This o-ring is supplied in AS568-122 blue Fluorosilicone (FVMQ) 70 Shore A measuring an inside diameter of 1.112 in (28.24 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.318 in (33.48 mm), catalogued under part number FS70122. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.
The compound resists ozone and weathering, petroleum oils, and chlorinated solvents. Fluorosilicone (FVMQ) is specified for silicone's low-temperature flexibility combined with fuel resistance and a very wide service temperature range. Continuous operating temperature is published at -80°F (-62.2°C) to 350°F (176.7°C). Applications involving brake fluids or hydrazine call for a different compound.
You will find this material specified across aerospace and defense, military ground vehicles, and aviation fuel systems.
Stocked as FS70122 and sold individually. Unit weight is approximately 0.8388 g and nominal inside diameter is listed as 1 1/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
