568-325 FLUOROSILICONE 70 DURO ORINGS

The FS70325 is an AS568-325 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring measuring an inside diameter of 1.475 in (37.47 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.895 in (48.13 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists petroleum oils, ozone and weathering, and extreme cold. That behavior comes from the compound itself: Fluorosilicone (FVMQ) offers a very wide service temperature range and silicone's low-temperature flexibility combined with fuel resistance. Published continuous service range is -80°F (-62.2°C) to 350°F (176.7°C). It is not the right choice where hydrazine or ketones are present.

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

This item is sold individually under part number FS70325. Unit weight is approximately 4.8125 g and nominal inside diameter is listed as 1 1/2 inch.
