An apparatus, combination and method of sealably enclosing junctions include an elastomeric seal that extends at least partially into a socket of a connector. The presently disclosed technology can be useful in sealably enclosing junctions of individual, jacketed-wire conductors to the terminals of underwater connectors. The presently disclosed technology can serve some or all of several purposes. A first of these purposes can be to sealably enclose a conductor-to-connector junction to prevent fluid ingress. A second purpose can be to electrically insulate a junction from its external environment, and a third purpose can be to provide strain relief for a jacketed-wire conductor at a junction.
