haisstronica 340PCS Solder Seal Wire Connectors Kit, 5 Colors/5 Sizes | 26-10 AWG, Wire Gauge Markings, Clear Sleeves, Hot-Melt Adhesive Rings, Compartment Storage, Automotive Wiring

Works like magic! Great way to join wires for a positive connection. Waterproof after you heat the connection. A better alternative to butt connectors

Works as it should. Easy to work with

These wire connectors are just genius. Forget about the old crimp connectors, these are easy to use and provide a reliable joint that is also sealed. I've been having problems with low voltage landscape lighting connections, these solved that problem in no time. Bob G, Frankfort, IL

I got tired of the old plastic crimp connectors so I wanted to try this style. However, working on tight quarters where you don't have full access to the wires you are trying to connect to introduces limitations, because a wire stripper is needed and you have to have some wire length available to strip the wire well. In any case, you can loop the connector through to at least one side of the wiring, connect the wire leads, then move the connectors over the wire junction in the right location. With a heat gun, I tried to avoid over-heating but it's hard to get the solder portion to melt without melting the plastic first. Keep in mind there is residual heat being absorbed into the wire. I might try using flux and pre-tinning next time. The diameter of the connector was the perfect size and thickness for the specified wire gauge. The glue and heat shrink portion definitely helps make a nice water seal compared to any other methods. The electrical connection is working, but I will have to keep an eye on it because I just don't think the solder melted necessary. It's supposed to be between 280 and 320 deg F, so the 400 deg F setting on the heat gun should be fine, but it didn't feel like it. When I upped the temperature, the plastics were in meltdown mode. I haven't seen any videos that show exactly how to apply the heat for how long and what temperature.

Works as promised. Good product for the price

So easy to use and have proven weather proof so far!

Product is exceptional at connecting 2 wires and shrimp wrapping the ends as it advertises. It is even good at soldering an end onto a wire while it shrinks over the connector end by cutting one side or the shrink wrap back part way. However there are no instructions so you have to guesstimate how long to heat the connector with the heat gun while turning to heat all sides evenly. It isn't that hard since the shrink covering is clear and you can see the solder melt. Not only that but the solder seems to melt when the shrink wrap is finished shrinking so so connection and seal finish around the same time. After completion let it sit and cool a few seconds before moving or pulling the wires to allow perfect connection. The locking clips on the box are the usual cheap quality you get on a typical shrink wrap plastic box that won't last very long so close carefully. The larger quantities of this product appear to also have a better sealing box. I have been a mechanic for nearly 50 years and this is as critical as I could make the review. The main thing is this is clearly a great 5 star product for connecting wires.

These work great! I used these to connect my sprinkler low voltage wire. They work great. I used my heat gun to shrink them🤙🏽.

Muy completo y bueno para soldar cables electronicos como en tiras led por ejemplo, con un encendedor, sin mas.

Richtig gute Teile, Kabel zusammen stecken erhitzen fertig!!!

Excelente 👌🏼 para empalmar cables sin herramientas ni nada , diferentes tamaños

Fini les gros pâté et des soudures qui ne tiennent pas.
