Inserting a stranded aluminum cable into the annular insert portion and crimping the connector body, the insert portion and the cable, causes the outer strands of the stranded aluminum cable to be extruded through the plurality of apertures, removing oxide film on the exterior surface of the aluminum cable and forming a sealed electrical connection between the aluminum cable and the copper connector body.
