Quality Heat Shrink Cable Connectors are available at Smart Water Shop:
Heat Shrink Cable Connectors are heat-shrinkable caps designed for simple, fast sealing of multiple wire connections without the need for soldering or welding. They are the perfect lighting and electrical addition to any circuit or system, as they conveniently and quickly seal multiple wires together for easy operation and installation of powered products and displays. To use, simply apply direct heat to a cable connecter, causing it to shrink down and hold firm to cables. Resin contained in each cap acts as a sealant against weather and assists in coating raw copper cable.
