Solder. Seal. Insulate. All in One Connector.
Heat shrink solder seal wire connectors provide a convenient solution for joining two electrical wires without a separate crimping operation.
Each connector combines a pre-installed solder ring, transparent heat-shrink sleeve and hot-melt adhesive sealing rings for wire splicing, insulation and moisture protection.
The integrated structure performs three functions during controlled heating:
The transparent sleeve allows visual inspection of solder flow and shrinkage during installation.
Unlike conventional crimp butt connectors, solder seal connectors use heat to form the electrical joint.
With properly prepared wires and a suitable heat gun, installers can complete the connection without separate solder wire or crimping pliers.
The solder must fully melt and wet the conductors, and the sleeve must recover properly for a reliable connection.
Select according to the conductor cross-section, wire insulation diameter, installation temperature and environmental requirements.
Verify solder flow and complete end sealing before putting the connection into service.

They are used to join two electrical wires during cable extension, wiring repair and electrical equipment maintenance.
No. The connection is made by heating the pre-installed solder ring until it melts and bonds the prepared conductors.
The hot-melt adhesive rings help create a moisture-resistant seal around compatible wire insulation. Actual waterproof performance depends on correct sizing, installation and verified test conditions.
The solder ring should visibly melt and flow into the wire strands. The transparent sleeve should shrink completely, and both ends should form a proper seal.
White, red, blue and yellow models are available for wire sizes from 0.25 mm² to 6 mm², according to the product size chart.
