Abstract: A grommet for insertion into an opening of a radiator header plate may have a cylindrical outer surface having a body outer diameter, an annular shoulder proximate a top surface and extending outwardly beyond the outer surface of the body, and an annular bead proximate a bottom surface of the body and extending outwardly beyond the outer surface of the body and have a bead outer diameter that is greater than the body outer diameter. The annular bead may include a tapered bottom portion having a decreasing outer diameter as the tapered bottom portion extends downwardly toward the bottom surface of the body, with the tapered bottom portion terminating with a bottom outer diameter that is less than the body outer diameter.
