UNBRANDED Heat Shrink End Cap Black - 40mm

The UNBRANDED Heat Shrink End Cap Black provides a durable, permanent seal for the ends of electrical cables, wires, and harnesses. Constructed from high-quality, heat-shrinkable tubing material, it is designed to protect against environmental factors that can cause corrosion, wear, and electrical failure. A key feature is the internal hot-melt adhesive lining, which melts during the heating process to create a reliable, waterproof, and airtight seal that prevents moisture ingress and protects against oxidation, ozone, and harmful UV rays.

Ideal for a wide range of professional and DIY electrical applications, these end caps are simple to install using a standard heat gun. The tubing will begin to shrink at approximately 110°C and will be fully recovered and sealed at 130°C, forming a tight, protective barrier. This makes them perfect for terminating cable ends during installation or for sealing and protecting wires during long-term storage, ensuring connections remain secure and corrosion-free.

The product offers excellent thermal stability, with a continuous operating temperature range from -45°C to +105°C, making it suitable for use in both extreme cold and high-heat environments. The robust black colour provides additional UV protection and a professional, discreet finish that blends seamlessly with most wiring looms. With a high 3:1 shrink ratio, the tubing can accommodate a significant reduction in diameter, allowing it to form a tight seal on various cable sizes.

Available in multiple sizes, these heat shrink end caps are an essential component for any electrical toolkit, offering a simple yet highly effective solution for cable management, insulation, and long-term protection. They help to improve safety, prevent short circuits, and extend the lifespan of your electrical installations.
