568-130 FLUOROSILICONE 70 DURO ORINGS

FS70130 is an AS568-130 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring with an inside diameter of 1.612 in (40.94 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.818 in (46.18 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, Fluorosilicone (FVMQ) is specified for excellent ozone and UV stability, the standard choice for static aerospace fuel system seals. Expect good resistance to chlorinated solvents, petroleum oils, and extreme cold. The material carries a published service range of -80°F (-62.2°C) to 350°F (176.7°C). Applications involving hydrazine or ketones call for a different compound.

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

FS70130 ships individually. Unit weight is approximately 1.1368 g and nominal inside diameter is listed as 1 5/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
