Why Choose Our Heat Shrink Tubing?
1. Reduces to 1/4 of Its Original Diameter: Seals extremely tightly and solves the problem of many 3:1 and 2:1 shrink tubes that simply do not shrink enough.
2. Shrink Temperature: 176°F to 275°F, achieving professional connections within seconds.
3. Automatic Adhesive Release: When the adhesive shrink tubing is heated, it automatically releases adhesive that seals the connection very reliably, creating a waterproof and durable insulation.
4. High-Quality Materials: Our shrink tubing for wires is made from premium materials and contains no harmful substances such as PBBE, PBBO, or PBB.
5. Reliable Protection and Insulation: Our heat shrink tubing kit offers excellent resistance to abrasion, fire, flexibility, acids, bases, and oxidation. The outer wall provides high abrasion resistance, while the inner wall ensures a waterproof seal and excellent strain relief.
6. Various Diameters: We have included the 5 most commonly used diameters from approximately 0.24 inches to 0.79 inches. A set contains 100 pieces with selectable inner diameters: 0.24 inch (35 pieces), 0.31 inch (30 pieces), 0.47 inch (20 pieces), 0.63 inch (10 pieces), 0.79 inch (5 pieces). The length is 3.54 inches.
7. Wide Range of Applications: The waterproof heat shrink tubing can be used in marine and vehicle wiring, model making, and DIY electrical wiring. Applications include electrical insulation, environmental seals to protect against moisture, UV radiation, fuel, and chemicals, and protection of surfaces against abrasion, peeling, and bulging.

How to Use?
1. Choose the right size heat shrink tubing, whose diameter should not be more than 3 times the size of the wires, as it is a 4:1 shrink ratio.
2. Cut the shrink tube to the required length.
