*568-133 FLUOROSILICONE 70 DURO ORINGS

This o-ring is supplied in AS568-133 blue Fluorosilicone (FVMQ) 70 Shore A measuring an inside diameter of 1.799 in (45.69 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.005 in (50.93 mm), catalogued under part number FS70133. It compresses into its gland to block fluid or gas migration across a joint.

The compound resists extreme cold, aromatic fuels and jet fuel, and petroleum oils. Fluorosilicone (FVMQ) is widely chosen for silicone's low-temperature flexibility combined with fuel resistance and good compression set resistance in static duty. Published continuous service range is -80°F (-62.2°C) to 350°F (176.7°C). Verify compatibility before use with hydrazine or brake fluids.

Common environments for this compound include aviation fuel systems, high-altitude equipment, and military ground vehicles.

FS70133 ships individually. Nominal inside diameter is listed as 1 13/16 inch. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
