Heat shrink tubing set Cabletech — 170 pcs, 10 cm black tubes, 6 diameters

Cabletech heat shrink tubing set contains 170 black tubes, each 10 cm long, supplied in six different diameters to cover a range of wiring and cable diameters. The kit is intended to provide electrical insulation, mechanical protection and neat bundling of wires, splices, terminals and connectors. Tubing material shrinks when heated to form a tight, durable sleeve around joints and exposed conductors, improving strain relief and preventing short circuits.

Advantages

The set offers a comprehensive assortment of tube diameters in a single kit, eliminating the need to buy individual sizes. Consistent 10 cm length across all pieces simplifies planning and cutting. Black color provides a neutral, low-visibility finish for professional-looking repairs and cable management. Heat shrink material delivers reliable insulation, abrasion resistance and improved mechanical support for cable joints and soldered connections.

Suitable for

• Electrical repair and insulation of wire splices
• DIY electronics projects and prototype wiring
• Automotive wiring protection and harness repairs
• Cable management and bundling in home or office installations
• Protecting terminals, connectors and solder joints from corrosion and abrasion

Key specifications

• Total pieces: 170 tubes
• Tube length: 10 cm (each piece)
• Color: black
• Number of diameters: 6 different sizes
• Material: heat-shrinkable polymer (provides electrical insulation and mechanical protection)

How to use

Slide an appropriately sized tube over the wire or joint before making the final connection. After completing the splice, position the tube to fully cover the exposed area and apply heat evenly using a heat gun, lighter or soldering iron with a heat-shrink attachment until the tube contracts and conforms to the underlying shape. Allow the sleeve to cool to ensure a secure, tight fit. Trim excess length with scissors or wire cutters if needed.

Usage recommendations

Choose a tube diameter slightly larger than the unshrunk cable or connector, so it can be positioned easily prior to heating. Apply heat progressively and keep the heat source moving to avoid overheating or burning the tubing. For automotive applications or outdoor use, verify compatibility with operating temperatures and consider additional sealing or adhesive-lined tubing if environmental sealing is required.
