A gland which is installed in the hole of a wall between two different atmospheres to prevent the leakage of a fluid from the one side to the other side of the wall along the outer sheath of an electric cable has a tubular metallic housing which is sealingly installed in the hole and into which the cable extends. The interior of the housing is filled with a hardened filler material which completely surrounds bare portions of conductors. Beads are formed on such bare portions. Sleeves are shrunk onto the bare portions of the conductors between the respective beads and insulators for the conductors. A tension reducing clamp surrounds the outer sheath of the cable in the housing. The aperture at one end of the housing contains an O-ring which is biased against the external surface of the outer sheath of the cable and against the surface surrounding the aperture by a second ring. The conductors are further surrounded by additional insulators which extend from the filler material by way of an open end of the housing. The beads are welded or soldered onto the bare conductors between the respective pairs of insulators.

A gland for sealing a hole which is provided in a wall separating two different atmospheres and serves to allow for the passage of at least one electrical conductor, comprising a hollow housing sealingly secured to and extending through the hole of the wall, said housing having an aperture at one side of the wall and the one conductor extending through said housing and outwardly by way of said aperture; a sheath partially surrounding the one conductor in said housing so that a portion of the one conductor in the housing remains bare; a bead provided on the bare portion of the one conductor in said housing; a sleeve shrunk onto the one conductor between said bead and said sheath so that said sleeve sealingly engages the sheath; an elastomeric sealing element sealingly installed in said aperture and sealingly surrounding the one conductor in the aperture; and a mass of hardened filler material filling the interior of said housing so that said bead, the bare portion of the one conductor and said sheath are embedded in the filler material.
