A heat shrink tubing set consisting of 127 pieces of tubing in various lengths and diameters. Heat shrink tubing is a shrinkable plastic tube used to insulate wires, providing abrasion resistance and environmental protection for stranded and solid wire conductors, connections, joints and terminals in electrical work. Heat shrink tubing can help ensure the continued performance of wiring and cables. Insulation of electrical wires and cables is first and foremost required to prevent electrical shock. However, the insulation of wires and cables also prevents the loss and dissipation of energy being conducted through the wiring.
