3:1 Heat Shrink Tubing

3:1 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. Our 3:1 adhesive-lined heat shrink tubing is packaged into a convenient cardboard reel, and we provide recommended heat shrink guns to shrink the tubing. We provide bulk discounts on larger orders, meaning the more you buy, the more you save.
