Heat Shrink Tubing Sleeves AWTools set 128 pcs, assorted lengths and diameters

Set of 128 heat shrink tubing sleeves by AWTools provides a selection of insulated tubing in assorted lengths and diameters for electrical insulation, wire bundling and cable repair. The kit contains multiple pieces in common sizes designed to protect electrical connections, provide strain relief and enable colour-coding of wiring in electronics, automotive and household applications where heat-shrink protection is required.

Advantages

This AWTools heat shrink tubing set offers a wide range of sizes in a single kit, reducing the need to purchase individual tubes for different tasks. The materials are suitable for creating a tight, insulating fit over splices and exposed conductors when heat is applied, improving mechanical protection and insulation. Assorted lengths and diameters make it easier to match tubes to wire gauges and connector sizes, while the inclusion of multiple pieces supports repeated repairs and installations.

Suitable for

• Insulating soldered joints and spliced wires
• Bundling and identifying wires in automotive and marine systems
• Protecting cable ends and providing strain relief on connectors
• Small electronics repairs and hobby projects
• Household wiring maintenance and temporary fixes

Key specifications

• Quantity: 128 pieces in assorted lengths and diameters
• Material: heat-shrink polymer (sleeving suitable for electrical insulation)
• Range of diameters: assortment covering multiple wire gauges for insulation and repair
• Lengths: assorted lengths to suit short splices and longer cable coverage
• Colour options: mixed colours for identification and colour-coding
• Intended use temperature: designed to shrink when heat is applied (use with heat gun or suitable heat source)

How to use

Select a tube with an expanded diameter slightly larger than the unshrunk wire bundle or connector, slide the tubing over the joint or exposed conductor, then apply heat evenly using a heat gun, lighter with caution, or other appropriate heat source until the tubing contracts to form a tight insulating layer. Allow the tubing to cool to room temperature before handling. For best results, ensure surfaces are clean and dry and avoid overheating to prevent damage to nearby components.

Usage recommendations

Use a controlled heat gun at moderate distance for even shrinking and to avoid scorching nearby insulation. Choose tubing with an appropriate shrink ratio and diameter for the wire gauge; when colour-coding, use contrasting colours for clear identification. Keep spare pieces from the set for future repairs and verify compatibility with the operating temperature range of the installed cables.
