Durable Connection: The size of the tube is reduced, and the solder will melt and flow through the stripped wire to ensure a firm fixation. Your wires will never slip out of the connector. Double-Wall Design: Polyolefin tube on the outer ring and hot-melt ring on the inner ring, which can effectively improve the waterproof performance and prevent wire corrosion. Easy to Use: When stripping and inserting wires, the transparent sleeve provides precise inspection. The color-coded pipes make it easy to pick up and use. Widely Applications:Suitable for DIY wires and other outdoor applications. Storage: Comes with a plastic box, easy to carry and hold.
