The stuffing tube assembly is used in a deck or bulkhead of a ship. The stuffing tube comprises a cable having insulation on a surface thereof, a metallic shielding jacket, and conductors therein, the cable having an exposed section of metallic shielding and non-exposed section; a metallic stuffing tube with an inner cable channel and an at least partly threaded gland nut receiver space, and a constriction between the gland nut receiver space and the inner channel; a gland nut adapted to threadably engage the gland nut receiver space; and a; wherein the cable passes through the gland nut and stuffing tube with the exposed section substantially wrapped in the elongated flexible composite gasket member the gland nut above the elongated flexible composite material and the constriction below. The flexible gasket member is in electrical communication with the cable and the stuffing tube. ## Claims ### Claim 1 A stuffing tube assembly for use with a deck or bulkhead (collectively “metallic shell”) of a ship, the stuffing tube comprising: a cable having insulation on a surface thereof, a metallic shielding jacket, and conductors therein, the cable having an exposed section of metallic shielding and non-exposed section; a metallic stuffing tube with an inner cable channel and an at least partly threaded gland nut receiver space, and a constriction between the gland nut receiver space and the inner channel; a gland nut adapted to threadably engage the gland nut receiver space; and an elongated, flexible composite gasket member comprising a conductive member at least partly impregnated with a soft, tacky gel; wherein the cable passes through the gland nut and stuffing tube with the exposed section substantially wrapped in the elongated flexible composite gasket member the gland nut above the elongated flexible composite material and the constriction below. ### Claim 2 (depends on 1) The stuffing tube assembly of claim 1 wherein said conductive member is a knitted wire mesh rope. ### Claim 3 (depends on 1) The stuffing tube assembly of claim 1 wherein said gel is made from pre-cured polyurethane. ### Claim 4 (depends on 2) The stuffing tube assembly of claim 2 wherein said gel is made from pre-cured polyurethane. ### Claim 5 (depends on 1) The stuffing tube assembly of claim 1 wherein said gasket member is wrapped about said exposed section of said cable metallic shielding jacket. ### Claim 6 (depends on 5) The stuffing tube assembly of claim 5 wherein the position of said exposed section of said cable is determined by placing a marker on said cable indicating the correct position and making cuts in said cable insulation to expose said conductors in said cable. ### Claim 7 A gasket member for use in a stuffing tube assembly of a ship said stuffing tube assembly having a cable passing through it, the gasket member comprising: a wire mesh rope at least partly impregnated with a soft, tacky gel; wherein said gasket member is elongated and flexible; and wherein said mesh rope is conductive. ### Claim 8 (depends on 7) The gasket member of claim 7, further comprising: said gasket member is wrapped around said cable passing through said stuffing tube; said gasket member in electrical communication with said cable and said stuffing tube; and wherein said gasket member provides an electrical ground between said cable and said stuffing tube. ### Claim 9 (depends on 7) The gasket member of claim 7 wherein said gel is made from polyurethane. ### Claim 10 (depends on 7) The gasket member of claim 7 wherein said cable having wherein said gasket member provides a shield against EMI or an electromagnetic pulse or other electronic interference. ### Claim 11 (depends on 7) The gasket member of claim 7, further comprising: said cable having insulation on a surface thereof, a metallic shielding jacket, and conductors therein, said cable having an exposed section of metallic shielding jacket; said gasket member is wrapped about said exposed section of said cable metallic shielding jacket; and said wire mesh rope urged against said exposed section of said cable metallic shielding jacket. ### Claim 12 (depends on 7) The gasket member of claim 7 wherein said cable having wherein said gasket member provides a shield against EMI or an electromagnetic pulse or other electronic interference. ### Claim 13 (depends on 7) The gasket member of claim 7 wherein said gel is made from polyurethane.
