Abstract: A method and apparatus for blocking fluid and fluid vapors having a connecting member to connect a set of wires passing through bores formed in a plug body. Each wire having been cut, stripped of insulation and attached to the connecting member within the bores to create a consistent, solid barrier while maintaining the electrical integrity of the connection. The connection assembly and a portion of the insulation is then overmolded with an appropriate fluid resistant material or plastic resin which further interrupts and eliminates fluid leakage and fluid vapor migration.
