A method for manufacturing a gasket that is reinforced by a metal band, which is completely encapsulated within the elastomeric material of the gasket. The metal band is formed with spaced-apart dimples stamped into its inner surface, causing raised projections to form on the outer surface of the metal band. When the metal band is placed in a mold, the raised projections on its outer surface cause the metal band to be spaced apart from the inner wall of the mold. Elastomeric material is then injected into the mold and is able to completely encapsulate the metal band. The gasket is cured and then removed from the mold.
