Heat Shrink Tube Kit — 800PCS PE Cross-Linked Thermoresistant Tubing | Waterproof Cable Insulation
A comprehensive 800-piece heat shrink tube kit covering multiple diameters and colours for professional wire insulation, cable repair, connector protection, and electrical connection sealing. Made from cross-linked polyethylene (PE) — the same material used in industrial and automotive wiring harnesses — these tubes shrink uniformly when heated to create a tight, waterproof, insulating sleeve around wires, solder joints, and connectors. The 2:1 shrink ratio means each tube shrinks to half its original diameter, accommodating a wide range of wire and connector sizes.

Why Cross-Linked PE for Heat Shrink?
Cross-linked polyethylene (XLPE/PE) is the preferred material for heat shrink tubing because the cross-linking process creates a polymer network that:
- Shrinks uniformly — consistent shrinkage across the full length of the tube
- Maintains shape after shrinking — does not re-expand when cooled
- Resists chemicals — compatible with oils, fuels, and common solvents
- Provides electrical insulation — high dielectric strength for wire insulation applications
- Waterproof seal — conforms tightly to the underlying surface, excluding moisture
Key Features
- ✅ 800PCS comprehensive kit — multiple diameters and colours for all common wire and connector sizes
- ✅ Cross-linked PE material — industrial-grade heat shrink, not cheap PVC
- ✅ 2:1 shrink ratio — accommodates a wide range of wire diameters in each tube size
- ✅ Waterproof after shrinking — protects solder joints and connections from moisture
- ✅ Excellent electrical insulation — prevents short circuits and electrical leakage
- ✅ Multi-colour — colour-code wiring for easy identification (red, black, blue, green, yellow, white)
- ✅ Heat gun or lighter compatible — shrinks with a heat gun, soldering iron, or lighter
How to Use Heat Shrink Tubing
- Select a tube diameter slightly larger than the wire or connector to be covered.
- Cut the tube to the required length (allow 5–10mm overlap on each side of the joint).
- Slide the tube over the wire before making the solder joint or connection.
- Make the solder joint or connection, then slide the tube over the joint.
- Apply heat evenly along the tube using a heat gun (recommended) or lighter. The tube will shrink uniformly to conform tightly to the wire.
- Allow to cool before handling.
Common Applications
- Wire solder joint insulation and protection
- Automotive wiring harness repair and protection
- Connector and terminal insulation
- Cable end protection and strain relief
- Wire colour-coding and identification
- PCB component lead insulation
- Antenna and coaxial cable protection
- DIY electronics project wire management
- Bicycle and motorcycle cable protection
Frequently Asked Questions
Q: What temperature is needed to shrink these tubes?
A: Cross-linked PE heat shrink typically begins shrinking at 70–90°C and fully shrinks at 120–150°C. A heat gun set to 150–200°C is ideal. A lighter works but requires careful, even application to avoid burning.
Q: Can I use a soldering iron to shrink the tube?
A: Hold the soldering iron close to (but not touching) the tube and move it along the length. Direct contact will melt and damage the tube. A heat gun is strongly recommended for best results.
Q: What sizes are included in the 800PCS kit?
A: The kit includes multiple diameters (typically 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm) in multiple colours. The exact size distribution is shown on the kit packaging.
