Abstract: A connector for passing continuous insulated electrical conductors such as pins or multi-stranded wire through a surface or bulkhead, while preventing leakage of liquids and gases along the conductors, especially between gaps in the strands. An exemplary connector comprises a body having seal-zone openings in which a sealant is applied and cured around a compressed bared section of multi-stranded wire. The body contains strain relief members adjacent to the sealed openings to provide longitudinal as well as transverse strain relief. A sealant member and radially spaced clasps are located around the sealed openings and strain relief members so that the connector may be removably twist-locked onto a bulkhead without disturbing the sealed wires. A method is defined for achieving the sealed pass-through of electrical conductors.
