Deutsch DT 3-Pin Waterproof Connector – DT06-3S (Female) / DT04-3P (Male) Heavy-Duty Sealed Plug
Direct OEM-specification replacement for the Deutsch DT series 3-pin waterproof connector — the industry-standard heavy-duty sealed connector for trucks, agricultural equipment, construction machinery, and motorsport wiring harnesses. Cross-references Deutsch part numbers DT06-3S (female / socket housing) and DT04-3P (male / plug housing). Uses the 1.6mm contact series (Deutsch Size 16 contacts) in black nylon housing with individual wire seals and a secondary lock — providing IP67-rated waterproof sealing for the most demanding underbonnet and underbody applications.
The Deutsch DT series is the benchmark for heavy-duty waterproof connectors. Unlike standard automotive connectors that rely on a single housing seal, the DT series uses individual wire seals on each terminal cavity, a wedge lock (secondary lock) to prevent terminal back-out, and a silicone face seal between the mated connector halves. This triple-sealing system provides IP67 waterproof protection — suitable for continuous immersion in water up to 1 metre depth. The DT series is rated for -55°C to +125°C operating temperature and is used in the most demanding environments: mining, agriculture, marine, motorsport, and military applications.
