When you're splicing different gauge wires in your rig's electrical system, these professional-grade heat shrink step-down butt connectors get the job done right the first time. No more struggling with mismatched wire sizes or worrying about loose connections that could leave you stranded.
Built for Heavy-Duty Performance
- Pure Copper Construction: Made from 110 alloy copper with electro tin plating for maximum conductivity and corrosion resistance that stands up to road salt, moisture, and temperature extremes
- Adhesive-Lined Heat Shrink: Creates a waterproof seal that protects your connections from the elements - critical for trailer wiring and exterior lighting circuits
- Visual Inspection Window: Translucent tubing lets you verify proper wire insertion and connection quality before you crimp
Professional Installation Features
These step-down connectors handle the tricky job of joining 16-14 AWG wire to 12-10 AWG wire seamlessly. The yellow color coding makes wire identification quick and easy during troubleshooting or future maintenance. Simply strip your wires, insert into the appropriate ends, crimp with quality terminals, then apply heat to activate the adhesive seal.
Each connector delivers maximum tensile strength after crimping, ensuring your electrical connections stay solid through countless miles of road vibration. Perfect for trailer harnesses, auxiliary lighting, and any application where you need to step down wire gauge reliably.
