200 Pieces Insulated Wire Connector Solder Joint, 4 Sizes 26-10 AWG Butt Connectors with Heat Shrink Tubing, Electrical Terminals for Automobiles and Motorcycles, 3:1 Shrink Ratio

【Save Time】 The cable connector with heat-shrink tubing requires no soldering or crimping. A 1500W-2000W heat gun (not included) is all that's needed to evenly heat the two cables for a stable connection, saving time and improving work efficiency.【High-Quality Material】 The heat-shrink connectors are corrosion-resistant and waterproof. Each welded connector has two waterproof hot-melt adhesives to ensure high tensile strength, a watertight seal, and leak-proof protection.【Easy to Identify】 The cable connector sleeve features a transparent design, allowing for visual inspection when the wire is inserted, ensuring a successful connection. Solder wire connectors in various sizes are available in different colors for easy identification, and a storage box with a grid allows for neat sorting of the cable connectors. 【Widely Used】 These waterproof cable connectors are suitable for electronic engineering projects and are ideal for the automotive, marine, aerospace, electrical lighting, and electronics industries. It's the most standardized and safest way for you to repair or modify. 【Warm Tips】 The mating connectors are available in 4 different sizes: 40 pieces white (AWG 25-24), 80 pieces red (AWG 22-18), 60 pieces blue (AWG 16-14), and 20 pieces yellow (AWG 12-10). When using a heat gun (not included), keep a distance of 3 to 5 cm from the heat-shrink tubing. If the heat gets too close, the wire connector will easily break.
