Nylon Insulated Butt Connectors, also known as butt splice connectors, are manufactured from seamless T2 pure copper tubes with an internal wire stop structure. The built-in wire stop avoids over-insertion of stripped wires, ensuring consistent crimp depth and reliable electrical contact every time.
The copper body comes with standard tin-plated coating only, offering great anti-oxidation and anti-corrosion performance while maintaining stable high conductivity for long-term wire connections.

The outer layer is made of tough nylon insulation, which features superior heat resistance, abrasion resistance and mechanical strength compared with PVC insulation. It effectively prevents short circuits, insulates wires from dust and collision damage, and stands up to higher working temperature environments.

When you crimp both ends of the connector onto stripped wire strands, the seamless copper tube tightly locks all wire strands together to prevent strand separation, loose connections or pull-out risks. The nylon insulation won’t crack or deform during standard crimp operations.
These splice connectors fit wire gauges AWG 22 to AWG 10 perfectly, widely used in automotive wiring harnesses, industrial control panels, machinery equipment and household electrical appliances. They are fully compatible with all standard manual crimp tools for fast, simple on-site installation.
