EASY TO USE - Just strip your wires, insert them into the solder sleeve and apply heat. Soldered connections are made in seconds.HEAT GUN IS RECOMMENDED FOR BEST RESULTS - Apply heat with a heat gun while rotating the terminal continuously to ensure proper even heat distribution.IMPROVED TECHNOLOGY - Low temperature solder melts faster and prevents burns in the insulation tube.WATERPROOF - Heat activated adhesive heat will seal your connection and make it waterproof.MANY TERMINALS - This wiring kit includes 100 yellow 4-6mm terminals. Enough to complete multiple wiring projects.WATERPROOFConnection is waterproofWire corrosion protectionCan be submerged in waterHEAT ACTIVATED ADHESIVE RINGSCreates a tight sealResistant to stretching and vibration Color coded for easy identificationLOW TEMPERATURE SOLDERING SHEATHBegins to melt at low temperature (137C).Prevents burns in the heat-shrink tubing.A more efficient alternative to welding
