The FS70469 is an AS568-469 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring measuring an inside diameter of 19.955 in (506.86 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 20.505 in (520.83 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Fluorosilicone (FVMQ) is known for excellent ozone and UV stability, silicone's low-temperature flexibility combined with fuel resistance. This material stands up to petroleum oils, chlorinated solvents, and extreme cold. Continuous operating temperature is published at -80°F (-62.2°C) to 350°F (176.7°C). Applications involving high-temperature dynamic service or hydrazine call for a different compound.
It sees regular use in aviation fuel systems, high-altitude equipment, and aerospace and defense.
This item is sold individually under part number FS70469. Unit weight is approximately 97.266 g. Check the compound against your process media, pressure and temperature before committing to a design.
