What is this?
4:1 Heat shrink tubing is a type of heat shrink material that can be used for insulation protection of electrical wires and cables. Industrial heat shrink tubing can be used for the protection and insulation of mechanical equipment components, improving their service life. Shrinkable wiring wrap is commonly used for insulation and protection of automotive wire harnesses, ensuring stable operation of electrical systems.

What will I get?
Wire Heat Shrink Tubing, is in size of:
Inner diameter before shrinkage: 3/16 inch/4mm; Length: 4ft/1.22 meters

Are there any advantages of the product?
1. 4:1 dual wall marine adhesive lined, 4:1 shrinkage ratio and glue can achieve a tight and neat connection with the cable, which can effectively achieve a sealing effect. The inner layer of hot melt adhesive melts after heating, filling the gap to ensure the sealing effect;
2. Soft and durable, the heat shrink tube can be cut and folded at will, and the length of the heat shrink tube can be adjusted as needed;
3. The heat shrink tube wall has a certain thickness, which can effectively protect the cable and play a buffering and protective role.

How to use it?
1. Select the appropriate diameter and length of double-wall adhesive heat shrink tubing according to actual needs; 2. Pre-slip the double-wall adhesive heat shrink tubing on the protected wire harness or object; 3. Use a heating tool to heat the double-wall adhesive heat shrink tubing; 4. After heating, check whether the heat shrink tubing is completely shrunk and tightly fitted.

What should I notice?
Choose the right tube diameter: Too large or too small a diameter will affect the sealing effect and aesthetics of the heat shrink tubing.
