THE WELDING PROCESS IS SIMPLE: In the process of welding with the heat shrink wire connectors, no other crimping tools or welding machines are needed. NOTICE: It is generally recommended to use a heat gun for heating to complete a safe and compact connection. If you must use a lighter, you can only use the inner flame, not the outer flame (the temperature of the outer flame is high, which will scorch and burn the product black).
EXCELLENT WATERPROOF AND SEALING PERFORMANCE: Shrinking ratio: 2:1. Each solder seal wire has two hot-melt waterproof rubber rings, which can be bonded in a short time while effectively improving the waterproof performance and preventing corrosion.
WIDE RANGE OF APPLICATIONS: This wire connectors can be used in cars, motorcycles, boats, and home circuits, and even in scientific research projects, you can use this electrical connectors kit to perfectly connect your faulty circuits and solve your needs.
TRANSPARENT PACKAGING AND ORDERLY ARRANGEMENT: These heat shrink wire connectors will be arranged in the storage box in an orderly manner, which is very convenient to store, take and carry. Different color tubes correspond to different connector sizes. You can easily find butt connectors of various sizes you need.
