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. It can also be used to repair the insulation on wires or to bundle them together, or to protect wires from minor abrasion. Hi-Line has several heat shrink tubing options, including general purpose thin wall (Polyolefin), dual wall and heavy wall heat shrink tubing and more.
