Heat-shrink tubing DeLOCK 20673

This DeLOCK 20673 heat-shrink tubing set is made of durable polyethylene and is designed to insulate and protect cables, wires and electrical tubes. The sleeves shrink when heated, forming a tight cover that protects against weather effects and mechanical damage. The set includes tubes in different diameters, lengths, colors and shrink ratios and is supplied in a practical storage box for tidy storage and reuse.

Advantages

The set offers a choice of four diameters, two lengths, two colors (black and red) and two shrink ratios (2:1 and 4:1), allowing flexible use for different cable sizes. Polyethylene material provides reliable electrical insulation and mechanical protection. The included reusable box keeps tubes clean and makes organization convenient.

Suitable for

• Electrical insulation and protection of wires and cable joints
• Repairing damaged cable sheaths in workshops or at home
• Color-coding and bundling of wires for installations
• Industrial cable protection and strain relief applications

How to use

Slide the appropriate tube over the cable or joint. Apply heat evenly using a hot air gun or other suitable heat source until the tubing shrinks tightly around the conductor. For tubes with 2:1 shrinkage the diameter reduces to approximately half; for 4:1 tubing the diameter reduces to approximately one quarter. Allow the tubing to cool before handling.

Recommendations

Use a controlled heat source such as a hot air gun and avoid direct flame. Select a shrink ratio and diameter that provide sufficient overlap and a snug fit after shrinking. Keep the storage box closed to protect unused tubes from dust and moisture.
