Saltwater resistance

I normally don't write reviews. However I have wasted a lot of time effort and money on trying to find a good Marine wire connector. These have been on my boat trailer for this will be the third season. It goes in the saltwater almost weekly I bring it home and just hit it with the garden hose in the back around the lights I'm only replacing because I broke a light off and when I uncovered the wire loom and looked at the butt connectors they're just as good as the day I installed them. No corrosion on the connection portion nor is there any corrosion on The Wire outside of the connector. I highly recommend these for anyone submerging wiring into water

But connectors

I actually love these but connectors with solder inside they're not really hard to use. If you're unsure about these by the small box and just try them they are actually great. You just need a pair of wear strippers and cutters and a lighter is all I used.

Solder First

These seem pretty good, but I found that soldering first creates a much stronger mechanical connection. I used a soldering iron to tin the ends, then soldered them together. No twisting the wires. Then I slid and centered the connector over the joint and used a heat gun to shrink each end of the connector. I found that shrinking the connector ends first, then applying heat to the middle worked best. By soldering first, the joint was mechanically very strong. Without soldering, the joint could be pulled apart with very little effort. The connector comes with some type of low melting point metal that will create good electrical contact, but it does not seem to mechanically bond to copper conductors.As far as whether these are waterproof, we'll see. They seem like they will work well in wet applications, but until I see how they perform over time, I'll reserve judgement. I will be using these to connect sprinkler system control valves to the control wires. One of my control valve boxes almost always has standing water, so it will be a good test.

Just What I Needed

I bought these on a whim, but they turned out to be just what I needed. They are clean and efficient. I thought they worked really well.

These Splices are Great!

Simply join wires together with a western union splice, then thoroughly heat the splice with heat gun (needs fairly high heat), until solder melts, and you are done. Makes an excellent electrical connection, I spliced wires for vehicle coil packs without any issues.

Could be a little better

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.
