132PCS Solder Seal Wire Connectors, Professional Heat Shrink Butt Wire Connectors, Cooclensportey Solder Stick Wire connectors for Motorcycle, Automotive, Marine with Anticorrosion and Waterproof

This is an excellent product. To be able to have a soldered connection without the hassles of setting up the soldering iron is very quick and convenient. The connections are very durable as well, they will not pull apart easily. As long as I have these I don't see myself using my soldering iron anytime soon.

Needed to solder speaker wires in the door jam of my 2014 F150. Worked perfectly; Also worked on the wire for the door ajar sensor. Rather than buying a new wiring harness, I bought these and they did the trick!

I should have watched the video posted here from Amateur Photographer, which is really well done. I've used these a few times and I've been using a mini torch, which I think is too intense, as it seemed to slightly melt the plastic.I waved the torch constantly, in an attempt to evenly distribute the heat, but it still melted the plastic a bit. In these cases I also used heat shrink tubing over all of it and it seems to be doing a fine job.Even though I didn't get optimal results, I still give 5 stars because I know what I did wrong, and the price is amazing.

Very convenient & strong. I used them to hardwire a motorcycle stator to the rectifier, worked well just be carefull not to over heat them.

The 430PCS solder seal wire connectors from Cooclensportey are a fantastic addition to my toolkit! These durable heat shrink butt connectors are perfect for automotive, motorcycle, and marine applications. 🌟 The built-in solder stick ensures a strong, reliable connection, while the anticorrosion and waterproof features provide peace of mind for long-lasting performance. Installation is straightforward, and the connectors heat shrink perfectly for a professional finish. I’d be thrilled if Amazon or the vendor sent me additional wiring products to try out! If you need high-quality connectors that can withstand tough conditions, I highly recommend this set!

This is a good product that is well packaged and does the job exactly as described.

I should have been using these years ago! Great for any connections in the weather, or under the hood. The solder of melts for a good connection, and the heat shrink keeps the water out. I seem to use these for most every connection now.

I found using these connectors is much more convenient when working with small wire and much faster than a crimp and heat shrink. Took some practice to get the proper strip length and solder temp but they really do work well.
