Deutsch DT 3-Pin Waterproof Connector Housing – DT04-3P & DT06-3S, Flame-Retardant

Deutsch DT series 3-pin connector housings — sold as housing-only for harness builders who source contacts separately or who need replacement housings for existing harnesses. The DT04-3P is the male plug housing (accepts male pin contacts); the DT06-3S is the female receptacle housing (accepts female socket contacts). Glass-filled nylon (PA66-GF) construction with UL94 V-0 flame retardant rating — the housing will not sustain combustion if ignited, a critical safety requirement for automotive and vehicle wiring applications.

Housing-Only vs Complete Set — When to Order Housing Only

• Complete set (housing + contacts + wedge lock + wire seals): For new harness builds where all components are needed. Most cost-effective for new installations.
• Housing only (this product): For: (1) replacing a cracked or broken housing while reusing existing contacts; (2) harness builders who purchase contacts in bulk separately; (3) production environments where contacts are loaded by automated equipment and housings are sourced separately; (4) replacing a housing damaged by impact or chemical exposure while the contacts remain serviceable.

Frequently Asked Questions

What contacts are compatible with DT04-3P and DT06-3S housings?

All Deutsch DT series size 16 contacts are compatible: 0462-201-16141 (female socket contact, for DT06-3S) and 0460-202-16141 (male pin contact, for DT04-3P). Both tin-plated and gold-plated variants are compatible. The contacts are inserted from the rear of the housing and locked by the lancing feature — the wedge lock (W3S for 3-pin) provides secondary retention.

What is UL94 V-0 flame retardant rating?

UL94 V-0 is the highest flame retardant rating for plastic materials in the UL94 standard. A V-0 rated material: (1) self-extinguishes within 10 seconds after the ignition source is removed; (2) does not drip flaming particles; (3) does not burn through the test specimen. For automotive and vehicle wiring, V-0 rated connector housings are required by most OEM specifications to prevent fire propagation in the event of an electrical fault.

Can I replace just the housing without replacing the contacts?

Yes. Remove the wedge lock, extract the contacts using a Deutsch extraction tool, transfer the contacts to the new housing, and reinstall the wedge lock. Inspect each contact’s locking lance for deformation before re-insertion — a bent lancing lance will not seat correctly in the new housing. Replace any contacts with damaged lancing lances.

What color options are available for DT housings?

Standard DT housings are black. Deutsch also produces DT housings in gray, green, red, and yellow for color-coding different harness circuits or connector functions. Color-coded housings are useful in complex harnesses where multiple identical pin-count connectors must be distinguished — for example, using red for power circuits and black for signal circuits.

Typical Applications

• Harness repair: Replacing cracked or broken DT housings on existing vehicle harnesses
• Production assembly: Housing supply for automated harness assembly lines
• Motorsport: Custom harness builds with separately sourced contacts and housings
• Agricultural: Replacement housings for implement harness connectors damaged in the field
• Workshop stock: Replacement housing inventory for common DT connector repairs
