FS70128 is an AS568-128 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring supplied with an inside diameter of 1.487 in (37.77 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.693 in (43 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Fluorosilicone (FVMQ) is specified here for silicone's low-temperature flexibility combined with fuel resistance and standard choice for static aerospace fuel system seals. It resists extreme cold, ozone and weathering, and aromatic fuels and jet fuel. Continuous operating temperature is published at -80°F (-62.2°C) to 350°F (176.7°C).

It sees regular use in aerospace and defense, military ground vehicles, and aviation fuel systems.

Stocked as FS70128 and sold individually. Unit weight is approximately 1.0957 g and nominal inside diameter is listed as 1 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
