  • Patent number: 5728974
    Abstract: A grommet for sealing an opening in a partition which having a main body and a fixture. The body has a flexible pocket surrounding the opening into which a skirt on the fixture enters. When the assembled grommet is placed under compression, the skirt forces the pocket against the edge of the opening, thereby providing a reliable waterproof seal. At the same time, the pressure urges a sealing lip on the main body against the partition to provide a watertight seal. Thus, the device is capable of producing two seals, rather than a single seal as is to be found in the prior art. The grommet is of particular use in connection with automotive vehicles.
