Grommet

The present disclosure relates to a grommet for mounting in an opening of a panel or similar structure. The grommet includes a main body that defines a central passage and one or more flexible retaining arms arranged along an outer wall of the main body. The retaining arms are configured to flex during installation and engage the surrounding structure to hold the grommet in place. A sealing material is provided between the retaining arms and the main body to close gaps while still allowing the arms to flex as needed. This arrangement provides improved resistance to rotation after installation and helps maintain effective sealing between the interior and exterior of the grommet, reducing the likelihood of fluid, dust, or air passing through the mounted opening.
