An assembly having an externally threaded pipe nipple with an inserted grommet couples to a motor frame and to a conduit box, supporting the conduit box to the motor frame and providing a pathway for the motor lead through the grommet and nipple into the conduit box. The conduit box is configured to connect motor lead connections to the incoming power supply. A sealing material, such as a fluid elastomeric material, is poured into the pipe nipple and allowed to cure. The grommet abuts against a stop portion of the pipe nipple, retaining the sealing material. A nut having external threads mates with internal threads of the pipe nipple. As the nut is rotated and tightened, it compresses the sealing material against the inner surface of the pipe nipple and against the motor lead wires, and thus seals the electrical connections within the conduit box from the motor and environment.
