-033 RED SILICONE 70D FDA O-RING

Part number S70FDA033 is an AS568-033 red Silicone 70 Shore A O-Ring measuring an inside diameter of 1.989 in (50.52 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.129 in (54.08 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Silicone is valued for very good compression set resistance across its range and an exceptionally wide service temperature range. This material stands up to many oxidizing chemicals, weathering, and dry heat. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). It is not the right choice where hydrocarbon fuels and oils or concentrated acids are present.

The compound meets FDA requirements for food contact under 21 CFR 177.2600. It sees regular use in ovens and heated equipment, pharmaceutical manufacturing, and sanitary process lines.
