Heat shrink tube DeLOCK 20910 dual wall black 122 pieces

The DeLOCK 20910 heat shrink tube set contains 122 pieces of black dual-wall shrink tubes made of polyolefin with an inner adhesive layer and a 3:1 shrinkage ratio. The tubes provide electrical insulation and mechanical protection for cables, wires and electrical tubes; when heated they shrink to approximately one third of their original diameter and the adhesive bonds to the cable surface for a sealed finish. The set is supplied in a reusable storage box that keeps the tubes clean and organised.

Advantages

Dual-wall construction with inner adhesive ensures durable sealing and moisture resistance. The 3:1 shrink ratio allows use with a wide range of cable diameters. The set includes multiple sizes and 122 pieces for flexible, varied use. Polyolefin material provides good electrical insulation and mechanical protection. The storage box protects the contents and can be reused for small parts.

Suitable for

• Insulating and protecting electrical wires and cable joints
• Repairing damaged cable insulation
• Moisture-sealing connections in outdoor or industrial installations
• Workshop, home and industrial cable maintenance tasks

How to use

Choose a shrink tube of appropriate diameter, slide it over the cable or joint to be insulated, then apply heat evenly using a hot air gun or suitable heat source. Heat until the tube shrinks uniformly and the inner adhesive flows and bonds to the cable surface, forming a sealed covering. Allow the tube to cool before handling to ensure the adhesive sets.

Recommendations

For best results use a temperature-controlled hot air gun and maintain an even distance while heating to avoid overheating. Select a tube with a diameter that allows the required shrinkage (3:1) for a snug fit. Store the tubes in the provided box in a dry place away from direct sunlight.
