-202 RED SILICONE 70D FDA O-RING

Part number S70FDA202 is an AS568-202 red Silicone 70 Shore A O-Ring built to an inside diameter of 0.234 in (5.94 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.512 in (13 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Silicone is specified here for excellent electrical insulating properties and very good compression set resistance across its range. The compound resists many oxidizing chemicals, dry heat, and ozone and UV exposure. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where concentrated acids or steam above its rated range are present.

The compound meets FDA requirements for food contact under 21 CFR 177.2600. Common environments for this compound include sanitary process lines, medical devices, and electronics and electrical enclosures.

S70FDA202 ships individually. Unit weight is approximately 0.431 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
