568-348 FLUOROSILICONE 70 DURO ORINGS

FS70348 is an AS568-348 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring measuring an inside diameter of 4.35 in (110.49 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.77 in (121.16 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Fluorosilicone (FVMQ) is valued for the standard choice for static aerospace fuel system seals and good compression set resistance in static duty. It resists petroleum oils, extreme cold, and ozone and weathering. The material carries a published service range of -80°F (-62.2°C) to 350°F (176.7°C). Verify compatibility before use with high-temperature dynamic service or brake fluids.

You will find this material specified across high-altitude equipment, aerospace and defense, and military ground vehicles.

Stocked as FS70348 and sold individually. Unit weight is approximately 12.65 g. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
