Nitrile rubber is still the most widely used elastomer for O-rings.
It has an excellent resistance to petroleum based oils and fuels, silicone greases, hydraulic fluids, water and alcohols. It has a great balance of working properties such as low compression set, high tensile strength, high abrasion resistance, combined with a low material costs.
