MIL-DTL-24231 is the US Navy specification for pressure-proof single- and multiple-cable connectors, plugs, receptacles, adapters and hull inserts — the interconnect used where water ingress and hydrostatic pressure are the design drivers. Bodies are nickel-copper alloy for salt-water corrosion resistance, the gland nut compresses packing against the conductors, and a GRE-backed polyurethane insert blocks water migration through the connector if the cable is damaged. Typical applications: hull penetrators, deck and mast interconnect, submarine and subsea sensor runs, and dry-mate submersible power/signal junctions.
