Solder Wire Connectors (Heat Shrink Solder Sleeve) A solder connector, also known as a heat shrink solder sleeve connector or solder splice sleeve, is a type of electrical connector used for joining or splicing wires together. It provides a convenient method for creating a secure and insulated connection between wires, typically in situations where a permanent and waterproof connection is needed. How to: Apply heat to the solder sleeve using a heat gun or other suitable heating tool. As the heat is applied, the solder preform inside the sleeve melts and flows, creating a soldered connection between the wires. The heat also causes the tubing to shrink and the adhesive to activate, providing insulation and protection. A solder sleeve consists of three main components: Heat-Shrink Tubing Transparent Solder preflux ring Adhesive color rings
