Heat Shrink Tube Cabletech 6.5 mm × 1 m, black

Cabletech heat shrink tube, 6.5 mm diameter and 1 m length in black, is a flexible thermoplastic sleeve designed to contract uniformly when heated to provide a protective, insulating cover for wires, cable joints and connectors. The tube creates mechanical support and strain relief while improving resistance to abrasion and environmental exposure. It is suitable for general electrical insulation and cable management tasks where a neat, durable finish is required.

Advantages

The heat shrink tube offers consistent shrinkage for a tight fit around irregular shapes and splices, ensuring secure insulation and reducing the risk of short circuits. Its flexible material conforms to connectors and wiring while providing mechanical reinforcement and protection against abrasion and moisture. The black colour provides a discreet, professional appearance and helps conceal markings or repairs.

Suitable for (tasks / use cases)

• Insulating individual wires and multi-core cable joints
• Providing strain relief on connector terminations
• Protecting soldered joints and splices from corrosion and abrasion
• Cable bundling and neat cable management in installations
• Repairing damaged insulation on household and automotive wiring

Key specifications

• Material: thermoplastic heat-shrinkable tubing
• Nominal expanded inner diameter: 6.5 mm
• Length: 1 m
• Colour: black
• Shrink ratio: typical for general-purpose tubing (designed to contract for a tighter fit)
• Primary functions: electrical insulation, strain relief, abrasion and moisture protection

How to use

Select a tube segment slightly longer than the area to be covered. Slide the heat shrink tube over the wire, splice or connector before making the connection when possible; for repairs, position the tube over the joint. Apply heat evenly using a heat gun, hot air tool or suitable heat source, maintaining a safe distance to avoid scorching. Heat until the tube uniformly contracts and conforms tightly to the underlying surface, then allow it to cool and set. Verify that the tube has fully shrunk and provides secure insulation and strain relief.

Usage recommendations

For best results, use a controlled heat source such as a hot air gun and apply heat evenly. Avoid open flames to prevent damage to the tubing or surrounding components. Choose a tube diameter that provides adequate overlap before shrinking and ensure proper ventilation when heating in confined spaces.
