FEATURES:
▶Waterproof Seal - Dual-Walled tubing ensures waterproof seal and prevents wire corrosion. Hot melt adhesive & solder inside, sealed with advanced waterproof function.
▶Fast & Easy Operation - Just strip your wires, insert them into the connector and apply heat. Transparent sleeve provides precise inspection, easy control soldering process.
▶No Slip Wire Contact - Tubing reduces in size and solder will melt and flow through the stripped wires, ensure strong holding, avoids wires slipping out from the terminal.
▶Great wiring solution for hard to reach or limited space areas. Make properly soldered and waterproof connections in less than 30 seconds.
USING INSTRUCTIONS:
① Strip wire insulation 1/3 inch on both wire ends. Insert into the solder sleeve and twist the wire strands together.
② Continuously rotate the connector when using a heat gun to apply heat evenly around the solder until it flows into the wire strands.
③ Then apply heat to the two ends of the tubing until the adhesive flows and seals the wires.
④ Remove the heat and let it cool down for use.
Operating temperature range:
● minimum melting temperature of solder:138°C
● minimum shrinkage temperature:80°C
● working temperature: - 55℃-125℃
● shrinkage temperature:>160 ℃
