SFDA3X27 is a red Silicone 70 Shore A O-Ring measuring an inside diameter of 27 mm (1.063 in), a cross section of 3 mm (0.118 in), and an outside diameter of 33 mm (1.3 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.
Silicone is specified here for flexibility that holds at very low temperatures and very good compression set resistance across its range. The material holds up against many oxidizing chemicals, ozone and UV exposure, and dry heat. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. Applications involving abrasive dynamic service or hydrocarbon fuels and oils call for a different compound.
This o-ring meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. It sees regular use in food and beverage processing, sanitary process lines, and pharmaceutical manufacturing.
Stocked as SFDA3X27 and sold individually. Unit weight is approximately 0.0064 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
