568-011 FLUOROSILICONE 70 DURO ORINGS

Ordered as FS70011, this is an AS568-011 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring with an inside diameter of 0.301 in (7.65 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.441 in (11.2 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to ozone and weathering, chlorinated solvents, and aromatic fuels and jet fuel. That behavior comes from the compound itself: Fluorosilicone (FVMQ) is valued for silicone's low-temperature flexibility combined with fuel resistance and good compression set resistance in static duty. Continuous operating temperature is published at -80°F (-62.2°C) to 350°F (176.7°C). It is not the right choice where high-temperature dynamic service or ketones are present.

Maintenance and OEM teams specify it across high-altitude equipment, aviation fuel systems, and aerospace and defense.

Order part number FS70011, sold individually. Unit weight is approximately 0.1115 g. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
