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

They work .. don’t crimp to hard or you will split cover

Ok

I used these to install a stereo in my truck. They seem durable and work well.

Good product, but heat shrink plastic is thick. Not a problem with heat gun on HI but Id hate to do this with hair drying.

Great tohave in the shop

Used for splicing automotive wiring harness for engine swap.

Great product and easy to use and heat shrink works great protecting against water.

Does not work on small wires , which not there fought. I should have noted what size wire I had.

Works great for water tight connections

You don’t have to be an electrician to appreciate this set, but it may actually help to use it properly. Then again, if you have a crimper, heat gun, and two wires to be connected, you’re in luck. Simply strip the insulation from wires an appropriate length at the end and insert both ends into the crimp to collapse the metal tube to hold the wires. The stripped section should be fully inside the tube, but obviously not the wire insulation. Tuck on the wire to make sure you have a strong connection and then use a heat gun to sharing the tubing onto the wire jacket. That’s basically it.
