This o-ring is supplied in AS568-208 blue Fluorosilicone (FVMQ) 70 Shore A measuring an inside diameter of 0.609 in (15.47 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.887 in (22.53 mm), catalogued under part number FS70208. It compresses into its gland to block fluid or gas migration across a joint.

As a material, Fluorosilicone (FVMQ) is valued for good compression set resistance in static duty and a very wide service temperature range. The compound resists ozone and weathering, aromatic fuels and jet fuel, and chlorinated solvents. Published continuous service range is -80°F (-62.2°C) to 350°F (176.7°C). Applications involving hydrazine or ketones call for a different compound.

Typical settings include aerospace and defense, aviation fuel systems, and high-altitude equipment.

This item is sold individually under part number FS70208. Unit weight is approximately 0.8172 g and nominal inside diameter is listed as 5/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
