Product Details

Non-Insulated Butt Connectors are precision-engineered from seamless T2 pure copper tube, delivering superior electrical conductivity, exceptional mechanical strength, and consistent crimping performance for secure, long-lasting wire-to-wire splicing. Designed for professional electrical installations, these bare copper butt connectors support wire sizes from AWG 22 to 1/0, making them ideal for a wide range of industrial, commercial, automotive, and marine applications.

✨ Key Design Advantages

Seamless T2 Pure Copper Construction: The seamless copper tube eliminates potential weak points from welded seams, ensuring uniform wall thickness, maximum pull-out resistance, and optimal current-carrying capacity. This design guarantees stable electrical performance and long-term durability even under high-load conditions.
Built-In Wire Stop (Notched Entry): The precision-machined wire stop (internal notched structure) prevents over-insertion of wires, ensuring consistent, correct crimp depth every time. This eliminates installation errors, simplifies assembly, and ensures reliable contact between conductors.
Thickened Tin-Plated Coating: The standard tin-plated finish features a thickened, uniform coating that provides excellent resistance to oxidation, corrosion, and environmental damage. This ensures long-term connection stability and reliable performance in general electrical wiring, automotive harnesses, and industrial control systems.

By crimping a non-insulated butt connector onto stripped conductors, all wire strands are compacted into a solid, uniform structure, preventing strand separation and improving mechanical stability. The bare copper design also allows for visual inspection of the crimp, ensuring proper installation every time, while the seamless construction delivers consistent contact pressure for safer, more reliable electrical connections.

Thanks to their precision manufacturing and standard dimensions, these non-insulated butt connectors are fully compatible with standard crimping tools, making them suitable for a wide range of conductor sizes and electrical installations across Europe, North America, and other global markets.
