Θερμοσυστελλόμενο μακαρόνι DeLOCK 19970 5 m x 20 mm μαύρο με κόλλα

The DeLOCK heat shrink tube 19970 is a 5 m long, 20 mm diameter black polyolefin sleeve with inner adhesive and a 4:1 shrink ratio. When heated, the sleeve contracts to form a tight, adhesive-sealed layer around cables, wires or tubing, providing mechanical protection and environmental sealing suitable for workshop and industrial use. The product is supplied in a practical dispenser box for tidy storage and easy cutting.

Advantages

The adhesive-lined polyolefin material ensures a secure bond to the cable after shrinking, improving moisture resistance and long-term insulation. The 4:1 shrink ratio allows coverage of fittings and connectors of varying diameters. The dispenser box protects the tube from dirt and enables controlled unrolling and individual cutting during installation.

Suitable for

• Insulating electrical connections and splices
• Protecting cables and wiring from mechanical damage
• Sealing joints against moisture and dust in workshops or industrial environments
• Repairing damaged cable sheaths

How to use

Measure and cut the required length from the dispenser box. Slide the heat shrink tube over the cable, joint or connector so it fully covers the area to be insulated. Apply heat evenly with a heat gun or other controlled heat source until the tube uniformly shrinks and the inner adhesive flows to form a seal. Allow the sleeve to cool before handling.

Recommendations

Use a regulated heat gun and keep a safe distance to avoid overheating. Ensure surfaces are clean and dry before application for optimal adhesion. For electrical work, disconnect power and follow applicable safety standards.
