In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
Fluorosilicone (FVMQ) is specified here for silicone's low-temperature flexibility combined with fuel resistance, excellent ozone and UV stability. Expect good resistance to extreme cold, petroleum oils, and chlorinated solvents. 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.
It sees regular use in high-altitude equipment, aerospace and defense, and military ground vehicles.
Stocked as FS70382 and sold individually. Unit weight is approximately 36.551 g. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
