Chemical properties Excellent resistance to hydrocarbons, fuels, mineral and synthetic oils and greases, and suitable for use with mineral-based 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.
