568-032 FLUOROSILICONE 70 DURO ORINGS

The FS70032 is an AS568-032 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring measuring an inside diameter of 1.864 in (47.35 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.004 in (50.9 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists aromatic fuels and jet fuel, chlorinated solvents, and petroleum oils. That behavior comes from the compound itself: Fluorosilicone (FVMQ) is widely chosen for a very wide service temperature range, excellent ozone and UV stability. Continuous operating temperature is published at -80°F (-62.2°C) to 350°F (176.7°C). It is not the right choice where brake fluids or hydrazine are present.

You will find this material specified across military ground vehicles, aerospace and defense, and aviation fuel systems.

This item is sold individually under part number FS70032. Unit weight is approximately 0.6051 g and nominal inside diameter is listed as 1 7/8 inch.
