Works Very Well With The Right Equipment
These Solder Seal Connectors work very well BUT it is necessary to use the correct equipment to make a good connection. I used a NOEVSBIG 858D Hot Air Rework Station (Amazon ASIN # B07X5SFJNR)For those that say that the shrink tubing melts, I suspect that an open flame or a heat gun set above 900 degrees is being used. I tested the "plastic" shrink tubing and it starts to burn at 900 degrees Fahrenheit. 800 degrees Fahrenheit seems to work very well, melting the solder inside the tube but not burning the insulation. Pictures are attached.

These are easy to use connectors and seem to do a great job of both soldering the wire together as well as heat shrinking to prevent moisture from compromising the joint. Using in an automotive application and feel much more comfortable using these versus regular terminal connectors.

I installed a "tail tidy" on my Kawasaki using these. I've never installed one before and have never spliced a wire. Overall I had no clue what I was doing. I first tried to use a product I found at AutoZone that was similar to this but different. Those didn't work at all so I tried these. Such a life saver! I used a heat gun with these, and wow, so quick and easy to install while providing a great connection and hold! My bike looks great, all lights work, and everything has held up well after a month of use. I would definitely buy these again!

Reviewed in the United States on November 28, 2023
Style: Blue 16-14 AWGVerified Purchase
Read lots of reviews on this item where buyer stated it burns while applying or solder taking too long to melt and work properly, not the case for me. What works for me is using a mini butane torch and rotating the connector while applying heat, start from the solder area and work your way towards the ends of the tubing consistently back and forth; it worked flawlessly. Apply too much heat and you'll have a "bad" experience. The blue water seal works great, and the adhesive on the tubing melts just fine to create a water proof seal. It forms a strong bond

3.0 out of 5 stars I dont really trust these for important connections
Reviewed in the United States on December 17, 2023
Style: 110 pieces - 0.14 - 6.0 mm²Verified Purchase
I used them with a good heat gun and the solder just doesn't hold well at all - the first connection pulled apart easily the second the solder did not really melt well but he insulation deformed all around it. I tried the heat gun on both low and high the high does melt solder after a bit but the insulation melts around it. I still used them but joined with a soldering iron and "normal" solder first then put this over it to hold it together, if you dont need the solder for the connection (thats the purpose of these so not ideal) the insulation around it holds the wires well and looks like it should be water tight. I tried them, not impressed so when these are gong I won't get more, Im basically using them for heat shrink over my soldered connections at this point maybe you'll have better luck who knows??? if youre going to try them, watch a couple of videos first - fan wires out joint them together with a decent twist first to give you the best chance at a good connection.

Für den Preis kann man sich das zu Hause einmal hinlegen. Meistens braucht man doch immer nur die gleiche Größe, wo man sich dann überlegen muss, ob man lieber noch einmal mehr von der gleichen Sorte kauft. Für gelegentliche Eventualitäten hat man dann halt andere Größen im Schrank. Hat mich überzeugt, würde ich wieder kaufen!
