Collection: Non-Insulated Step Down Butt Connectors
Non-insulated step down butt connectors provide a secure and reliable way to splice together two different wire sizes in automotive, marine, and industrial applications. These connectors are designed to ensure high conductivity and strong mechanical performance, especially where insulation is added later or heat shrink is applied externally. Ideal for low-voltage electrical systems, they support custom configurations and are commonly used in harness repairs, custom wiring, and fleet maintenance. The step-down design simplifies joining dissimilar AWG wires while maintaining proper contact and current flow.
