DT 4 WAY PLUG -BLACK

Deutsch DT 4-Way Plug Connector – Black Sealed Plug Housing

The Deutsch DT Series 4-way plug is a waterproof, environmentally sealed connector housing designed for demanding motorsport, off-road, and performance automotive wiring applications. Built to the proven Deutsch DT Series standard, this 4-circuit plug connector delivers reliable sealed performance in engine bays, underbody routing, and harness branch locations across race cars, rally builds, and high-performance road vehicles.

Deutsch DT Series Design

The DT Series uses a dual-lock positive retention system and secondary lock wedge to secure size 16 terminals and ensure they cannot be displaced under vibration or mechanical stress. The moulded rubber seals on each cavity provide individual wire sealing across a range of cable diameters, achieving a fully waterproof connection when mated. The black housing colour aids identification and circuit tracing in complex multi-connector harness layouts.
