What you get 300 PCS spade heatshrink connectors. Each piggyback terminal incorporates 1 male and 1 female spade, forming a secure 3way connection that can be disconnected in seconds. Key benefits and features Secure 3way connections: piggyback design with both male and female spades enables a reliable threeway join that can be quickly separated when needed. Durable heatshrink tubing: PE material with gel inside; after heating, it tightens onto the wires for a solid, sealed bond. Shrinks to one third of its original size, helping prevent wires from coming loose. conductivity: connectors are made of pure copper, providing stable and efficient electrical transmission with low resistance. Easy operation: userfriendly design suited for electrical projects. Quick to connect and disconnect multiple times, offering a safer and faster alternative to traditional splicing methods. Material and construction Spade connectors: pure copper for conductivity and dependable performance. Heatshrink tubing: PE with gel inside, designed to seal and protect wires after heat application. Shrinkage: final size becomes one third of the original, aiding in a tight, secure hold. Applications and use scenarios Automotive and motorcycle wiring: ideal for rapid, secure connections in harnesses and accessory wiring where quick disassembly might be needed. DIY electronics and project builds: convenient for prototyping and assembling removable, threeway connections in hobby projects. Home appliance and upgrades: useful for replacing or upgrading wire terminations in electrical devices, enabling faster servicing and maintenance. Usage tips Ensure all connections are clean and dry before applying heat. Use a suitable heat source to evenly shrink the tubing around the spade terminals for a tight seal. Inspect connections after shrinkage to confirm a secure fit and proper alignment.
