## Summary description

YATO YT-81452 heat-shrink tubing, supplied in a pack of 100 pieces. Designed as electrical insulation sleeves for cable protection, strain relief and joint sealing. Suitable for repairing or insulating wiring, connectors and terminals in automotive, industrial and household applications where compact protective coverage and dielectric separation are required.

## Long description

YATO YT-81452 heat-shrink tubing — pack of 100 transparent electrical insulation sleeves designed to protect and seal wire joints, connectors and terminals. Each sleeve is 40 mm long with an initial internal diameter of 2.7 mm and is suitable for wires with cross-sections from 0.5 to 1.5 mm² (20–16 AWG). The sleeve contains a central ring of solder and two rings of heat-activated adhesive to provide electrical continuity and a moisture-resistant seal once shrunk and soldered.
Advantages
These heat-shrink sleeves are made of polyethylene (PE), which offers a higher shrink ratio (3:1) compared with common PVC types and maintains flexibility at low temperatures. The combination of an appropriate amount of solder binder and durable hot-melt adhesive ensures reliable mechanical and electrical joints and long-term sealing performance. PE construction also increases resistance to abrasion, punctures and many chemicals, making the sleeves suitable for a wide range of environments including automotive and industrial applications.
Suitable for
Insulating and repairing automotive wiring harnesses
Protecting and sealing splices in industrial control wiring
Household electrical repairs and connector insulation
Applications requiring flexible insulation in sub-zero or elevated temperatures
Key specifications

How to use
Slide a heat-shrink sleeve onto one conductor before preparing the wire ends. Strip and, if required, twist or tin the conductor ends, then position the sleeve so the solder ring aligns with the joint. Apply heat evenly (using a heat gun or controlled flame source) until the solder melts and flows between conductors and the tubing shrinks tightly around the connection. Continue heating until the adhesive rings flow and form a continuous seal; allow the assembly to cool before handling.
Usage recommendations
For reliable results, use a temperature-controlled heat gun and apply heat in a circular motion to avoid overheating local spots. Ensure proper wire preparation and correct sleeve size for the conductor cross-section. Avoid rapid bending at the sealed joint during initial cooling to preserve seal integrity.
