568-215 FLUOROSILICONE 70 DURO ORINGS

APG stocks the FS70215, an AS568-215 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring measuring an inside diameter of 1.046 in (26.57 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.324 in (33.63 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to ozone and weathering, aromatic fuels and jet fuel, and extreme cold. That behavior comes from the compound itself: Fluorosilicone (FVMQ) is widely chosen for good compression set resistance in static duty and the standard choice for static aerospace fuel system seals. Continuous operating temperature is published at -80°F (-62.2°C) to 350°F (176.7°C). It is not the right choice where hydrazine or brake fluids are present.

Typical settings include aerospace and defense, military ground vehicles, and aviation fuel systems.

Stocked as FS70215 and sold individually. Unit weight is approximately 1.4363 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
