Do you still have trouble with wire connecting jobs? These durable, reliable, waterproof solder wire connectors are here to make your work easier.

FEATURES
- Wide Application - Ideal for use in marine and automobile applications.
- Easy to Use - No need to crimp; just apply heat to complete. This provides a one-step connection that is soldered, insulated, and sealed.
- Fantastic Design - The dual-walled design ensures a waterproof seal and prevents wire corrosion. The outside polyolefin tubing provides insulation and improves pullout strength, while the internal hot melt adhesive and solder ensure wires are tightly connected and prevent them from slipping out of the terminal.
- Convenient - Specific colors for specific sizes make them easy to identify and select. The transparent sleeve allows for precise inspection when stripping and inserting wires.
HOW TO USE
- Prepare wires.
- Select the correct heat-shrinkable butt connector.
- Strain the wires and fix them into the pre-fluxed solder sleeve.
- Evenly heat the connector with a heat gun until it is completely melted and fully recovered.
- Remove the connector from the heat gun and wait for it to cool.
