*568-129 FLUOROSILICONE 70 DURO ORINGS

APG stocks the FS70129, an AS568-129 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring with an inside diameter of 1.549 in (39.34 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.755 in (44.58 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

This material stands up to petroleum oils, aromatic fuels and jet fuel, and chlorinated solvents. That behavior comes from the compound itself: Fluorosilicone (FVMQ) offers a very wide service temperature range and good compression set resistance in static duty. Published continuous service range is -80°F (-62.2°C) to 350°F (176.7°C). It should not be specified for service in brake fluids or hydrazine.

Maintenance and OEM teams specify it across military ground vehicles, high-altitude equipment, and aerospace and defense.
