Heat-shrink tubing YATO YT-81453 — 100 pcs pack

YATO YT-81453 heat-shrink tubing — 100 pcs pack provides transparent, glue-lined insulated sleeves designed to protect and seal electrical connections. Each 40 mm long tube has an internal diameter of 4.5 mm and is intended for wire cross-sections 1.5–2.5 mm² (16–14 AWG). Constructed from polyethylene (PE) with a central ring of solder and two rings of hot-melt adhesive, these sleeves combine mechanical protection, corrosion-resistant soldered joints and environmental sealing for general repair, wiring harnesses and professional or DIY electrical work.

Advantages

The PE construction offers a 3:1 shrink ratio for a tighter wrap and easier fitting over larger cable diameters, preserved flexibility at sub-zero temperatures and improved resistance to abrasion, punctures and chemicals compared with PVC alternatives. The central ring of solder binder ensures a reliable soldered connection by flowing between conductor strands, while the two adhesive rings form a resilient seal that retains elasticity over time. Tubes are specified to begin shrinking at around 80 °C and the solder binder melts at approximately 105 °C, enabling predictable installation performance.

Suitable for

• Insulating and sealing splices in automotive wiring harnesses
• Repairing household and industrial electrical cables
• Protecting connector joints exposed to moisture or mechanical stress
• DIY electronics and hobby wiring projects requiring sealed connections

How to use

Slide the heat-shrink tube over one conductor before making the electrical joint. Join conductors by twisting or soldering as appropriate, then position the tube so the central solder ring is centered on the connection. Apply heat evenly with a heat gun or appropriate heating tool until the tube contracts, the solder binder flows and the adhesive rings melt to form a seal. Allow the assembly to cool so the solder solidifies and the adhesive regains elasticity.

Usage recommendations

Use a regulated heat gun or controlled heating source to ensure even shrinkage and proper solder flow. Avoid open flames that can overheat or damage surrounding insulation. For automotive or outdoor applications, ensure the joint is clean and free of corrosion before applying the sleeve to achieve the best mechanical and environmental protection.
