures. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. Applications involving hydrocarbon fuels and oils or abrasive dynamic service call for a different compound.
The compound meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. Typical settings include electronics and electrical enclosures, pharmaceutical manufacturing, and medical devices.
Reference part number SFDA3X75 when ordering; the item is sold individually. Unit weight is approximately 0.0064 g. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
