Review: legendary product - You can buy it with peace of mind of very good quality. Seller ships fast thanks seller
Review: I've never used this type of wire connector before, but I connected wires with four of them without any issues. they work as expected. I also bought this heat gun, B0CHVDL25P, because of another review suggesting using a reflector, which I didnt have. My only negative opinion of them is wishing they had more solder or some type of indicator when the joint is secure because I was unable to see the solder melt and just guessed when it was complete.

## Questions & Answers

**Q: Do you offer larger than 250 count sets?**
A: Yes

**Q: Is it possible to make a 3-way connection with these?**
A: It is possible, yes, but it’s a little tricky. Two of the wires end up being twisted together and inserted into one side and the third wire ends up on the other side. You’ll likely have to use the next size up to accommodate the double strand. I’d recommend adding heat shrink to the side with the single wire, as it may not seal as well as the other side, since it’s stepped up. The connections I made this way have been in service on my car for more than two years without any issue.

**Q: Do these connectors work on 14 awg solid copper wire (in 14/2 waterproof cable) laid underwater to a small island (110 vac)?**
A: Hi friend, we are so sorry to tell you that these solder connectors are not suitable for solid copper wire. Actually they are designed for stranded wire. We recommend you to use heat shrink crimp butt connectors. It woule be safer for your projects after the solid copper wire being crimped and heat shrinking. If you have any additional questions, just contact us seller. We will do our best to assist you. Thank you!

**Q: Can this be used with AC electrical?**
A: It can be used with any wire. You have to find the size that you need. My husband used it on a beacon light that goes on top of your vehicle and it works really good.

I have used several of these connectors for different projects, including adding accessories to my RZR and fixing various appliances around the house. One of the standout features of this kit is its ease of use. The solder seal connectors create a strong, waterproof bond without the need for complicated crimping tools, making my work faster and more efficient. These connectors provide a secure connection that holds up well, even in tough conditions. I was particularly impressed with how well they performed when used on my RZR, where they faced exposure to vibrations, dirt, and moisture—yet the connections remained intact and reliable. For appliance repairs, the heat shrink design ensures a tight, insulated seal that has given me peace of mind knowing that the electrical work is protected. Overall, this kit has proven to be an invaluable addition to my toolkit. Whether for automotive, marine, or household electrical projects, these connectors have consistently delivered quality results. If you need dependable, high-quality wire terminals that are waterproof and easy to use, I highly recommend giving this product a try.
