Features:

  • ❀【Easy to Use】– NO Crimping required. Transparent sleeve provides precise inspection when inserting wires inside. Simply position the stripped wires into the solder sleeve and apply heat to finish the connection.
  • ❀【Waterproof】- Unique Dual-walled Design: polyolefin tubing outside and hot melt adhesive inside. When heat is applied, polyolefin tubing reduces in size and adhesive flows inside the insulation, creating waterproof seal and preventing wire corrosion.
  • ❀【Easy Identification】- Color-coded tubing makes it easy to identify the right size of the connector for every application. Ideal used for Motorcycle, Automotive, Marine and other Home Applications.
  • ❀【Compliant with All Relevant Standards】- Sopoby solder seal wire connectors are compliant with ROHS, ISO 9001:2008, SGS and CE standards; Shrinking Ratio: 2:1
  • ❀【Quality Guarantee】- We have a commitment to every buyer 100% satisfaction. Please don't hesitate to contact us Sopoby if you are not satisfied with your purchase. We would try our best to ensure your satisfaction :)
Amazing and easy to use

I have such confidence in the result. I stink at soldering, so much so that I've considered voluntarily surrendering my man card. But these connectors make me seem so much smarter and better than I actually am. The result is secure, water tight, and perfectly conductive. It took a few tries to dial in the heat, but if I stick it right down into the bottom of the lighter flame where it's blue, it works perfectly.

Fantastic product!

To me, these are the best connectors I have ever used for butt splicing wires in an automobile or a marine environment. By heating the heat activated glue along with the heat shrink tubing, the wires will stay in place while you are activating the solder. I'm looking forward to finding these in a spade or eyelet type end in the future..

I will never connect wires with anything else again.

I used these to rewire the radio harness above and they worked fantastic. You can see the results above and they speak for them self. The first pictures was how the harness looked when I pulled it out. Standard electronic twist cable that had come undone and of course sounded like crap. Slip the plastic over one side of the wire, twist the wires together, pull tube over the twist, apply heat gun and you get an awesome waterproof seal. I will not use anything else. I get clean clear music and I know the harness is going to stay together perfectly.

Best idea since sliced bread!

This product makes wiring deceptively simple. The heat gun shrinks to hold then melts the solder, what more can you ask for! The size factor is a huge advantage for tight spaces, the bulkiness of crimp on connectors is eliminated. No more staggered lengths to make things fit. I am a happy camper.

SOLID CONNECTION! Great buy

Extremely easy to use. Makes the best possible soldered connection and the hot melt adhesive completely seals the connection!!! I’ll never solder or crimp a electrical connection ever again! (If I don’t have to) I found these first at my local electronics store but VERY EXPENSIVE, this is a great deal on something that will save you time and money and a lot of headache trying to solder a connection. One tip...use a heat gun not a torch. I did buy a heat gun at Home Depot (Wagner brand) for $20. Works like a champ!!

These solder shrink connectors are the bomb!

These connectors are awesome. This is the second time I purchased them and they come in really handy! I use a small heat gun on these and they are so simple to use for a good secure connector that's much, much better than a standard non solder butt connector. I've used them extensively on both my truck and my camper for adding accessories, etc.

Very convenient with no crimping required

I was looking for a better way to wire up some electric hand warmers for my ATV that I use to plow snow.I didn't want to solder the wires and I hate regular "Butt" splices. I found these here on Amazon and bought them and have used them for a couple low voltage wiring jobs so far and they worked great. I also got a little bit more shrink tube to protect the connections a little better. What a neat invention. Just get a good heat gun and the low temp solder does the job and shrinks over the connection. I will buy more as needed. Very solid termination

Makes for great connections

Used this on my 2012 Traverse where there was a recall on a connection under the passenger seat that was fixed with a crimped connection and that caused me no end of trouble shooting issues and so I finally got these and a new heat gun and ripped out all of the connection that the dealership made and connected with these as a solder connection and the problem completely disappeared.

A great product

I experimented with several of these connectors. I finally ended up with using a hotter, 1500 watt heat gun to get consistent results. The solder melts and the heat shrink tubing doesn't burn. I tried using this with a butane torch but I ended up burning the heat shrink tubing. My first heat gun I had, which was a 300 watt unit shrunk the heat shrink tubing but it took a while before it could melt the solder. The higher power, 1500 watt heat gun gave a quicker, consistent result. I can't even pull the wire apart with my hands. I think this product will pretty much offer good strength against pulls. I can't imagine having that much pressure exerted on joined wires. It would be crazy to use an electrical connection with than much pressure on the wire. I don't see vibration ever loosening this butt connection.

I never want to be without these again!

These things are bad-ass! Really impressed, with one of these and a torch lighter you can repair a wire at least as good as it originally was, maybe even better. The low temp solder melts straight away, the hot glue rings seal the insulation and it's 2:1 shrink factor seals the deal, literally! Very fast, very easy and good -- how often do you see that combo? To test it I took a foot of 18 ga wire, stripped the ends and stuck them into one of these splices, got it all melted and hrunk in about the same time ti takes to position and squeeze a crimper, with the added bonus of being able to see the wire inside of it. Then a friend and I each stuck a screwdriver in the loop, and pulled with both hands against the wire. Try that with a crimp splice! Then I stuck it in a cup of salt water for a week, and left it outside in the sun for another week, not even a hint of oxidation. I get that two weeks is not a thorough test, but it's surely very promising! I never want to be without these again!
