Tubo termorretráctil DeLOCK 19969 4:1 con adhesivo negro 5 m x 16 mm

The DeLOCK heat shrink tube 19969 is designed to insulate and protect cables, wires and electrical connections. It is made of polyolefin, comes in black, and has a shrink ratio of 4:1. The inner adhesive bonds to cables after shrinking, creating a sealed, mechanically protected coating. The product is supplied on a practical dispenser box that keeps the tube clean and allows easy unrolling and individual cutting.

Advantages

The polyolefin construction provides durable electrical insulation while the 4:1 shrink ratio enables use on a range of cable diameters. The inner adhesive ensures a secure, moisture-resistant seal after heat shrinkage. The dispenser box protects the tube from dirt and simplifies transport, storage and cutting.

Suitable for

• Insulating and protecting cable splices and wire joints
• Repairing damaged cable insulation
• Mechanical and moisture protection of electrical connections in workshops and industrial settings
• Organising and bundling wire looms

How to use

Cut a suitable length from the dispenser, slide the heat shrink tube over the cable or joint, and apply heat evenly using a heat gun, hot air tool or suitable heat source until the tube contracts and the inner adhesive flows to form a tight seal. Allow the sleeve to cool so the adhesive cures and the polyolefin sets. Ensure adequate ventilation and follow safety instructions for the heat source used.

Recommendations

For best results, select a tube diameter that leaves a small clearance over the component before shrinking so the 4:1 ratio provides a secure fit. Apply heat evenly and avoid local overheating to prevent damage to cables or insulation. Store the dispenser box in a dry, dust-free place.
