Heat-shrink tubing Yato YT-068672 530 pcs

Yato YT-068672 heat-shrink tubing set contains 530 individual pieces in assorted sizes and lengths, designed for insulating, protecting and organizing electrical connections. The tubing is made from a heat-shrinkable polymer that contracts when exposed to heat, forming a tight, moisture-resistant seal around wires and terminals. This set provides options for different wire gauges and connection types commonly encountered in electronics, automotive repairs, and general electrical work.

Advantages

The heat-shrink tubing offers reliable electrical insulation and mechanical protection, reducing the risk of short circuits and corrosion. Shrinkable material conforms to irregular shapes and creates a durable seal that resists abrasion and environmental contaminants. The variety of sizes and the large number of pieces in the set ensure that users have appropriate tubing for multiple repair and assembly tasks without frequent restocking.

Suitable for

• Insulating soldered and crimped wire joints
• Protecting wire splices in automotive and marine wiring
• Bundling and labeling wire harnesses
• Repairing damaged cable jackets and protecting terminals
• DIY electronics and prototyping projects

Key specifications

• Material: heat-shrinkable polymer
• Shrink ratio: typical 2:1 (contracts to approximately half the original diameter when heated)
• Contents: 530 pieces in a variety of diameters and lengths
• Operating temperature range: suitable for common electrical applications (room temperature to elevated temperatures during operation)
• Properties: electrical insulation, abrasion resistance, moisture resistance

How to use

Select a tubing piece with an initial diameter slightly larger than the wire or connector to be covered. Slide the tubing over the joint before making the connection when possible, or position it over the exposed area after the repair. Apply controlled heat using a heat gun, lighter with care, or soldering iron with a heat-shrink nozzle, moving evenly along the length until the tubing uniformly contracts and forms a snug seal around the conductor and connector. Allow the tubing to cool before handling to ensure a stable fit.

Usage recommendations

For consistent results, use a temperature-controlled heat gun and avoid direct flame to prevent overheating. Choose tubing with an appropriate shrink ratio and diameter for the wire gauge; leave a small overlap beyond the joint for full coverage. For applications exposed to moisture or vibration, consider using adhesive-lined tubing or supplementing with sealant where enhanced environmental protection is required.
