Wirefy Solder Seal Wire Connectors Kit - Heat Shrink Wire Connectors Kit - Waterproof Solder Sleeves - Self Soldering Wire Connectors - Set 26-10 AWG | Wire Butt Connectors Heat Shrink 110 PCS

Working as advertised! Using for hobby stuff. They shrink and melt very nicely with my dinky 300W heat gun/pen. Just gently turn and move the wire up and down and it all melts into place. The solder *does* melt last, so keeping things slowly moving is important to not just burn off the wrap before the inside stuff melts. Eventually though, the goo, the solder, and the shrink wrap all slurp into place like they're supposed to. Nice, snug connection too. Wouldn't use these in very hot environments like next to an engine block. (Hear me out: Solder melts!) Otherwise, great stuff. I'll say again: You can't just concentrate heat on the solder for this to work. Gently turning the heat gun or connection while slowly moving up and down the joint, the solder does melt. It takes longer than the rest. I'm sure if you just park your gun on the solder it'll melt the wrap before the solder gets enough heat to give. By the time it does, the rest will have molded firmly into place, too. This worked perfectly for me even with the smallest connector. It's like making Rice Krispies: You gotta use lower heat and a little time or they'll come out all hard and crispy. And if ya do it right, it's like magic! Where have these been all my life?

I recently purchased the Wirefy 100 PCS Solder Seal Wire Connectors, specifically designed for 12-10 AWG wires, and my experience has been overwhelmingly positive. Here’s a detailed review based on my usage: Ease of Use: These solder seal wire connectors are a game-changer for anyone looking for a reliable, no-fuss solution in electrical wiring projects. The self-soldering feature simplifies the process significantly. Once heat is applied, the solder melts and securely bonds the wires together, while the outer sleeve shrinks to protect the connection. This dual-action ensures a durable and waterproof seal, which is crucial for any wiring that might be exposed to moisture. Performance: The connectors performed exceptionally well in my tests, providing a strong, conductive connection without any need for crimping tools or additional solder. The solder in the connectors melts evenly, and the heat shrink seals thoroughly, leaving no gaps for potential water ingress. This is particularly important for outdoor or automotive applications where exposure to elements is a concern. Durability: What impressed me most was the durability of the seal. The connectors are designed to withstand harsh environments, and once sealed, they are both waterproof and heat resistant. This durability is vital for ensuring long-term reliability and safety in your wiring projects. Application Technique: For optimal results, it is crucial to use a heat gun with an adjustable temperature setting. I found setting the heat gun to approximately 550 degrees Fahrenheit works best. It allows the solder to melt effectively without overheating the connector. Start by heating the outer sleeve to secure the wire in place, and then focus on melting the solder for a uniform and secure electrical connection. Value: Considering the quality and the quantity provided in the package, these Wirefy solder seal wire connectors offer excellent value for money. They save time and potential costs from manual soldering errors, making them a cost-effective solution for both professional electricians and DIY enthusiasts. Final Thoughts: The Wirefy 100 PCS Solder Seal Wire Connectors are an excellent choice for anyone in need of efficient, reliable, and easy-to-use wire connections. They make projects quicker and simpler while ensuring that connections are secure and durable. Whether you are working on simple home repairs or complex automotive wiring, these connectors are designed to provide a foolproof solution that stands the test of time. Highly recommended for their superior performance and ease of use. If you are looking for dependable wire connectors that promise professional results, look no further than this set from Wirefy.

Works well. The solder doesn’t stick to the wires as well as I would like but if you fold the ends of the wires over before inserting them into the fitting they work much better. Kind of hard to deal with in tight areas when doing repairs and while the solder is melting the plastic gets very soft and it is easy to tear. Just have to hold it still until the solder cools and hardens.

Read lots of reviews on this item where buyer stated it burns while applying or solder taking too long to melt and work properly, not the case for me. What works for me is using a mini butane torch and rotating the connector while applying heat, start from the solder area and work your way towards the ends of the tubing consistently back and forth; it worked flawlessly. Apply too much heat and you'll have a "bad" experience. The blue water seal works great, and the adhesive on the tubing melts just fine to create a water proof seal. It forms a strong bond

I've been using crimp butt connectors for years and then having to seal the ends with liquid electric tape, or before that wrapping with electrical tape. Who ever invented these deserves a BIG hug. The previous negative reviews for this particular company obviously didnt know what they were doing. The first attempt with these, using a heat gun as instructed worked perfect. I used the low setting on the gun at first and then kicked it up to high to melt the solder just for a short quick period and turn it off. Make sue to rotate the heat gun on the solder joint. Great product !!!!!!!!!!!!!!!

Work good

These things are pretty cool. A great idea that makes soldered splicing much easier. I used them by sliding first a piece of marine-grade adhesive lined heat shrink, and then one of these over one of two pre-stripped wires, and then twisting the wires together tightly (as close to a lineman splice as you can get) before sliding the connector back over the splice and using a torch to first shrink the heat-shrink material and then add a tiny bit of extra heat to the solder. Once you see it run, back off. That's the only issue I have with the materials is that the heat shrink will melt if you're not careful. But they still get five stars because to me that's a small price to pay for a product that works like this one. Then slide the marine grade shrink down and use the torch to shrink it up. The only thing I'd like is for them to sell them in quantities by size rather than this assortment. I work with 14, 12, and 10 gauge wire pretty much exclusively and have no use for the smaller sizes.

I did a test run on a new piece of 16 ga wire. Even intertwined the strands on the junction to help the solder have more surface area to contact and seal. I used a butane mini torch with a heat deflector shield that I've used many times on heat shrink tubing and it always works flawlessly on that. Took extra care to make sure that I got even heat all along the length and around the diameter of the connector and tried to focus on getting the solder area evenly heated with the "right" amount of heat so that solder would melt, but outside sheath would not. I let it sit overnight and went out the next day to see if the solder connection held. Unfortunately, it took little effort to pull the connection apart. I don't think it was near as much as would be required to pull apart a crimped butt connector. Since I wanted to use these on trailer axle brake wire splices, I needed the connection to be able to hold up to the possibility of minor road debris hitting the wires. In the end, I resorted to doing a traditional solder junction, then sliding these over that and heat shrinking them to make it moisture resistant. The first one shrunk down well and looked to be quite water resistant. Unfortunately, something about the second one caused a mini blowout of the connector around the solder joint and I had to use another method to make it water resistant. It may have been some residual soldering paste or the two incompatible types of solder that caused the reaction and subsequent blowout, but in any event, it wasn't what I had hoped for. If you need to use this in a somewhat rugged duty situation, I recommend to just take the time to do a solder joint and seal it with heat shrink tubing.
