These heat shrink solder connectors join cables securely and permanently in three steps — no soldering iron, no electrical tape, no loose connections. Insert cable, apply heat, done: The integrated solder ring melts while the polyolefin heat shrink tubing seals the connection tightly and waterproof.

The set contains 50 color-coded connectors in four cable sizes — from fine signal cables to heavier automotive and marine cables. Each connector meets protection class IP67, making it suitable for vehicles, boats, outdoor installations, and DIY projects.
