-909 RED SILICONE 70D FDA O-RING

Part number S70FDA909 is an AS568-909 red Silicone 70 Shore A O-Ring with an inside diameter of 0.706 in (17.93 mm), a cross section of 0.097 in (2.46 mm), and an outside diameter of 0.9 in (22.86 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists weathering, dry heat, and many oxidizing chemicals. Silicone offers flexibility that holds at very low temperatures and very good compression set resistance across its range. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Exposure to steam above its rated range or hydrocarbon fuels and oils will shorten service life.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. It sees regular use in electronics and electrical enclosures, medical devices, and pharmaceutical manufacturing.
