Heat-shrink tubing DeLOCK 20674

The DeLOCK 20674 heat-shrink tubing set provides organised protection and insulation for cables, electrical wires and tubing. The sleeve material shrinks under heat and forms a tight fit around conductors and connections, reducing exposure to weather and mechanical damage. The set includes multiple diameters, lengths and colours stored in a reusable carry case with adjustable compartments for easy transport and sorting.

Advantages

The kit contains hoses in ten diameters, four lengths and five colours, allowing selection of the correct size and colour for different wiring tasks. The included case protects the contents from dirt and damage, has a carry handle for transport and adjustable partitions to accommodate varying tube lengths. With a 2:1 shrink ratio and operating temperature range of 70–125 °C, the tubing offers reliable shrink performance for insulation and strain relief in many environments.

Suitable for

• Insulating and protecting electrical wire splices and terminations
• Repairing damaged cable jackets and providing strain relief
• Colour-coding wires and cable bundles
• Workshop, home DIY and light industrial cable organisation tasks

How to use

Select a tube with a diameter slightly larger than the cable or splice in its unshrunk state. Slide the heat-shrink tubing over the area to be insulated, then apply heat evenly (for example with a hot air gun) until the tubing contracts and forms a tight seal. Allow the tubing to cool before moving the cable. Use suitable heat settings within the specified temperature range to avoid damage to the tubing or the insulated components.

Recommendations

For reliable results, choose tubing with the correct unshrunk diameter and apply heat evenly. Use a regulated hot air gun and avoid open flames. Store remaining tubing in the supplied case to protect it from dust and mechanical damage.
