Revolutionary IP67 Waterproof Solder & Seal Technology - A waterproof seal is created easily by placing stripped wires into the solder sleeve and applying heat. Dual-walled heat shrink tubing with hot-melt adhesive prevents wire corrosion, and you will never have to worry about water damage.
Thicker Tubing To Prevent Burns - A low-temp solder sleeve with thicker heat shrink tubing prevents solder melting through the insulation tubing.
Color-Coded And Compliant With All Standards - For easy identification, the connectors are color-coded along with a handy wire size chart located on the box. Connectors comply with ROHS, ISO 9001:2008, SGS, and CE standards.
An Amazing Solution For Hard-To-Reach Areas - Solder seal wire connectors work excellently in limited-space areas, as solder and seal electrical terminals do not need crimping.
In an innovative fashion, Wirefy has set the bar high for solder seal wire connectors, and how easily and efficiently they can be used. With a 110 piece kit or a 50 piece kit, you’ll always have the revolutionary connectors you need for any wiring project you have in mind.
The product works as advertised, but you have to practice to get it right. My first few attempts using a small butane torch I applied too much torch and burned the heat shrink before the solder wicked onto the wires. But after these practice runs, its pretty easy to use.
