Tubo termorretrátil DeLOCK 19762 preto poliolefina

The DeLOCK 19762 heat shrink tube is made of durable black polyolefin and is designed to provide reliable insulation and mechanical protection for wires and cable joints. When heated, the tube shrinks to form a tight, weather-resistant sleeve that helps seal cable ends and prevents damage from moisture and abrasion.

Advantages

This heat shrink tube offers a secure fit and good dielectric insulation thanks to its polyolefin construction. Its black finish provides a discreet appearance while the adhesive-lined option melts when heated to create a sealed bond around the cable. The material resists mechanical wear and environmental influences, extending the service life of repaired or joined cables.

Suitable for

• Insulating and protecting electrical wire splices
• Repairing damaged cable jackets
• Sealing cable ends against moisture and dust
• Automotive wiring and general electrical maintenance

How to use

Slide the appropriate length of heat shrink tube over the cable or splice, ensuring the adhesive-coated side (if present) faces the area to be sealed. Apply even heat using a hot air gun, moving the gun back and forth to prevent scorching. As the tube shrinks, the adhesive layer will melt and flow to form a bonded seal; continue heating until the tube conforms tightly around the cable and the adhesive has flowed. Allow the assembly to cool so the adhesive solidifies and the tube sets.

Recommendations

Choose a tube diameter that provides sufficient overlap before shrinking; follow the hot air gun manufacturer's temperature guidance to avoid overheating the cable insulation. For critical installations, inspect the seal after cooling and test the electrical insulation where applicable.
