Heat Shrink Tubing Sleeves AWTools 270 pcs, assorted sizes, model AW18315

Set of 270 heat shrink tubing sleeves from AWTools in assorted sizes, model AW18315, designed for electrical insulation, cable repair and wire bundling. The assortment covers multiple diameters and lengths to accommodate common cables, splices, terminals and connectors in electronics, automotive and household wiring. The tubing provides mechanical protection, strain relief and environmental isolation for joints and exposed conductors.

Advantages

The set contains a wide range of sizes to match different wire gauges and connection types, reducing the need to cut custom lengths or buy multiple separate tubes. Made from heat-shrinkable polymer, the sleeves shrink uniformly when heated to provide a tight, insulating fit around conductors and connectors. The assortment format with clearly separable pieces improves workflow for DIY, maintenance and professional electrical tasks.

Suitable for

• Insulating soldered splices and crimped terminals
• Cable repair and sheath restoration on power and signal wires
• Bundling individual wires and providing strain relief at connector joints
• Protecting exposed conductors in automotive and household electrical systems
• Small electronics assembly and maintenance

Key specifications

• Total quantity: 270 pieces in assorted diameters and lengths
• Material: heat-shrinkable polymer (polyolefin-type)
• Shrink ratio: standard moderate shrink ratio suitable for general electrical use
• Operating temperature range: suitable for typical wiring and electronic environments
• Function: electrical insulation, mechanical protection and strain relief

How to use

Select a sleeve size slightly larger than the unshrunk cable or connector. Slide the tube over the joint or conductor before making the connection when possible. After soldering or crimping, position the sleeve to fully cover the exposed area and apply heat evenly from a heat gun, hot air tool or controlled flame until the tube contracts and forms a snug seal. Allow the sleeve to cool to complete the installation.

Usage recommendations

For consistent results use a regulated hot-air tool and heat evenly from a distance to avoid scorching. Choose a tube diameter that allows full coverage of the connection while ensuring sufficient shrinkage for a tight seal. For automotive or outdoor applications, verify the sleeve meets the required temperature and environmental resistance for the intended installation.
