Tubo termorretráctil DeLOCK 19921

The DeLOCK 19921 heat shrink tube is made of polyolefin and designed to provide reliable insulation and mechanical protection for wires, cables and electrical tubing. When heated, the sleeve contracts to form a tight, protective layer that resists moisture and many chemicals, suitable for indoor and outdoor applications. The product comes in a dispenser box for clean, orderly storage and easy cutting.

Advantages

The polyolefin construction offers good electrical insulation and chemical resistance while the black colour gives a professional appearance. The heat shrink action ensures a snug fit around irregular shapes and joints, improving mechanical protection and strain relief. The practical dispenser box keeps the tubing free from dirt and enables controlled unrolling and individual cuts.

Suitable for

• Insulating and protecting electrical wires and cable joints
• Sealing and protecting cables from moisture and contaminants
• Workshop, industrial and general maintenance applications

How to use

Cut the required length from the dispenser box, slide the tube over the cable or joint and apply heat evenly with a heat gun or other suitable heat source until the tube shrinks tightly around the object. Allow the tubing to cool so it forms a stable, protective layer. Avoid direct flame contact and over-heating to prevent damage to the tubing or the cable beneath.

Recommendations

For best results use a calibrated heat gun at an appropriate distance and move evenly along the tubing. Select a tube diameter that provides adequate shrink ratio for a tight fit after heating. Store the dispenser box in a dry place to keep the tubing free from dust and moisture.
