*568-447 FLUOROSILICONE 70 DURO ORING

This o-ring is supplied in AS568-447 blue Fluorosilicone (FVMQ) 70 Shore A built to an inside diameter of 8.975 in (227.97 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 9.525 in (241.94 mm), catalogued under part number FS70447. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against aromatic fuels and jet fuel, petroleum oils, and extreme cold. That behavior comes from the compound itself: Fluorosilicone (FVMQ) is widely chosen for good compression set resistance in static duty, excellent ozone and UV stability. Continuous operating temperature is published at -80°F (-62.2°C) to 350°F (176.7°C).

It sees regular use in high-altitude equipment, military ground vehicles, and aerospace and defense.

This item is sold individually under part number FS70447. Nominal inside diameter is listed as 9 inch. Review your operating media and conditions against this specification before installation.
