-218 RED SILICONE 70D FDA O-RING

Part number S70FDA218 is an AS568-218 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 1.234 in (31.34 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.512 in (38.4 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The material holds up against many oxidizing chemicals, dry heat, and weathering. That behavior comes from the compound itself: Silicone delivers excellent electrical insulating properties and an exceptionally wide service temperature range. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. Exposure to concentrated acids or abrasive dynamic service will shorten service life.

This item meets FDA requirements for food contact under 21 CFR 177.2600. Common environments for this compound include electronics and electrical enclosures, ovens and heated equipment, and pharmaceutical manufacturing.
