There is disclosed an easy to install grommet device for protecting conduit passing through a wall opening and for providing an air seal between the conduit and the edge of the wall around the wall opening. The grommet device has a relatively stiff fastener portion with projections extending therefrom and locking devices at the ends of the projections for engaging the edges of the wall around the wall opening. An elastomeric seal portion receives the projections and has an aperture of smaller dimensions than the outside dimensions of the conduit.
