Heat-shrink tubing is primarily used to protect wires, connections, and cables from mechanical damage. When heated, it conforms to the surface of the applied component and helps create a neat termination for electrical installations.
For the correct selection, it is necessary to verify the diameter before and after shrinking, the shrink ratio, length, color, material, possible presence of adhesive, and the required shrinking temperature. These details are not specified in the provided materials.
