*568-266 FLUOROSILICONE 70 DURO ORINGS

Part number FS70266 is an AS568-266 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring measuring an inside diameter of 7.984 in (202.79 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 8.262 in (209.85 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to petroleum oils, ozone and weathering, and aromatic fuels and jet fuel. That behavior comes from the compound itself: Fluorosilicone (FVMQ) offers good compression set resistance in static duty, excellent ozone and UV stability. Published continuous service range is -80°F (-62.2°C) to 350°F (176.7°C). Verify compatibility before use with brake fluids or ketones.

Common environments for this compound include aviation fuel systems, high-altitude equipment, and aerospace and defense.
