Truck-Lite 97159 7-Way Metal Trailer Connector Plug (7-Conductor, Rugged Die-Cast Zinc Female 7-Pole Plug)

Restore maximum power routing and heavy-duty reliability to your commercial fleet with the ultra-rugged design of the Truck-Lite 97159 7-Way Metal Trailer Connector Plug. Specifically engineered as an exact OEM replacement 7-conductor female plug for primary tractor-to-trailer auxiliary lines, this die-cast metal connector is a critical hardware solution for fleet maintenance garages, mobile service mechanics, and long-haul transport logistics.

Built to withstand punishing over-the-road operational environments where standard plastic plugs crack and fail, the 97159 features a premium heavy-duty zinc die-cast external housing. Hidden within its metal shield is a high-performance nylon insert that holds the internal connections perfectly stable. This structural nylon core is highly resistant to aggressive shop chemicals, degreasers, brake cleaners, and petroleum-based solvents—preventing early terminal shifting or melting.

To ensure uncompromised current transmission and minimal voltage drop across your stop, turn, tail, and auxiliary circuits, the plug features solid brass terminals. It features a unique 360-degree internal cable clamp that acts as an aggressive strain-relief anchor, ensuring that intense frame vibrations or sudden tugs during tight jackknife turns will not pull the cable leads out of their seats. Complete with an integrated rear moisture seal, this heavy-duty plug permanently blocks out road salt, highway mud, and driving rain to eliminate green-wire terminal corrosion.
