350 Pcs Solder Seal Wire Connectors Heat Shrink Butt Connectors Kit Marine Waterproof Wiring Electrical Cable Splice Terminals for Boat Automotive RV Trailer

Ever use soldier and heat shrink? Tried holding two wires while soldering them? Forget all the pain with these things, these things are a dream, they help hold the wires together and solder and heat shrink at the same time. Did I mention how great they work.

The media could not be loaded. I think the reviews complaining about these connectors are not using them correctly. They worked perfect for me.They have a strong hold better than crimping, an airtight seal, and if you use the proper size for the wire you're working with they shrink to a glove tight snug. I've had zero problems with connectivity on any of my projects.These are not regular heat shrink tubes. You can't use a lighter or a torch. A lighter won't melt the solder, and a torch will melt the tubing and your wire before it melts the solder.I used a heat gun I got off of Amazon for $20. It has two heat settings, and a reflector on it so the entire tube was heatedly evenly in seconds. Spend just a few extra seconds around the solder ring.Don't immediately try to pull on the connection. Of course it's going to come apart while it's still curing. These are made to withstand shaking and movement, not heavy weight pulling. No one is going to come and tug on your wires to pull them apart.All that aside, I absolutely recommend these shrink tubes to anyone who's doing at least minor automotive electrical wiring. I installed a dash cam, aftermarket radio, and rear view cam into my car using these and they have held up perfect.Short of it is, don't blame the product for human error.

Can't say enough about these other than wow. I will buy nothing else, a heat shrink with solder. I was skeptical at first but these things are amazing. Strip your wires slide them into these connectors. Add a little heat, the solder melts the wires are connected and water tight. No crimping necessary. And they are solid

Medium quality, ease of use was good, Hold was fair to good..

Works great

Great product and works very well will def buy again !!

This kit gets three stars because size wise is great. The sizes fit almost everything you could think of when needing to solder joints for wiring cars. I used this on my stereo equipment and lighting for my truck. The fiction great and hold together very well. They are easy to use and make wiring much easier than twist nuts. My concern on these is the solder itself. I have had a few that does not want to melt the solder. Most of them melt within seconds with a heat gun, but I have some that wouldn’t melt, even on the highest setting. Because if this I’m giving a 3 star review. For the price if this set, they aren’t terrible, but could be better.

Banging deal on these hard to find connectors and they work great
