*568-327 FLUOROSILICONE 70 DURO ORINGS

Ordered as FS70327, this is an AS568-327 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring measuring an inside diameter of 1.725 in (43.82 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.145 in (54.48 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Fluorosilicone (FVMQ) is specified here for standard choice for static aerospace fuel system seals and silicone's low-temperature flexibility combined with fuel resistance. This material stands up to petroleum oils, chlorinated solvents, and extreme cold. Service temperature is rated from -80°F (-62.2°C) through 350°F (176.7°C). It is not the right choice where brake fluids or ketones are present.

Maintenance and OEM teams specify it across military ground vehicles, aerospace and defense, and high-altitude equipment.
