A sealing apparatus is provided for sealing an automotive component extending between an engine compartment and a passenger compartment of an automobile. The sealing apparatus includes a pass-through mount component configured to house the automotive component. An outer seal component is configured to rigidly mount to a wall structure separating the passenger compartment from the engine compartment and to elastically contact a platform region of one end of the pass-through mount structure. An inner seal component is configured to elastically couple to the outer seal component within the passenger compartment and to elastically couple to one end of the pass-through mount component.
