Haisstronica 220PCS Solder Seal Wire Connectors - Waterproof & Heat Shrink Electrical Connectors Kit (20Yellow 40White 80Red 80Blue)

I had a hard time finding electrical connectors anywhere that were anything at all other than the basic overpriced non-sealing but connectors. These soldered together easily and seem to be weatherproof, but I can't say for sure as they were just installed. They are a little tricky because you have to hold the wires straight for a little bit while the solder hardens. Good value for the money though.

I used about 100 of these to create well sealed wiring connections. On a note the provided solder in the tube may not be enough to solder 18-22 awg wiring you will want to solder the wires first then slip these over and heat up

These are the best wire connectors I have ever used!

Tried these to wire a car stereo. Worked OK but not the best.

Product is awesome. Delivery time over two weeks is not.

works great

I was worried the plastic would melt first and not contain the solder but that's not the case. These work surprisingly well.

great

este tipo de conectores ayuda mucho cuando estas rehaciendo arneses de vehículos el único inconveniente es que forzosamente se necesita una pistola de calor (no sirven los encendedores ni las pistas secadoras de cabello no generan el calor suficiente )

I have seen bad reviews on these, but feel they are wrong. I used them for the first time and they worked great. I used a torch type lighter and everything melted perfectly, including solder. The key is to let everything cool down and harden, and be careful not to over heat them. So A++ on quality and delivery speed.

Not quite as simple and quick as you may assume, they require a prolonged period of heating. The solder doesn’t fully penetrate the wires like the traditional Method. Definitely recommend using them in tight areas/inside the vehicle.

Used these wiring my new bike , very convenient and worked as expected, just have to be careful with the heat gun and have good clean connections.

The solder takes a while to melt and you swear its going to light on fire but they work as described.
