Fluoroelastomer compositions comprising fluoroelastomers having copolymerized units of a nitrile-containing cure site monomer are cured with certain hydrazide curatives. The hydrazide is of the general formula R1C(O)NHNHR2, wherein R1 is alkyl, aryl, benzyl, heterocycle, fluoroalkyl, or H; R2 is H, alkyl, aryl, heterocycle, CO2R3, C(O)H, or CH2R4; R3 is alkyl, CH2R4, aryl, benzyl, or heterocycle; and R4 is a fluoroalkyl group.
