Thickness

This cork and nitrile rubber blend combines the compressibility of cork with the flexibility of rubber. HC60 performs well in torque or bolt-pressure flange gaskets, particularly in low-pressure situations. It has good oil and solvent resistance and is typically used for transformers, vehicle oil seals, gearbox seals, cover gaskets, and fluid seals.
