摘要： A grommet configured to pass through a vehicle wall and an acoustic mat is provided. The grommet includes first and second sealing segments, a mounting segment, and a pass-through segment. A flange configured to abut the vehicle wall extends from the first sealing segment. The pass-through segment has a NVH flap that is configured to abut the acoustic mat. The grommet has a grommet installation coupling that includes a mounting hole in the flange for receiving a mounting stud that extends from the vehicle wall and an engagement member that engages the mounting stud. The engagement member applies an installation force to the flange, which moves the grommet longitudinally from a first installation position to a second installation position and pushes the NVH flap against the acoustic mat so that the NVH flap is deflected back toward the flange as the grommet moves to the second installation position.
