*568-029 FLUOROSILICONE 70 DURO ORINGS

FS70029 is an AS568-029 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring built to an inside diameter of 1.489 in (37.82 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.629 in (41.38 mm). In service, 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) is valued for a very wide service temperature range, excellent ozone and UV stability. Expect good resistance to chlorinated solvents, petroleum oils, and extreme cold. The material carries a published service range of -80°F (-62.2°C) to 350°F (176.7°C). Verify compatibility before use with brake fluids or hydrazine.

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

FS70029 ships individually. Unit weight is approximately 0.4589 g and nominal inside diameter is listed as 1 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
