Set termoskupljajućih cijevi DeLOCK 20867

The Heat shrink tube DeLOCK 20867 set contains 100 transparent heat shrink tubes with a 4:1 shrinkage ratio, including both single-wall and dual-wall (with internal adhesive) types. Made of polyethylene, the tubes protect and insulate cables, wires and electrical tubing by shrinking tightly around them when heated, providing resistance against weather and mechanical damage. The set is supplied in a practical storage box for tidy storage and easy access.

Advantages

This assortment offers a variety of diameters and both single-wall and adhesive-lined dual-wall options for versatile use. The 4:1 shrinkage ratio allows the tubes to reduce to approximately a quarter of their original diameter, ensuring a secure fit. Transparent polyethylene material permits visual inspection of joints and conductors while the inner adhesive of the dual-wall tubes provides a reliable seal against moisture and contaminants. The included reusable storage box protects the tubes from dirt and keeps small parts organized.

Suitable for

• Electrical cable insulation and repair
• Protecting wire joints from moisture and corrosion
• Workshop, home DIY and light industrial applications
• Colorless visual inspection and identification of connections

How to use

Select a correctly sized heat shrink tube so that it overlaps the area to be insulated. Slide the tube over the cable, splice or connector. Apply heat evenly with a hot air gun or other suitable heat source until the tube shrinks and the adhesive (for dual-wall tubes) flows to form a seal. Allow the tube to cool and verify the tube has contracted uniformly and adhered to the underlying surface.

Recommendations

For best results, use a regulated hot air gun at appropriate temperature settings for polyethylene shrink tubing. Avoid open flames and excessive heat that could deform the cable insulation or the tube. For moisture-sensitive applications choose the dual-wall adhesive-lined tubes to ensure a watertight seal. Store the tubes in the provided box in a dry place away from direct sunlight.
