-918 RED SILICONE 70D FDA O-RING

Part number S70FDA918 is an AS568-918 red Silicone 70 Shore A O-Ring measuring an inside diameter of 1.355 in (34.42 mm), a cross section of 0.116 in (2.95 mm), and an outside diameter of 1.587 in (40.31 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against dry heat, many oxidizing chemicals, and weathering. That behavior comes from the compound itself: Silicone is known for flexibility that holds at very low temperatures, physiological inertness and low toxicity. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Verify compatibility before use with steam above its rated range or hydrocarbon fuels and oils.

The compound meets FDA requirements for food contact under 21 CFR 177.2600. You will find this material specified across sanitary process lines, ovens and heated equipment, and food and beverage processing.

S70FDA918 ships individually. Unit weight is approximately 1.157 g and nominal inside diameter is listed as 1 1/8 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.
