FS70018 is an AS568-018 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring built to an inside diameter of 0.739 in (18.77 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.879 in (22.33 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

As a material, Fluorosilicone (FVMQ) is valued for the standard choice for static aerospace fuel system seals, excellent ozone and UV stability. The compound resists extreme cold, chlorinated solvents, and petroleum oils. Rated temperature range runs from -80°F (-62.2°C) to 350°F (176.7°C) in continuous service. Exposure to ketones or brake fluids will shorten service life.
