ABSTRACT:
A sealing device (20) includes a layer of sealant (22) for sealing an internal surface (30) of a hollow member (34). The internal surface is nonparallel to the open end of the hollow member, and has an aperture pattern (44) for receiving at least one substrate (40) extending from a support surface across the hollow member. The layer of sealant is disposed adjacent the internal surface and supported by a backing (24) having an aperture pattern corresponding to the aperture pattern of the internal surface. The backing is spaced from the support surface and is movably supported inside the hollow member. The layer of sealant is adhered to the front surface of the backing to form a self-supporting article that can be easily positioned into the hollow member. One or more substrates can be inserted through the support surface across the hollow member, through the apertures in the backing and the layer of sealant, and through the apertures on the internal surface. To seal the internal surface and the substrates, a compression member is interposed between the support surface and the low friction rear surface of the backing. The compression member is generally noncompressible and is sized to apply generally uniform pressure on the backing and layer of sealant in sealing contact against the internal surface. The compression member includes an array of tooth-like cutouts that match the aperture pattern of the internal surface so that the compression member will not damage or otherwise interfere with the substrates during insertion and removal.
