ELECTRAPICK 200Pcs Heat Shrink Butt Connectors, Waterproof Insulated Electrical Terminals Kit, Electrical Wire Crimp Connector for Automotive Marine Boat Truck Stereo Joint

These are as good a splice as any I have been able to find on Amazon and I have purchased many different varieties in my pursuit. For me it's all about the crimp barrel. If the crimp barrel isn't any good then the completed splice isn't any good either. The crimp barrel on these splices appear to be a solid thick walled cylinder without a seam. That makes all the difference in the world as the seam is the weak spot. The shrink sleeving is just a nice bonus. I'm very satisfied for a change.

excellent

Great way to get a couple hundred butt slice connectors for low voltage wiring, like trailer lighting. They crimp solidly, material heat shrinks around the wires, and interior of plastic has a thermoset glue that bonds to the wire insulation for waterproofing the joint, making them perfect for undercarriage wiring on trailers :-)Only complaint is lack of quality in the included storage container. Our pack arrived with a broken latch. Connectors inside were fine, but one latch was missing entirely...the broken part was not even inside the shrink wrap keeping the kit sealed, so it appears to be shipped from factory that way :-) While I wanted the connectors more than the storage aspect, it is a ding on quality control to ship a set with a broken storage case to Amazon, for subsequent order fulfillment. I had another container that fits my tool bag, so I'm not beholding to the included one, but still...

These heat shield butt connectors work excellent. They are waterproof and can be used for outdoor, marine or auto use. My husband uses these types of connectors often. He said they shrink perfect for a waterproof connection which he needs often for anything on our boat. This box of 200 should last him for many years.

I'm not sure what the 1-star review is about, dude needs to elaborate.I just used approximately 30 of the 18-22 gauge butt splices to repair a transmission wiring harness. They worked great. The ferrules are notably thicker than the connectors that came with the new plugs. Strong mechanical hold and the glue seems to get good coverage without making a mess.Glad I have another 150+ pieces for future projects.

These seem to be a really good quality for not a ton of money. they are in fact plated copper. I dissected one to test it, they looked to be aluminum at first. They shrink down really nicely. There are some pretty classic typos on the packaging regarding what gauge goes in what but it is correct on the butt splices. When I run low I will certainly buy these again.

The wire fits in them perfectly and they are easy to crimp. Apply some heat to them after and the heat shrink, shrinks right down and seals tight to the wire. I have used these on a boat trailer for redoing the lighting and they seem to keep the water out and have had no issues so far.

I bought these to rewire a boat trailer and wanted water tight connections. These worked great. They shrunk down with a heat gun and seem to be keeping the water out. Must have for a boat trailer wiring job!
