Sopoby Solder Seal Wire Connectors
SPECIFICATION
- Shrinkage ratio 2:1
- Dual-walled design tubing: polyolefin tubing on the outside and hot melt adhesive inside Color coded connector tubing Heat activated waterproof adhesive
- Temperature that start to shrink: 80℃
- Temperature that solder ring start to melt: 111℃
- Temperature that solder ring melt completely：138℃
Note: We suggest the temperature that the hot air gun should set about:400-600℃ (752-1112°F)
- Rugged and puncture resistant.
- Waterproof.
- Resistant to abrasion, stretch and vibration
- Heat activated adhesive
- Greater tensile strength
- All materials are heat resistant
- Suggest used a 1500W heat gun.
- Create a waterproof seal
- Resistant to stretch and vibration
- Color coded for easy identification
- Starts to melt at lower temperature (280 °F)
- Prevents burns in the heat shrink tubing
- A more efficient alternative to soldering
- Offer protection to the wires and cables from abrasion, cutting, scuffing and low impact situations.
- Create cable entry seals, offering environmental sealing protection.
Strip wire insulator with a proper length and insert wires into the solder sleeve of proper size
Twist the conductor together and move the connector to the middle of the conductor
Evenly heat by a heat gun (better with reflector nozzle) until it melts

Was skeptical at first, considering the grote solder seal connectors cost atleast 10 times as much. But I was happy with them, work just as good as Grote. I've used a couple dozen now, not a single problem yet.

These are technically an off brand, but I couldn't justify the extra money on the name brand originals. I got one of the 100 piece ones when adding various lights to an ATV, and will never use a regular butt connector again if I can avoid it. The solder melts well, they are reasonably thick, the clear heat shrink waterproofs well and let's you see when the solder gets into the wires.If your putting anything together that even theoretically might get wet, just get these over regular butt connectors they are so very nice to use.Disclaimer: I have a little pen-shape butane torch/heat gun that I use, but a torch or lighter should work as long as you don't get the heat shrink too hot, as it will eventually burn. It does melt the solder well before it burns the tube though in my experience.

I've always shied away from using but connectors and other crimp on style connectors except for temporary usage. I have always soldered and shrink tubed my connections and have never had an issue. I heard so much hype about these connecters that I finally gave them a try. To my surprise, they are just as good as soldering and shrink tubing the connections but with fewer steps. A real time saver and a good solid connection protected from the elements.

Aun con pistola de calor al maximo la soldadura no se derritió. Solo el plastico se encogió, nada mas.

As an Engineer I found this to be a great idea so I tested it out on a piece of wire which I stripped and twisted together. I slid one of the red shrink sleeves over the joint then used a lighter, and after a few seconds of moving the flame back and forth, the solder seemed to melt and it looked to be a good connection. Then I tried pulling it apart and the connection failed.I then tried again, but this time I dipped the stripped ends of the wire in Flux which is a very necessary part of the soldering process. Not only did the joint work perfectly after using the flux, it also heated up much faster, reducing the chance of melting the plastic. Without the flux you can get what is called a "cold" joint where the solder melts but doesn't really flow onto the wire.I don't know if the average person has flux laying around but it would be great if they included a small tube in the kit. Or better yet, figure out a way to line the inner part of the shrink tube on either side of the solder, so it gets applied to the wire when things heat up.Great idea and works in a pinch when you don't have electricity for a soldering iron - just needs flux!

*EDIT 5/1/2020* So I'm positive these are the best things in the world. I've finally exhausted the majority of the 50 pack and just gladly ordered the 280 and can say that 20-25 for these things is a great deal for how effective these are. For super permanent or less space-starved fixes I still prefer to sit down and solder/wrap normally (like wiring a car stereo) but for just about anything else, even stuff you might come back to, these are a game-changer. You can hold more heat shrink onto the back of the wires since it takes way less heat through the wire to secure these than actual solder where the wire itself can get pretty hot, especially larger more conductive wires that might start closing the heat shrink down the wire prematurely while securing the joint.This actually saved my butt when my headlight wire got caught leaving work (I get off after dark). I had thrown a few in my backpack "just in case" and it actually came up. These are super convenient and get the job done. They're actually pretty solid, too, and feel relatively trustworthy.I like these better than the hard, plastic crimps that don't shrink down, obv, but I mean these things are definitely more solid, and I feel like I've gotten those things tight. For anything worth anything that needs to be permanent, you want to splice, solder, and heat shrink. But when that isn't an option anytime soon, these are by far the most clutch tool to have in your electrical toolbox.

I read a bunch of the reviews and took a chance that this lived up to the hype and it really does. It was super easy to join all the wires in the cable harness that I was working with. I was easily able to push the one wire through and then the other from the other side, have them mingle in the center and then hold it over my upright heat gun and just watch the heat shrink tubing and then the solder seal up the joint. It was beautiful and made a strong and water tight seal (not that water tight was really anything I needed to worry about), just like a regular soldered joint and heat shrink, but without a two step process. The only thing I needed to be careful of is that the whole thing is still a bit gooey when you take it away from the heat gun, so letting it cool a few seconds before applying any accidental lateral pressure kept from making a mess. Connected about 30 pairs of wires in about 30 minutes without having my hand hurting from crimping connectors over and over again. Love this, would totally order it again, and as some others mentioned, the box was surprising small and compact. Really great, highly recommend, but you definitely want to have a heat gun.

Great quality and nice variety of sizes. I bought these to have them on hand for when I need them which when you are living and travelling full time in a 5th wheel is pretty much anytime something stops working it seems everything is somehow tied to electrical in one of these and because it's like a earthquake in the trailer every time you move it things break and come loose fairly often. I've used several of these already and love having them onboard because every time I've used one the outcome has been perfect the melt exactly like they should using my 1500 watt hot air gun all you have to do is strip and short piece of each wire end your using first insert one wire end into the splice and melt the splice onto the wire, insert the other wire end into the open end of the splice and again melt the splice with a hot air gun or other heat source the metal center of the splice will complete the circuit making the wire whole again that's it it's not hard at all. I've had great success with these in the trailer and in my pickup I use to tow the 5th wheel I don't see running out of these anytime soon but when and if I do I will be buying more just like these from this seller.
