The FS70154 is an AS568-154 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring supplied with an inside diameter of 3.737 in (94.92 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.943 in (100.15 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Fluorosilicone (FVMQ) delivers the standard choice for static aerospace fuel system seals and a very wide service temperature range. This material stands up to chlorinated solvents, petroleum oils, and extreme cold. Rated temperature range runs from -80°F (-62.2°C) to 350°F (176.7°C) in continuous service. Verify compatibility before use with high-temperature dynamic service or ketones.

Maintenance and OEM teams specify it across aerospace and defense, aviation fuel systems, and high-altitude equipment.
