Heat shrink tubing kit with a shrinkage ratio of 3:1, including adhesive, marine-grade heat shrink film and industrial-grade heat shrink tubing.

3:1 Shrink Ratio: Shrinks to 1/3 of its original diameter, forming a watertight seal. Solves the problem of insufficient shrinkage with 2:1 shrink ratio heat shrink tubing. Built-in Adhesive: Upon heating, the adhesive seeps out and seals the joint, forming a durable, waterproof insulation layer. Multiple Sizes: We offer 7 of the most commonly used diameters, from 3/32 inch to 3/4 inch. The heat shrink tubing is pre-cut to 3.5 inches. Easy to Use: Simply slip the heat shrink tubing over the connection point and heat. Professional-grade connection in seconds. Double Wall: The outer wall provides abrasion resistance. The inner wall forms a watertight seal and relieves stress. Shrink Ratio: 3:1 Operating Temperature: -55°C to +125°C Minimum Shrink Temperature: 70°C Full Shrink Temperature: 110°C Maximum Dielectric Strength: 15 kV/mm Flame Retardant: Yes. Upon heating, this heat shrink tubing shrinks to 1/3 of its original diameter. Its high shrink ratio allows for the repair of most damaged cable sheaths without disassembling the connector. Therefore, compared to a 2:1 shrinkage ratio, a 3:1 shrinkage ratio is suitable for a wider range of applications. Furthermore, 3:1 marine heat shrink tubing can shrink more tightly around cables and terminals, eliminating any air gaps.
