TICONN Red 200PCS Heat Shrink Butt Wire Connector Kit, Insulated Waterproof Electrical Marine Automotive Wire Crimp Terminals Butt Splice (Red200PCS)

Good size easy to use great crimping. Functions well speedy shipping and good quality

By far one my most justified purchase ever on Amazon. For less than 20$ you have enough wire butt connectors to last the average tinker well for a year. I just ordered my second batch after finishing the first. I like that they seem to told wires far superior than other blue butt connectors, not to mention the shrink wrap melts evenly every time.

Good price, nice assortment. works well.

They seemed to work great and hold up well. Had a wire under my truck connected to one that had a huge chunk of frozen ice on it and it held it great

Excelente producto, muy facil de usar

These work great and produce a very strong connection.The crimping tool I have only crimps down to about 20 gauge, so for smaller wires I had to use some needle nose pliers and crimp it further. The tubes also will not actually shrink to 22 gauge, but you can gently crimp the ends with needle nose pliers while they are still hot and it will seal to itself. I guess technically that means it still works with 22 gauge, but not great. Doesn't look as tidy either.In any case, I give these the full five stars. For gauges 20 and below, which is 99% of what I work with, these work great.They crimp down tightly and the glue easily flows out of the tubes before hardening and forming a flexible, watertight seal.Next time I will order a larger box, I used quite a few on my project motorcycle. It had a bunch of electrical tape connections and cheap, low quality connectors throughout the harness when I bought it. These worked great to replace all those connections, and they are MUCH stronger than the cheap plastic connectors.

Item as described.

Always best to have in hand for butt splicing, and it's Heat shrink
