TICONNBlue 200PCS Heat Shrink Butt Wire Connector Kit, Insulated Waterproof Electrical Marine Automotive Wire Crimp Terminals Butt Splice (Blue200PCS)

I’ve had great luck with these crimping well and the heat shrink seems to create a decent seal.

Very easy to use and worked great.

Awesome product, can’t beat the price. Crimps very well and shrinks nicely

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

I used these to rewire my trailer and am really happy with the connections. I was working in an area with no power, so I had to use a lighter to heat them up and it worked fine. I'll never use the old non heat type butt connectors again, good value, will definitely buy these again.

Works great

I've used these for fixing the trailer hitch on my truck and connecting sprinkler values to my irrigation system. They are easy to install and seal up really well.

great quality and fast delivery
