-223 RED SILICONE 70D FDA O-RING

APG stocks the S70FDA223, an AS568-223 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 1.609 in (40.87 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.887 in (47.93 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to weathering, dry heat, and ozone and UV exposure. That behavior comes from the compound itself: Silicone delivers an exceptionally wide service temperature range and excellent electrical insulating properties. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Applications involving steam above its rated range or concentrated acids call for a different compound.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. Maintenance and OEM teams specify it across sanitary process lines, medical devices, and ovens and heated equipment.

This item is sold individually under part number S70FDA223. Unit weight is approximately 1.886 g and nominal inside diameter is listed as 1 5/8 inch. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
