✅[Premium Solder]Solder seal wire connectors use high grade solder rings.When we heating the solder seal wire connector,adequate solder around the wire, melt and flow until form seal on the wire.
✅[Easy Use]Strip the wire insulation, insert the conductors of the wire into the connector, heat it with a hot air gun and rotate the terminal at the same time. The connector will reduce in size and adhere to the wire.
✅[Easy Identification]The different colors of the solder seal wire connectors make it possible to quickly determine the applicable wire by its color. 
✅[Wide Range of Applications]Whether you are working on your boat, motorcycle ,vehicle, home or scientific project. The lowest melting temperature: 138℃ (300℉); the lowest retraction temperature: 80℃ (180°F); working temperature: -55℃ - 125℃ (-122°F - 290°F).
✅[Advance Heat Shrink Tubing] Insulation tubing shrinks to 1/3 of its original size, providing the highest shrink ratio on the market. Heat activated adhesive seals the wire ends from the elements.
