-221 RED SILICONE 70D FDA O-RING

This o-ring is supplied in AS568-221 red Silicone 70 Shore A measuring an inside diameter of 1.421 in (36.09 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.699 in (43.15 mm), catalogued under part number S70FDA221. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Silicone is specified for excellent electrical insulating properties and very good compression set resistance across its range. Expect good resistance to many oxidizing chemicals, ozone and UV exposure, and extreme heat and cold. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. Applications involving steam above its rated range or hydrocarbon fuels and oils call for a different compound.

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

Order part number S70FDA221, sold individually. Unit weight is approximately 1.708 g. Check the compound against your process media, pressure and temperature before committing to a design.
