IP67 Waterproof
Solder seal wire connectors come with IP67 water-resistant rating.
After being heated, they shrink and water will not be able to go inside,
preventing any short circuit issues.
Widely used on boat, vehicle, motorcycle, home, factory or marine.
High Success Rate
Our wire connectors are upgraded to use exclusive material in the butt connectors to avoid shrink tubing melting before solder ring. The success rate of connecting wire has been greatly improved.
Structure Features
Polyolefin Tubing Outside and Hot melt Adhesive Inside make connection strong and waterproof.

These heat activated solder shrink connectors work well, making secure butt connections.Please note that the proper amount of heat must be applied to activate/melt the solder. A heat gun is essential to properly use these connectors. Please also be aware hair dryer should not be used as a heating device, as it will not provide sufficient heat to melt the encapsulated solder.Once cooled, the connection is permanent and quite strong.I highly recommend these connectors.

These are incredible. I have used these now for multiple applications, from a car to sprinkler wires to vending machines. Just carry a heat gun and short extension cord for most places and you're set. You do strip the wires farther than you usually would with a crimp. The only thing I will say somewhat as a warning is that they work way better with stranded wire than solid wire. I have had a couple instances where solid wire pokes a hole in the coupler and I have to start over. Other than that, these are easy to use, guarantee a solid connection, go waterproof, and make it so that the connection isn't a massive piece of plastic that you will be able to see even under shrinkwrap. If you cover the wire with shrinkwrap afterwards, you won't even notice that there is a splice in the wire

Works good. I’ve done a few wiring jobs with these connectors and so far everything has held up after a few weeks. It does take a fair amount of heat to get the metal to melt, I had a one or two where the plastic melted before the metal did, that was a pain to have to remove.

These things are so cool. Best consistent butt connection I've ever been able to make. I use a heat gun with the narrow tip. You can burn through them if you're not careful. There is a fine line between hot enough to melt the solder ring and not melt the heat shrink. Once you get the hang of it you can do it every time. I lost his the little colored ring grips the wire too. You can kinda hit that part first to help hold the wire then hold it on the solder ring. I always do another layer of heat shrink just in case I burn through the one it's made of. I will definitely buy more of these. I hope they have different types of connectors in this same style. I do a lot of diy vehicle electrical work, these are my favorite now

I used the cordless DeWalt heat gun on high....say about 2" away from the splices. Forgot to use a reflector. Didn't burn or brown.....does take a good 30+ seconds to get the solder to melt. Mainly focus on the solder, and not the shrink tubing.The blue ones worked fine. When I was using one to one wire. But when I had to do 2 to 1 and used the large yellow...each one split....on the doubled up side. So I don't think they can handle uneven splices. Additionally. . when they split, the soldier is not "pushed" into the wore, so the soldier just pools up on the outside and doesn't bond. I didn't dock a star for this, as they work well....just not in this way (2 to 1 splice.....which the instructions don't even mention)

I tried 2 different heat gun and a small torch but none of them worked. The solder did melt but the connection didn't bond. When I cut the connector apart the wires basically fell apart. I also tried to use some flux on the wires but it didn't help. Would not recommend!!

makes the job done fast , instead of doing your connection with the old way , just use this product and you will see how solid the connection will be.Note : you need a heat gun to use this product.

Wish I knew about these years ago. Makes splices, particularly those that are exposed to the weather (i.e. automotive) quick and easy. Highly recommended.

Lots of different sizes all a different colour. Makes it very easy to distinguish which is which
