Tubo termorretráctil DeLOCK 20908 308 uds. multicolor

This DeLOCK set contains 308 pieces of multicolour polyolefin heat shrink tubing and solder wire connectors designed to protect and insulate cables, electrical tubes and wires. The assortment includes six diameters and two lengths of heat shrink tubes plus four sizes of solder wire connectors, all supplied in a practical storage box for clean, compact storage.

Advantages

The polyolefin heat shrink tubes offer a 2:1 shrinkage ratio that reduces the diameter to half when heated with a hot air gun, providing reliable insulation and mechanical protection. Solder wire connectors combine a solder sleeve and heat-shrink insulation to form a waterproof, strain-resistant joint after heating and cooling. The reusable storage box keeps components free of dirt and dust and can also store small tools and accessories.

Suitable for

• Electrical insulation of single wires and cable joints
• Repairing and protecting wiring in appliances, vehicles or workshop projects
• Creating waterproof, mechanically robust soldered connections
• Organizing small cable repair parts and accessories

How to use

Select the appropriate diameter of heat shrink tube or solder wire connector for the wires to be joined or insulated. For tubing, slide the tube over the cable or joint and apply heat evenly with a hot air gun until the tube shrinks to fit tightly. For solder wire connectors, insert stripped wire ends into the solder sleeve, hold in position and apply heat with a heat gun until the solder melts and the shrink tubing contracts. Allow the connection to cool so the solder solidifies and the heat-shrink forms a sealed insulation layer.

Recommendations

Use a temperature-controlled hot air gun and maintain an appropriate distance to avoid overheating. Strip wires to the correct length before inserting; ensure proper electrical contact before sealing. Store the set in the supplied box to protect components from dust and moisture.
