The Auto-Connect HST12B is a black heat-shrink tubing with a 12 mm diameter that is ideal for neatly insulating and protecting cable connections in car audio and automotive electrical systems. This heat-shrink tubing ensures a professional finish and provides additional mechanical protection, especially for power cables, cable lugs, and other electrical connections.

When heated, the material shrinks evenly around cables and connection points. This reliably insulates exposed areas while also protecting them from dirt, moisture, and mechanical stress. With its diameter, the HST12B is particularly suitable for 20–25 mm² or 4 AWG cables and compatible connectors. The package includes 10 pieces of black heat-shrink tubing.
