-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, is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across pharmaceutical manufacturing, sanitary process lines, and ovens and heated equipment.
