-020 RED SILICONE 70D FDA O-RING

S70FDA020 is an AS568-020 red Silicone 70 Shore A O-Ring with an inside diameter of 0.864 in (21.95 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.004 in (25.5 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to weathering, extreme heat and cold, and ozone and UV exposure. That behavior comes from the compound itself: Silicone is known for excellent electrical insulating properties and very good compression set resistance across its range. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where concentrated acids or abrasive dynamic service are present.

This item meets FDA requirements for food contact under 21 CFR 177.2600. Maintenance and OEM teams specify it across pharmaceutical manufacturing, sanitary process lines, and ovens and heated equipment.
