The FS70144 is an AS568-144 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring supplied with an inside diameter of 2.487 in (63.17 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.693 in (68.4 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
As a material, Fluorosilicone (FVMQ) offers good compression set resistance in static duty and a very wide service temperature range. The material holds up against aromatic fuels and jet fuel, petroleum oils, and chlorinated solvents. Service temperature is rated from -80°F (-62.2°C) through 350°F (176.7°C). Exposure to ketones or high-temperature dynamic service will shorten service life.
Common environments for this compound include aerospace and defense, aviation fuel systems, and high-altitude equipment.
Stocked as FS70144 and sold individually. Unit weight is approximately 1.7715 g. Check the compound against your process media, pressure and temperature before committing to a design.
