568-027 FLUOROSILICONE 70 DURO ORING

FS70027 is an AS568-027 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring measuring an inside diameter of 1.301 in (33.05 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.441 in (36.6 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Fluorosilicone (FVMQ) is valued for silicone's low-temperature flexibility combined with fuel resistance and the standard choice for static aerospace fuel system seals. Expect good resistance to ozone and weathering, petroleum oils, and extreme cold. The material carries a published service range of -80°F (-62.2°C) to 350°F (176.7°C). Exposure to ketones or hydrazine will shorten service life.

You will find this material specified across military ground vehicles, aerospace and defense, and aviation fuel systems.

FS70027 ships individually. Unit weight is approximately 0.4072 g. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
