**568-344 FLUOROSILICONE 70 DURO ORING

Part number FS70344 is an AS568-344 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring built to an inside diameter of 3.85 in (97.79 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.27 in (108.46 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Fluorosilicone (FVMQ) is valued for the standard choice for static aerospace fuel system seals and a very wide service temperature range. The compound resists chlorinated solvents, aromatic fuels and jet fuel, and ozone and weathering. Continuous operating temperature is published at -80°F (-62.2°C) to 350°F (176.7°C). Exposure to high-temperature dynamic service or brake fluids will shorten service life.

It sees regular use in aviation fuel systems, aerospace and defense, and military ground vehicles.
