APG stocks the FS70137, an AS568-137 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring supplied with an inside diameter of 2.05 in (52.07 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.256 in (57.3 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Fluorosilicone (FVMQ) is known for good compression set resistance in static duty and a very wide service temperature range. It resists ozone and weathering, chlorinated solvents, and aromatic fuels and jet fuel. Rated temperature range runs from -80°F (-62.2°C) to 350°F (176.7°C) in continuous service. Applications involving ketones or brake fluids call for a different compound.

Maintenance and OEM teams specify it across military ground vehicles, aerospace and defense, and aviation fuel systems.
