Heat Shrink Solder Seal Waterproof Wire Connectors

Create secure and waterproof electrical connections with these heat shrink solder seal wire butt connectors. Designed for quick and reliable cable splicing, these insulated terminals combine soldering, sealing and insulation in one simple connector, eliminating the need for crimping tools in many applications.

When heated, the integrated solder ring melts to create a strong electrical connection while the adhesive lining forms a waterproof seal around the wire. With an IP67 waterproof rating and a wide operating temperature range, these connectors are ideal for automotive wiring, marine electronics, outdoor installations and electrical repair projects.

Available in multiple sizes and colours, they provide a professional and durable solution for connecting different wire gauges.
