Heat Shrink Tube 4mm (1 متر)

Heat Shrink Tube 4mm (1 متر) is a versatile protective sleeving designed for insulating, bundling and protecting wire joints, terminals and small components. Supplied in a 1 متر length, this 4mm diameter tube offers a compact, easy-to-install solution for electrical, electronic and general-purpose repair tasks.

Constructed from a flexible, shrinkable polymer, the tube contracts uniformly when heat is applied to form a tight, protective barrier around cables and connections. It helps reduce strain on joints, resist abrasion and provide a neat finish to harnesses and repairs. The neutral appearance makes it suitable for both professional and hobbyist applications.

Typical uses include insulating exposed conductors, protecting soldered joints, securing splices, color-coding circuits, and preventing moisture or dust ingress in low-exposure environments. The tube is compatible with common hand tools used to apply heat, such as a heat gun or other controlled heat sources, and it can be trimmed to the exact length required before installation.

When selecting tubing for a specific task, consider wire gauge, bundle diameter and the required final thickness after shrinking to ensure a proper fit. Store the product in a cool, dry place away from direct sunlight to preserve its performance. This 4mm size is particularly useful for small cables, sensor leads and delicate assemblies where a compact protective sleeve is needed.
