Static sealing element for acoustically decoupled add-on pieces

A housing closing cover comprising:

• a carrier element having a generally planar bottom surface to be positioned in direct abutment against a mating component and having an opening in said carrier element;
• a fluid seal mounted in said opening of said carrier element, said seal having a static annular axial sealing lip facing in the axial direction of said opening adjacent an edge of said opening, said axial sealing lip extending axially outwardly from said planar bottom surface of said carrier element to provide a static face seal between said housing and the mating component, and including an annular radial sealing lip attached to said axial sealing lip and extending in a radial direction from said axial sealing lip for sealing a member projecting through said opening, and wherein said radial sealing lip extends axially inwardly in relation to said planar bottom surface and is supported for angular and radial movement relative to said carrier element without significantly impairing the sealing established by said radial sealing lip about the member projecting through the opening.
