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.

Just as expected

Solder Seal Wire Connectors

Very helpful and easy to use solder connectors which could be soldered, and sealed in a single application. Use a heat gun to get the shrink wrap to tighten on the wires and then wait a bit longer for the sealer and the solder to melt and fill in the spaces between. Solid connections without any wire nuts taking up tons of space.

Not easy to use

When Ii used a torch to heat it the shrink tube melted before the solder and when I use a heat gun it takes a long time and I'm not sure that the solder really melted into the copper wires

Thank you for your feedback. I am sorry for the issues you have been having with our solder seal wire connectors. 
Please note that we recommend to set the heat gun at around 400F. We also recommend to continuously rotate solder seal connectors when applying heat to ensure even heat distribution (this helps a lot to melt the solder ring faster). Finally, heat gun deflector nozzle helps to apply heat evenly to these connectors and again ensure faster solder melting.
Your satisfaction is a top priority for us. We have a 100% money-back lifetime guarantee. Please contact us and provide your order number. We will make every effort to determine the root cause of this problem, offer an effective solution, and ensure your complete satisfaction with Wirefy connectors. We will also send you a replacement for the connectors that did not come out well.

Thank you,
