Heat Shrink Tubing

Heat shrink tubing from Hoffman Products includes both 2:1 and dual wall 3:1 shrink ratios, meaning they can shrink down to 1/2 or 1/3 of their original diameter when heated. They are sold in reels with 100, 200, 250, and 500 foot lengths, with inner diameters ranging from 1/16" to 1". The 2:1 shrink ratio tubing is polyolefin while the 3:1 ratio heat shrink is dual wall, lined with adhesive. Heat shrink is made to protect wires and inside components. The dual wall adhesive version is especially ideal for power distribution in that it creates an environmentally tight seal. Both versions carry a VW-1 flammability rating.
