*568-267 FLUOROSILICONE 70 DURO ORING

The FS70267 is an AS568-267 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring with an inside diameter of 8.234 in (209.14 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 8.512 in (216.2 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Fluorosilicone (FVMQ) is specified here for standard choice for static aerospace fuel system seals and very wide service temperature range. The material holds up against chlorinated solvents, extreme cold, and petroleum oils. Service temperature is rated from -80°F (-62.2°C) through 350°F (176.7°C). It is not the right choice where ketones or brake fluids are present.

Common environments for this compound include aerospace and defense, aviation fuel systems, and high-altitude equipment.

Stocked as FS70267 and sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
