-021 RED SILICONE 70D O-RING

Part number S70021 is an AS568-021 red Silicone 70 Shore A O-Ring measuring an inside diameter of 0.926 in (23.52 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.066 in (27.08 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Silicone is specified here for flexibility that holds at very low temperatures and very good compression set resistance across its range. It resists many oxidizing chemicals, dry heat, and extreme heat and cold. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Exposure to concentrated acids or abrasive dynamic service will shorten service life.

Common environments for this compound include electronics and electrical enclosures, medical devices, and sanitary process lines.
