YATO YT-81441 Heat Shrink Solder Connectors 0.5-1.5mm²
Heat shrink solder connectors with built-in solder combine soldering and insulation in a single component. The product is designed for permanently joining 0.5-1.5 mm² copper wires while protecting the joint against moisture and mechanical damage.
Features of heat shrink solder connectors
Three-layer sealing construction
The connector has a central ring of solder with two rings of hot-melt adhesive on either side. When heated, the solder melts and joins the wires while the adhesive forms a waterproof barrier – this removes the need for separate soldering and insulating of the joint.
Solder melting point of 105°C
The built-in solder melts at 105°C, producing a stable joint between copper wires. The connector shrinks at 80°C – the PE material shrinks before the solder melts, ensuring the correct sequence during the joining process.
Internal diameter of 2.7 mm before shrinking
This is the connector's initial diameter, sized for 0.5-1.5 mm² wires. When heated, the connector shrinks around the wires, pressing the solder and adhesive into place. Check the outer diameter of your wire – it must fall within the connector's compatible range.
Polyethylene (PE) material
The polyethylene used in heat shrink connectors offers flexibility, resistance to chemicals and insulating properties. Once shrunk, it forms a tight seal that protects the joint against moisture, dust and vibration.

Applications of heat shrink solder connectors
- Vehicle electrical systems – joining wires in 12V/24V circuits with protection against moisture and road salt
- Cable repairs in consumer electronics – joining broken leads in domestic appliances and audio-visual equipment
- LED lighting installations – fitting LED strips and modules that require waterproof connections
- Alarm and CCTV systems – joining signal cables in low-voltage installations
- DIY projects and hobby electronics – making durable connections in prototypes and custom-built devices
- Car audio installations – joining speaker and power cables in car audio systems
- Power cable repairs – restoring damaged leads on power tools (in compliance with safety standards)
- Outdoor installations – joining cables in garden lighting and outdoor automation systems
Fitting heat shrink solder connectors
Preparing the wires
Strip about 5-7 mm of insulation from each wire. The wires should be clean, free of oxides and contamination – if necessary, clean them with abrasive paper or a wire brush. Slide the connector onto one of the wires before joining them.
Positioning and heating
Push both wires into the connector so that they meet in the middle, at the solder ring. Use a heat gun or a gas lighter to heat the connector evenly – start in the middle and move the heat source towards the ends. The connector shrinks first (80°C), then the solder melts (105°C), and finally the sealing adhesive activates.
Checking the joint
Once cool (about 1-2 minutes), check that the connector fits tightly around the wires and that melted solder is visible at the ends – this indicates a correct joint. Gently pull the wires in opposite directions – a correctly made joint should withstand the pulling force.
