Heat-shrink tubing AWTools AW18310 — pack of 127 pieces, total weight 125 g

AWTools AW18310 heat-shrink tubing pack contains 127 pieces with a total weight of 125 g and is supplied in a plastic storage box with compartments and a size chart label on the inside of the lid. Made of polyolefin material, each sleeve shrinks to approximately half its original diameter and is designed for electrical insulation, cable protection and strain relief in repair, DIY and installation tasks.

Advantages

The polyolefin construction provides resistance to chemicals and elevated temperatures while maintaining electrical insulation properties. The organized plastic box with compartmented storage and an internal size chart makes selection and transport convenient for workshop or field use. Reduced diameter after heat application ensures secure coverage of joints, terminals and harnesses and helps prevent abrasion and moisture ingress.

Suitable for

• Insulating soldered or crimped wire joints
• Protecting and bundling wire harnesses and cable runs
• Strain relief on connector entries and terminals
• Repairing damaged insulation on single conductors
• Organizing cables in home, workshop or service environments

Key specifications

• Material: polyolefin heat-shrink tubing
• Pack quantity: 127 pieces
• Total pack weight: 125 g
• Shrink ratio: approximately 2:1 (shrinks to about half diameter)
• Temperature and chemical resistance suitable for electrical applications
• Packaging: plastic storage box with compartments and size chart on lid

How to use

Select the appropriate tube size from the box using the size chart, slide the tubing over the wire or joint, then apply heat evenly until the tubing contracts and conforms to the underlying conductor or connector. Heat can be applied with a heat gun, hot-air tool or lighter held at a safe distance; maintain constant movement to avoid overheating. Allow the sleeve to cool and inspect the seal before returning the assembly to service.

Usage recommendations

For reliable insulation and long-term performance, choose a tube with a slightly larger initial diameter than the component to be covered so it fully shrinks and provides secure mechanical support. Use a regulated heat source and avoid open flames directly on the tubing. Store the kit in a dry place and keep the size chart visible for quick selection during repeated tasks.
