Durable, weatherproof butt splice connectors designed for secure string-light and low-voltage wiring connections. Each bag contains 100 adhesive-lined, heat-shrink connectors engineered to seal out moisture and provide a dependable electrical joint for outdoor lighting runs.

  • Quantity: 100 connectors per bag—ideal for installers and seasonal lighting projects.
  • Waterproof seal: Adhesive-lined heat-shrink tubing forms a moisture-resistant barrier after heating.
  • Secure crimp: Built-in crimp area ensures a reliable mechanical connection before heat-shrink activation.
  • Color-coded: Pink tubing for easy identification and fast sorting on the job.
  • Simple installation: Insert wires, crimp to secure, then apply heat to activate the adhesive-lined tubing.
  • Designed for string lights: Use one connector per wire (four connectors per full connection) for consistent, long-lasting joins.

These connectors are suited for outdoor string lights and similar low-voltage applications where a compact, weatherproof splice is needed. Store in a dry place and apply heat evenly during installation to ensure the adhesive flows and the tubing fully conforms around conductors. Keep out of reach of children and follow local electrical codes when performing wiring work.
