ABSTRACT:
A sealing member for effecting a gas-tight closure about a cable at an inlet to a hollow cable sleeve fitting. The member is annular in form and is divided on a plane parallel to the cable axis for assembly about the cable after boring a selected passage for the cable through the member. The sealing member has a plurality of radially- and circumferentially-continuous, radially outwardly-extending, longitudinally-spaced ribs engageable via a coating of plastic potting compound with an inner surface of the inlet fitting. The ribs are held in spaced relation by an integral reinforcement member which is spaced radially inwardly of the outer circumference of the ribs. A center portion of the reinforcement member is apertured so that selective boring through of the member to form a cable passage will leave internal radial ribs for bearing against the cable via a second plastic potting compound. Any number and size of cable passages may be provided for.
