Color: Heat Shrink Tube Set Package Includes: 1 x 328PCS (8 sizes) 2:1 Heat Shrink Tubing Customized: Yes Material: Steel A practical heat shrink tubing set designed for electrical insulation and wire protection. This kit includes 328 pieces across 8 sizes with a 2:1 shrink ratio. Customization is available. The material is steel. Key benefits - Wide size range: 8 sizes to fit a broad range of wire diameters, reducing the need for multiple separate tubes. - Effective insulation and protection: Shrinks tightly around wires and cables to help seal against abrasion, moisture, and environmental exposure. - Efficient shrink ratio: 2:1 shrink ratio allows a secure fit on many common wire sizes, simplifying assembly and repairs. - Easy to use: Cut to length, slide onto the wire, then apply heat with a heat gun or hot air until the tube contracts to fit. - Durable and portable: The kit is designed for long-term use and convenient storage and transport. Use scenarios - Automotive wiring and harness protection: Insulate and protect electrical connections, relays, and small wiring bundles in engine compartments or dashboards. - Electronics projects and cable management: Organize and insulate sensor wires, power leads, and prototype wiring in hobby or DIY builds. - Household appliance repairs and maintenance: Quickly insulate exposed conductors and reinforce wire splices inside appliances and power tools. Usage tips - Select the appropriate size for the target wire diameter. - Cut the tube to the desired length, slide it over the area to be insulated, and position it evenly. - Apply heat evenly with a heat gun or hot air source until the tubing fully shrinks and conforms to the wire. - Allow to cool before handling to ensure a secure, protective seal. Customization notes - The package is listed as customizable. If you have specific sizing, color, or packaging requirements, request customization to better suit your project needs.
