4:1 Dual Wall Heat Shrink Tubing with Glue (1 Meter)
4:1 Dual Wall Heat Shrink Tubing with Glue (1 Meter)
This 1-meter dual wall heat shrink tubing features a 4:1 shrinkage ratio and internal hot-melt adhesive to provide waterproof, insulated protection for wires and cable connections. It is designed for home appliance maintenance, wire branch protection, and equipment where a sealed, corrosion-resistant finish is required.
Key features
- 4:1 High Shrinkage Ratio – Adapts to irregular shapes and provides a tight, secure fit with a 4:1 shrinkage capability.
- Dual Wall Design – Combines an outer polyolefin layer with an inner hot-melt adhesive to seal out moisture and prevent leaks.
- Flame Retardant – Meets VW-1 standards for fire resistance to ensure safe use in electrical applications.
- Wide Temperature Range – Operates effectively in environments from -45°C to 125°C, with full shrinkage achieved at 125°C.
- Voltage Rating – Rated for up to 1000V, providing robust electrical insulation.

FAQ
How do I calculate the diameter I need?
Please note that the tubing width differs from the diameter because it is a circle. To find the correct diameter for a specific flat width, divide your required width by 1.57.
Is this tubing waterproof?
Yes, the internal hot-melt adhesive layer creates a waterproof seal upon shrinking.
What is the shrinkage temperature?
The tube begins shrinking at 80°C and reaches full shrinkage at 125°C.
