*568-212 FLUOROSILICONE 70 DURO ORINGS

The FS70212 is an AS568-212 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring built to an inside diameter of 0.859 in (21.82 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.137 in (28.88 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Fluorosilicone (FVMQ) is widely chosen for a very wide service temperature range and silicone's low-temperature flexibility combined with fuel resistance. It resists extreme cold, petroleum oils, and aromatic fuels and jet fuel. Rated temperature range runs from -80°F (-62.2°C) to 350°F (176.7°C) in continuous service. Exposure to ketones or hydrazine will shorten service life.

Typical settings include high-altitude equipment, aerospace and defense, and military ground vehicles.
