The cap member (26) is fixedly connected within the end portion (16). A gasket (34) perfects a fluid tight seal between the shell (12) and the cap member (26). The cap member (26) includes a radially outwardly projecting protrusion having an outer surface (36,38). The gasket (34) is disposed about the protrusion. The end portion (16) of the shell (12) is crimped around the protrusion for preventing axially inward and outward movement of the cap member (26) relative to the shell (12) and compressing the gasket (34) against the outer surface (36,38) of the protrusion.
