600 Pcs Heat Shrink Tubing Kit - 4:1 Ratio Adhesive Lined, Wire Shrink Wrap Tubing, Marine Grade Industrial Heat-Shrink Tubing, 7 Sizes 5 Colors

4:1 Shrink Ratio & Fast Contraction: Shrinks to 1/4 of its original diameter, delivering 30% better sealing tightness than standard options. Solves the common issue of 2:1/3:1 heat shrink tubing failing to shrink sufficiently. With a shrink temperature range of 80-125°C, heat shrink tubing forms professional-grade connections in just seconds—ideal for projects needing quick, reliable insulation.

Thicker Adhesive Coating: Inside the 4:1 heat shrink tubing kit, the adhesive layer is thicker than that of 3:1 alternatives. When heated, heat shrink tube releases more adhesive to fully seal joints, creating a waterproof, long-lasting insulation barrier. This design ensures protection against moisture, making heat shrink tubing a trustworthy choice for critical wiring tasks.

Dual-Wall Construction: Heat shrink wrap outer wall offers exceptional abrasion resistance, shielding wires from scratches and wear. The inner wall forms a consistent waterproof seal while providing excellent strain relief to prevent wire breakage from pulling. This heavy-duty dual-wall design makes the wire shrink wrap tubing perfect for all wire insulation needs, even in high-use scenarios.

600PCS-7 Sizes-5 Colors: Eventronic Wire Shrink Wrap Tubing is available in 7 different diameters of the world's most commonly used shrink tubing, ranging from 3/32“ to 3/4”.
