Heat Shrink Connectors - 270 PCS Insulated Electrical Crimp Heat Shrink Wire Connectors, Marine Automotive Copper Butt/Ring/Hook/Fork/Spade Disconnect Terminals Kits, CE SGS ISO Approved.

works good

Throw away your cheap Harbor Freight terminal kits and get this one. The metal in the terminals are much higher quality and grab/hold the crimped wire solidly, even if you use just pliers. The real game changer is the quality, transparent heat shrink insulator which provides both reinforcement for the crimp and strain relief by gluing onto the wire insulation. You can still see the status of your crimp (if wire slipped away from crimp) after heat shrinking so you can be sure that you have a solid electrical connector. The physical crimp and clear heat shrink provide inspectable redundancy so that you can be sure you have a permanent connection, and can verify your connection if the wire gets yanked. If you do very many connections, recommend buying ratcheting crimp tool and heat shrink gun about $20 each. Otherwise, pliers and a cigarette lighter will work.

These terminals are excellent. Very pleased with the purchase. Once heat is applied to the shrink portion of the terminals, it creates a very neat, and rigid seal for the connection. The length of the heat shrink portion is more than adequate and can even be trimmed slightly if need be. Be sure to use heat shrink crimps when crimping in order to preserve the integrity of the tubing. Great product, very satisfied.

These connectors are great. Variety of sizes included along with the tight seal formed when heating these make them the perfect kit to have for that trailer/vehicle wiring project you have. They seem to crimp better with a ratcheting crimper vs just using the wire strippers to crimp, but think that is more a result of tool used vs these connectors.

Used the butt connectors on my boat. I got tired of $5 for a pack of four terminals. These are just as good or better.

There was plenty of options as to size and type of connectors. There also was plenty of depth of any particular size. I used these to rewire a trailer and had more than enough to do it and again if I choose on down the road.

Metal is strong and crimping holds well. Only negative seems to be that when crimping hard the plastic sometime comes uncovered and exposes a small amount of metal. But after heating typically the excess heat shrink plastic covers these blemishes up. Very happy with the amount of assortment of sizes and different configurations.

The media could not be loaded.  😃I was surprised to see how good it seals the cables!😎It is good for electrical projects, like for car and boats repair.💪🏻💪🏻💪🏻I made a test on my a full force machine for 60 seconds and it passed the 8 pounds test, I did the 22 awg (American wire gauge) . This is an excellent buy for electrical DIY's ! 🔌⚡🔌⚡
