400 Pcs Heat Shrink Butt Connectors, 4 Sizes (26-10AWG 0.25-6.0mm²), Waterproof Cable Connector Set, for Automotive, Marine, and Electronics Industry

Premium Material: These heat-shrink tubing connectors consist of a polyolefin outer tube and an inner layer coated with hot-melt adhesive. When heated, the high-quality heat-shrink tubing shrinks at a 3:1 ratio, forming a watertight seal that protects the wires from moisture and corrosion after soldering. Package Contents: The 400-piece solder connector kit includes four different sizes of heat-shrink tubing connectors: 100 red (AWG 22-18), 40 blue (AWG 16-14), 30 white (AWG 26-24), and 10 yellow (AWG 12-10), as well as 275 pieces of heat-shrink tubing. Easy to Use: The heat-shrink tubing connectors are transparent for easy visual inspection, ensuring a successful connection. Using soldered connector tubes is simple: just place the stripped wire into the solder point and maintain a constant temperature using a heat gun to complete the solder joint. Convenient Packaging: The heat-shrink electrical connector kit is easy to store and comes with a reusable case, allowing you to transport the connectors safely and systematically to meet your various needs. Wide Range of Applications: Heat-shrink bullet connectors are suitable not only for the electronics, railway, shipbuilding, automotive, motorcycle, and aerospace industries, but also for other industrial and outdoor applications.
