Deutsch Connectors

Deutsch connectors are the industry benchmark for sealed electrical connections in automotive, marine, agricultural and 4WD applications, and this collection at 4wdstore.au brings the popular DT series together with the crimp tools and contacts needed to wire it up properly. Trusted for their environmental sealing, vibration resistance and rugged thermoplastic housings, Deutsch DT plugs are the go-to choice whenever a connection has to survive water, dust, heat and constant movement. From driving light harnesses and dual battery systems to trailers, winches, marine rigs and workshop repairs, the Deutsch range gives Australian installers a reliable, weatherproof way to join and separate wiring.

The Deutsch DT Series Explained

The DT series is the workhorse of the Deutsch line, built around a sealed connector body with a secondary locking wedge that keeps contacts firmly in place. This collection covers the common pin counts installers reach for most, including 2 way, 3 way, 4 way, 6 way, 8 way and 12 way configurations, in matched male and female pairs. Every connector is waterproof and designed for auto and marine use, making them ideal for extending circuits, adding accessories or building removable sections into a harness. Because the DT footprint is a recognised standard, plugs mate consistently across kits, so a 2 pin plug wired today will match another DT06 or DT04 housing added down the track.

Connector Kits and Assortments

For anyone who wires vehicles regularly, the bulk assortment kits are the smart way to buy. The range includes large sets from 117 pieces and 188 pieces right up to 550, 600, 1000, 1100 and 1700 piece kits, many supplied with a genuine Deutsch crimp tool. A mixed assortment such as the 188 piece set spans 2, 3, 4, 6, 8 and 12 pin connectors with multiple pairs of each, so you can tackle almost any job without running short of a particular size. Larger kits keep a workshop, four wheel drive club or serious DIY builder stocked with plugs, wedge locks and contacts in one purchase, while dedicated single-size kits such as the DT 4 way and DT 12 way plug sets are perfect for a specific project.

Crimp Tools and Contacts

A quality connection starts with the right crimp, and this collection carries the tools and terminals to do it correctly. You will find genuine Deutsch crimp tools bundled into the larger kits, along with standalone closed barrel crimpers such as the iCrimp DT12 and DT20, which use a 4 way indent and 8 impression jaw to form a clean, gas-tight crimp on Deutsch contacts. Solid stamped and machined contacts are available separately too, including size 16 male and female pins sold in packs and pre-terminated options, plus part-specific contacts and connectors with pre-attached wires for quick assembly. Matching your contacts to your wire gauge, typically in the 14 to 16 AWG range for DT, is the key to a secure, low-resistance join.

Choosing the Right Deutsch Setup

Selecting the right combination comes down to how many circuits you are joining, the wire size you are running, and whether you already own a crimp tool. Count the wires per connector to pick the pin count, confirm your contact style and wire gauge, and decide between a single-size plug kit for one job or a large assortment for ongoing work. The quick picks below make it easy to head in the right direction.

• Wiring a simple two-wire accessory or trailer feed: choose a DT 2 way or 4 way waterproof plug kit.
• Building multi-circuit harnesses: step up to 6 way, 8 way or 12 way DT connectors.
• Fitting out a workshop or club: pick a 550 to 1700 piece kit supplied with a genuine Deutsch crimp tool.
• Need tools or spares only: add an iCrimp DT12 or DT20 crimper and size 16 solid contacts to suit your gauge.
