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.
I tried to splice a couple wires under a dash in my car. I could not get the solder to melt, the shrink wrap would turn black and the wires could be pulled apart. Maybe you will have better luck.
Hi Sam Giovanetti,
Thank you for your feedback. I am sorry for the issue you have experienced with our solder seal wire connectors.
It looks like you were using a lighter as the shrink wrap was getting burnt and turned black.
Please note that we recommend to use heat gun as a heat source. You can also use a mini blow torch if the space is tight. It is important to rotate solder seal connectors when applying heat to ensure even heat distribution (this helps a lot to melt the solder ring faster). Did you happen to rotate the connectors when applying heat? Finally, heat gun deflector nozzle helps to apply heat evenly to these connectors and again ensure faster solder melting.
