*568-164 FLUOROSILICONE 70 DURO ORINGS

Part number FS70164 is an AS568-164 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring measuring an inside diameter of 6.237 in (158.42 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 6.443 in (163.65 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists chlorinated solvents, extreme cold, and aromatic fuels and jet fuel. That behavior comes from the compound itself: Fluorosilicone (FVMQ) is known for good compression set resistance in static duty, excellent ozone and UV stability. The material carries a published service range of -80°F (-62.2°C) to 350°F (176.7°C).

You will find this material specified across high-altitude equipment, aviation fuel systems, and military ground vehicles.

FS70164 ships individually. Unit weight is approximately 4.2716 g and nominal inside diameter is listed as 6 1/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
