Abstract
Abstract A method of sealing a molded bushing to prevent leaking. The metal conductor area just beyond the edge of the bushing is coated with an elastomeric material. The coated area is then covered with a resinous material such as a thermosetting epoxy resin, which adheres to the bushing, the conductor, and the elastomeric material. Both the thermosetting material and the elastomeric material are then cured to provide a water-tight seal between the end of the bushing and the electrical conductor.
