Fluorosilicone FVMQ - General grades

Fluorosilicone (FVMQ)

Chemical properties
Resistant to aliphatic and aromatic hydrocarbons, kerosene and petroleum fuels, mineral and synthetic oils and greases. Suitable for use with mineral-based, water/glycol and water/oil emulsion hydraulic fluids.

Typical operating temperatures
-60°C to +180°C continuous, or +200°C intermittent.

Fluid sealing duties
Widely used for static seals in aerospace fuel systems. Its more general use is limited by high gas permeability, low tensile strength and poor resistance to tear and abrasion. 

James Walker standard grades
Supplied in hardnesses of 60-80 IRHD.
