A sealing grommet is utilized to form a seal for articles such as electrical wires passing through the outer case of a refrigerator cabinet, the insulation, particularly foam insulation, between the outer case and the inner liner of the cabinet, and the inner liner. The grommet includes a substantially cylindrically shaped hollow body of a relatively rigid material disposed between the inner liner and the outer wall with a core of a relatively soft material supported by the inner surface of the body and secured thereto by glue, for example. Each of the body and the core is split longitudinally to receive the electrical wires with the core having a central longitudinal passage extending therethrough for an interference fit with the electrical wires. An integral mounting flange and a plurality of spaced locking lugs cooperate to mount the body on the inner liner. A separate grommet can be utilized at the outer case with the core having a sufficient length to extend into engagement with the adjacent surface of the separate grommet so that the core has a seal with the outer case through the separate grommet having a seal with the outer case. The body could have a mounting flange, similar to the mounting flange cooperating with the inner liner, for cooperation with the outer case rather than a separate grommet being employed.

In combination, a refrigerator cabinet having inner and outer walls, insulation between the inner and outer walls, an opening in each of the inner and outer walls, the insulation having a passage to provide communication between the openings in the inner and outer walls, a grommet disposed in the passage in the insulation, said grommet comprising: a longitudinal, hollow body of a relatively rigid material having a single longitudinal passage extending therethrough; a core of a relatively flexible material disposed within said longitudinal passage in said body for support by said body and in air sealing relation with said body, said core having a longitudinal passage extending therethrough; each of said body and said core being slit longitudinally to enable said passage of said core to receive at least one article therein for passage therethrough; mounting means secured to one end of said body and attaching said body to one of the inner and outer walls of the refrigerator cabinet in air sealing relation therewith; and said core being in air sealing relation with the other of the inner and outer walls of the refrigerator cabinet to prevent any contact of the insultion with any article passing through said passage of said core.
