Clear heat shrink with adhesive is a dual wall polyolefin heat shrink with a see through outer wall useful for visual inspection of your electrical connections. The heat shrink is lined with a heat activated adhesive that flows when heat is applied, creating a transparent and permanent water tight seal from the elements. Dual wall material is an excellent insulator and provides superior protection from abrasion. With a shrink ratio of 3 to 1, the heat shrink can be used to cover a variety of cable sizes. The operating temperature of the shrink tubing is -49°F to 257°F (-45°C to 125°C). The tubing can be shrunk using a standard heat gun or heat torch.
