JRready ST6339 Deutsch DT 2-Pin Connector Kit - Durable DT Series

In this review the JRready ST6339 Deutsch DT Connector 2 Pin kit is evaluated for wiring harnesses and harsh-environment electrical work; the single biggest reason to buy is reliable, serviceable DT-style connections with a proper Deutsch crimp tool included. The kit bundles five 2-pin gray DT housings, size 16 stamped open-barrel contacts rated for typical 14-18 AWG wiring, sealing plugs and a removal tool, so installers get a complete set that addresses assembly, corrosion resistance and waterproofing in one purchase.

Key Features

• Complete kit with crimp tool: Includes the ACT-LY-16DT Deutsch crimp tool so users can crimp size 16 open barrel terminals correctly for secure connections.
• Size 16 stamped contacts: High-quality stamped contacts rated for about 13A provide dependable conductivity for 14-18 AWG wiring in automotive and industrial circuits.
• Rugged shell material: Reinforced glass fiber Nylon66 housings resist corrosion and survive temperature extremes from -40 to 125 C for use in motorsport and outdoor gear.
• Waterproof and dustproof: DT connectors include sealing plugs and a proven design that prevents leakage and contamination after proper assembly.
• Versatile termination: Contacts accept crimping and soldering, improving solderability and adding flexibility for different installation preferences.

Who It's For

The JRready ST6339 kit is aimed at DIY mechanics, race teams and technicians building or repairing wiring harnesses who need a handful of robust 2-pin DT connectors and a matched crimp tool. It suits anyone working on off-road, rally or marine electrical systems where moisture resistance and temperature tolerance matter most.

Those who should look elsewhere include users needing higher pin counts, specialized pin spacings or extremely high current capacity above the 13A per pin rating; also large-scale manufacturers who require bulk production tooling and higher-volume packaging.

Pros & Cons

Pros

• Complete package with ACT-LY-16DT crimper makes consistent crimps easier for home shops and pros.
• Sealed DT housings and sealing plugs deliver reliable waterproof and dustproof performance when assembled correctly.
• Sturdy Nylon66 shells and tinned copper contacts provide corrosion resistance and long-term durability in harsh conditions.

Cons

• Kit is limited to five 2-pin housings and size 16 contacts, so larger projects require multiple purchases.
• Some users may prefer gold-plated contacts for extreme low-resistance signal applications; these are tinned copper instead.
