This o-ring is supplied in AS568-389 red Silicone 70 Shore A with an inside diameter of 19.953 in (506.81 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 20.373 in (517.47 mm), catalogued under part number S70FDA389. It delivers dependable bidirectional sealing in a compact groove envelope.

It resists weathering, dry heat, and extreme heat and cold.

Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Verify compatibility before use with abrasive dynamic service or steam above its rated range.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. You will find this material specified across ovens and heated equipment, electronics and electrical enclosures, and pharmaceutical manufacturing.
