APG stocks the FS70014, an AS568-014 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring supplied with an inside diameter of 0.489 in (12.42 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.629 in (15.98 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Fluorosilicone (FVMQ) is specified here for good compression set resistance in static duty and silicone's low-temperature flexibility combined with fuel resistance. The compound resists aromatic fuels and jet fuel, petroleum oils, and ozone and weathering. Published continuous service range is -80°F (-62.2°C) to 350°F (176.7°C). Applications involving hydrazine or brake fluids call for a different compound.

Maintenance and OEM teams specify it across aviation fuel systems, high-altitude equipment, and military ground vehicles.

Order part number FS70014, sold individually. Unit weight is approximately 0.1719 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
