Adiwo Heat Shrink Tubing, 3:1 Black Heat Shrink Tube, Dia 30mm *1.5m Long Shrinkable Tube Cable Sleeve, Waterproof Heat Shrinkable Tube For Cable Insulation, Marking, Cable Bundling, Repair

• 【Shrinkage ratio 3:1】: Wire heat shrinkable tube is designed with heat shrinkage technology and shrinks with a shrinkage ratio of 3:1. By heating, the black pipe shrinks to 1/4 of its original diameter, making the cable less likely to break and deform.
• 【Heat shrinkable tube】:Outer layer: polyethylene material, insulating and anti-wear, inner layer: hot melt adhesive, which plays the role of sealing, protection and buffering. Internal adhesive ensures a secure connection and protects against moisture and other environmental influences.
• 【Easy to use】: Heat shrinkable tube is easy to use and shrinks quickly. Just put the heat shrinkable tube on the bare wire part and heat it with a lighter or heat gun.
• 【Practical】: Covers all wire specifications needed in various applications. Mainly used for cable connection of line segments and wire harnesses, welding joints, protection and insulation of electronic components.
• 【Wide Applications】: Black heat shrink tubing has good electrical insulation, corrosion resistance, and high temperature resistance. It is an insulating protection for the exposed parts of wire connections. It is very suitable for various applications, including automobiles, electronics, household appliances, etc.
