## Summary description

The DeLOCK Heat Shrink Tube Assortment Box includes 135 pieces of transparent tubes with a shrinkage ratio of 2:1 for single wall and 3:1 for dual wall with adhesive. Made from durable polyethylene, these tubes provide excellent insulation and protection for wires and connections. Ideal for various applications, they ensure a secure fit and are easy to use.

## Long description

This heat shrink tube set by Delock is designed to insulate and protect cables, electrical tubes and wires. When heat is applied the sleeve contracts and tightly encloses the cable; an inner adhesive layer on the dual-wall tubes bonds to the cable to improve moisture and mechanical protection. The tubes are transparent and made from polyethylene.
Advantages
The assortment includes multiple diameters and two shrink ratios (2:1 single-wall and 3:1 dual-wall with adhesive), allowing use on a wide range of cable sizes. A reusable plastic storage box keeps the tubes clean and organised and can also store small accessories. The materials provide reliable insulation and basic mechanical protection for electrical connections.
Suitable for
Electrical wiring repair and insulation
Protection of cable joints and soldered connections
Workshop, home and industrial cable maintenance
Colourless identification when transparency is required
Key specifications
Brand: DELOCK
MPN: 20866
EAN: 4043619208661
Material: Polyethylene
Product colour: Transparent
Total pieces: 135
Shrink ratio 2:1, single-wall: 40 × Ø 3.0 mm; 25 × Ø 5.0 mm; 30 × Ø 10.0 mm; length ≈ 98 mm each
Shrink ratio 3:1, dual-wall with inner adhesive: 25 × Ø 3.2 mm; 10 × Ø 6.4 mm; 5 × Ø 12.7 mm; length ≈ 98 mm each
How to use
Cut the required tube to length, slide it over the cable or joint and apply heat with a hot air gun or equivalent heat source. For 2:1 tubes expect the diameter to reduce to approximately half of the original size; for 3:1 adhesive-lined tubes expect shrinkage to about one third of the original diameter. Ensure even heating and maintain a suitable distance to avoid overheating the cable insulation.
Usage recommendations
Use a regulated hot air gun for consistent results; allow adhesive-lined tubes to cool before handling to ensure a secure bond. Select a tube diameter that, after shrinking, will fit snugly around the cable or connection.
