568-216 FLUOROSILICONE 70 DURO ORINGS

This o-ring is supplied in AS568-216 blue Fluorosilicone (FVMQ) 70 Shore A supplied with an inside diameter of 1.109 in (28.17 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.387 in (35.23 mm), catalogued under part number FS70216. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to extreme cold, aromatic fuels and jet fuel, and chlorinated solvents. That behavior comes from the compound itself: Fluorosilicone (FVMQ) is valued for the standard choice for static aerospace fuel system seals and good compression set resistance in static duty. Rated temperature range runs from -80°F (-62.2°C) to 350°F (176.7°C) in continuous service. It is not the right choice where brake fluids or ketones are present.

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

Order part number FS70216, sold individually. Unit weight is approximately 1.4947 g. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
