A method of forming a sealing member comprising a metal body having a resilient material thereon and a resiliently deflectable lip member extending inwardly from the edge of a hole in the metal body for sealingly contacting a surface, including the steps of: (a) forming a hole in a generally flat, comparatively thin metal sheet; (b) coating at least one side of the metal sheet with a resilient material in such a manner that the resilient material at least covers the hole; (c) cutting away a predetermined amount of resilient material inwardly of the edge of the hole to form the resiliently deflectable lip member, and (d) forming the metal sheet and resilient coating into a predetermined shape defining the outer configuration for the sealing member.
