Waterproof Solder Seal Wire Connectors Kit, Electrical Insulated Wire Splice Heat Shrink Wire Connectors with 4 Gauges - 12-10, 16-14, 22-18, 26-24 AWG (250)

Everything seemed to work well with the two connectors I recently used. A regular heat gun and just a quick bit of work and all was solid and snug.I wish there was more of the pieces designed for the larger gauge wire (12 or 10 gauge) than the many for very small, thin wire. That being said, I knew it when I ordered the set.No complaints.

Have used about a dozen of these so far, from 18 gauge to 14 gauge. Chut the insulation back about 3/8", slid the wire ends into center solder, made sure the ends entertwined, used a heat gun on high, 10 seconds later all done. This is a great product. I will buy again.

Well made.

I feel they're a bit expensive for what they are, but they definitely have their place. I used a few of these connectors when repairing a car wiring harness where I couldn't fit a crimp connector and crimp tool in there. They make a great connection and I haven't had any issues with the installed connections.The only issue is it's a bit difficult to tell when the solder actually melts. While trying to melt one with a heatgun, the heatshrink insulation ripped itself from being overheated. I've never had that issue with any other heatshrink or waterproof crimp connector, so I feel that is a bit unacceptable.

Wow, what a game changer! I wish I would have found out about this product before, saves so much time and makes my work so much cleaner

Bidenomics cause this thing to be this small have yet to use but i can tell you can't be worth it it's maybe 3 inches by 2.5 inches

Have seen these before on Youtube & thought about buying them. Had not had a real reason to try them until recently with a small model railroad project I'm working on. Bought them yesterday, they arrived today. Already put them to work & then are the easiest way to quickly connect pairs of lines. I'm using multiple wires sizes & the pack I ordered covers 24-10 gauges. have used a few of the 14-16 & 18-22. Both worked like a charge on test pulls, so on the layout. Now have working track power. Ordering more cause im gonna need em. no more press fits that let go after trying these.

This product was recommended by an autobody shop on Youtube. I bought this based on their recommendation to rewire the lights on a boat trailer. These connectors made the whole process much easier and they work great. They make nice strong connection and so far they are keeping the water off of the connections. I would recommend this product, especially for trailer and vehicle wiring applications.
