568-223 FLUOROSILICONE 70 DURO ORINGS

FS70223 is an AS568-223 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring supplied with an inside diameter of 1.609 in (40.87 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.887 in (47.93 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

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

Typical settings include aviation fuel systems, aerospace and defense, and military ground vehicles.

Reference part number FS70223 when ordering; the item is sold individually. Unit weight is approximately 2.088 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.
