Soldering wires inside a tight engine bay or a damp boat hull is difficult. The QUADRIOS 2011C396 eliminates the soldering iron and the crimping tool. Each connector contains a precise ring of solder and a ring of hot-melt adhesive inside a heat-shrink tube. Slide the wires in, apply heat with a common heat gun, and the solder flows while the adhesive seals the ends.

The transparent tube lets you see when the solder has melted – a visual confirmation that the connection is complete. No guesswork, no cold joints, no corrosion later. The adhesive creates a waterproof barrier rated for -55°C to 125°C and 600V, suitable for under-hood automotive repairs, marine electronics, garden equipment, and industrial sensors where moisture is a constant threat.

This 120-piece assortment covers almost every wire gauge you will encounter in low-voltage work: white for 0.25-0.34mm² (AWG 26-24), red for 0.5-1.0mm² (AWG 22-18), blue for 1.5-2.5mm² (AWG 16-14), and yellow for 4.0-6.0mm² (AWG 12-10). Keep a bag in your service van or workshop and you will never waste time searching for the right connector size again.
