300 pieces spade heatshrink connectors: each piggyback terminal includes one male and one female spade, enabling a secure 3way connection that can be easily disconnected in seconds. Heat shrinkable tubing: made from PE material with an internal gel, which after heating tightly bonds to the wires. Shrinkage ratio is 1/3, providing a strong, reliable wrap that protects the connection and helps prevent wires from coming loose. conductivity: spade connectors are made of pure copper, delivering stable and efficient electrical performance with low resistance. Easy to operate: designed for userfriendly use in electrical projects. Quick to connect and disconnect multiple times, offering a safer and faster alternative to traditional connection methods. Compatibility and performance: fits standard male and female spade terminals; piggyback design supports a 3way connection for flexible wiring options. Practical applications: Automotive and motorcycle wiring harnesses, battery leads, and auxiliary circuits that require quick disconnects and reliable splices. DIY electronics projects and home wiring tasks where multiple taps or branches are needed. RC hobby setups, solar panel wiring, and general electrical projects that benefit from reusable, secure spade connections.
