Abstract: Electrically conductive sealing elements include a resilient grommet portion and an electrically conductive portion imbedded in a portion of the grommet so as to provide EMI protection and/or an electrically conductive path from a workpiece to a panel into which the grommet can be inserted.

Abstract: A grommet disposed in a panel hole to prevent a fire from spreading from one panel side to the other has a pair of flaps defining a socket for nesting in the panel hole in a closely fit relationship. Preferably one flap is longer than the other and is disposed against the panel surface. The grommet has an inner peripheral surface, preferably annular, defining a hollow central opening with a radius less than that of the cable so as to receive and retain the cable even with changes in cable positioning. The grommet has a fire resistant chemical composition which becomes resiliently flattened upon the cable disposition in the grommet opening. One flap is bent toward the other with the panel withdrawn from the socket and is resiliently pressed against the panel with the panel in the socket. The grommet includes, in the section with the larger flap, a fire resistant fabric (e.g. ceramic) impregnated and coated with the fire resistant chemical composition (e.g. silicone with an approximately 55 Rockwell hardness).
