<P>PROBLEM TO BE SOLVED: To provide an acrylic rubber composition expressing good vulcanizing characteristics, sufficient ordinary state physical properties and heat resistance only by primary vulcanization, to provide a vulcanizate obtained by vulcanization of the acrylic rubber composition, and to provide hoses, seals and rubber vibration isolators using the vulcanizate. Ž<P>SOLUTION: The acrylic rubber composition comprises 100 pts.mass acrylic rubber, 1-10 pts.mass specific maleimide compound, 0.1-2 pts.mass specific phenothiazine compound and 5-10 pts.mass peroxide. Decrease of cold resistance of the obtainable vulcanizate and mechanical properties after heat aging thereof can be prevented by adding ethylene or vinyl acetate to the acrylic rubber.
