ABSTRACT OF THE DISCLOSURE This invention relates to the use of particular urethane or urethane/sulfur cured acrylonitrile-butadiene elastomers in systems wherein a vulcanizate component with resistance to oxidized (sour) hydrocarbon fuel is desired, that is in systems wherein a vulcanizate functions in contact with hydrocarbon fuel having oxidation products therein. The vulcanizate composition consists essentially of the reaction produces of (i) 100 parts by weight o an acrylonitrile-butadiene copolymer and (ii) a curative comprising 1-10 parts by weight of a urethane curing agent, wherein the urethane curing agent is the reaction product of a nitrosophenol and a diisocyanate. The curative may additionally comprise sulfur.
