Abstract: A system for protecting exposed portions of an electric cable mounted in an electrical connector from detrimental components, such as liquids and gases, by inserting a movable sealing material into a cavity in the electrical connector and displacing the movable sealing material during the insertion of the electrical cable into the electrical connector so as to form an effective seal between the outer surface of the electrical cable and the inner surface of the electrical connector to prevent any detrimental components from entering into the electrical connector and attaching a continuous glob of movable sealing material to close an opening in the electrical connector so that, when an electrical cable is mounted in the electrical connector with the bared end portion passing through the glob of movable sealing material, exposed portions of the electrical cable will be protected by the movable sealing material.
