120 insulated wire connectors for soldering, 4 sizes 26-10 AWG butt connectors with heat shrink tubing, electrical connections for automobiles and motorcycles, shrink ratio 3:1

【Time Saving】 The heat shrink tubing cable connector requires no soldering or crimping. A 1500–2000 W heat gun (not included) is sufficient to heat the two cables evenly, creating a stable connection. This saves time and increases work efficiency.

【High-Quality Material】 The heat shrink connectors are corrosion-resistant and waterproof. Each connector features two waterproof hot melt adhesives, ensuring high tensile strength, a tight seal, and protection against leaks.

【Easy Identification】 The transparent cable connector sleeve allows for visual inspection during cable insertion, ensuring a successful connection. Solder connectors in various sizes and colors facilitate identification. A storage box with a grid allows for clear organization of the cable connectors. [Versatile Applications] Waterproof cable connectors are suitable for electronics projects and are ideal for the automotive, marine, aerospace, electrical lighting, and electronics industries. They offer the most standardized and safest method for repairs and modifications. [Notes] The matching connectors are available in four different sizes: 30 white (AWG 26-24), 40 red (AWG 22-18), 40 blue (AWG 16-14), and 10 yellow (AWG 12-10). When heating with a heat gun (not included), maintain a distance of 3 to 5 cm from the heat shrink tubing. Insufficient distance may cause the cable connector to break.
