3/4" Heat Shrink Tubing-3:1 Ratio Adhesive Lined-Marine Grade Heat Shrink Tube-Wire Waterproof Industrial Large Heat Shrink Tubing-Black-13.2FT

3:1 SHRINK RATIO and FAST CONTRACTION SPEED : Shrinks to 1/3 of its original diameter and seals extremely tightly, solving the problem of many 2:1 shrink tubes that don't shrink enough and therefore don't seal tightly enough.

ADHESIVE INSIDE : When the heat shrink tubing is heated, it automatically releases adhesive and seals the connection extremely reliably. This creates a 360° waterproof and durable insulation, keeping your connection safe from external elements such as water and dust.

DUAL WALL TUBING : The outer wall of the heat shrink tubing provides enhanced protection from wear and tear. The inner wall creates a consistently waterproof seal and excellent strain relief. Industrial marine grade tubing is resistant to fluids, heat, and mechanical stretch.

EASY TO USE and 6 SIZES : Simply slide heat shrink tube over your connection point and apply heat. Make professional insulated connections in seconds. (Shrink temperature: 80 to 125°C). You can conveniently cut the heat shrink tubing rolls to any length you want, and the 6 heat shrink tubing diameters can be applied to different projects.

VERSATILE APPLICATIONS : The waterproof Eventronic heat shrink tubing can be used in marine and automotive wiring, model building, and DIY electrical wiring projects. The application areas are very diverse, such as electrical insulation/environmental sealing to protect against moisture, fuel and chemicals/protection of surfaces against abrasion, peeling and denting.
