Best Butt Terminals of 2025

"I found these connectors after watching a YouTube video, and they worked perfectly for wiring up a temp sensor on my son's car. Using a heat gun was ideal since I needed to avoid any accidental melting. Overall, I'm really pleased and will definitely buy more!"

"I recently tried the Heat Shrink Solder Seal Wire Connectors and was genuinely impressed! The combination of heat shrink and solder makes wiring so much easier. After heating, the solder melts to create a solid bond, ensuring everything stays securely connected. This has really transformed my electrical work!"

"These connectors are fantastic! They made taking out the connecting plugs in my Christmas lights a breeze. With just a wire stripper and heat gun, the solder melted quickly, providing a strong connection. I even added extra shrink tubing for peace of mind, and the value for the number of connectors is great!"

"I appreciate the good shrink ratio and they allow for slight movement until fully cooled. Once cooled, they become very hard. I’ve tried many brands, but these are my go-to for repairs now."

"These connectors are just like what I find at autoparts stores, but at a more than fair price. You might find it funny, but I'm even thinking about buying more as Christmas presents!"

"Initially, I was a bit skeptical about the quality due to the price. However, after using these, I found that the plastic is tough and shrinks well. The metal crimp is strong, and I’ve had good results with both a torch and heat gun for shrinking, though the heat gun is definitely the better option. Overall, a super value!"

"I've had great luck with these crimping well, and the heat shrink seems to create a decent seal."

"I purchased this kit for my utility trailer lights, and I had no issues installing them. Using a barbeque lighter to shrink the tubing worked perfectly, and it drew down tight after just a few passes. A great price with several sizes!"

"I've used these for fixing my truck's trailer hitch and connecting sprinkler valves. They're easy to install and seal up really well, making them very reliable for my projects."

"After being skeptical, I was surprised by the effectiveness of these connectors. Using them requires a good heat gun and patience, but they create a strong joint that's better than crimp connectors. In tough conditions, these will be my go-to choice."

"The TICONN 100 Pcs Solder Seal Wire Connectors have transformed how I handle electrical connections. They're easy to use and provide a professional-grade connection every time. The waterproof feature is perfect for outdoor projects."

"It was my first time using these connectors for a car stereo project. I found them to be quick and easy, but I had to be careful with the solder. They work well for lower voltage connections, although I’d be cautious about using them for heavy loads."

"I've found the quality to be wonderful, and they do their job perfectly. I recommend using an extra heat shrink for added security."

"These work great for connecting my cables. The heat shrink performs well, and I would definitely order them again."

"I was excited to try these for our strobe lights, but unfortunately, the wires didn't hold tight enough when crimped, which was disappointing."

"I found these easy to use with my crimpers and they hold strong."

"These connectors crimp well and have good holding power. For the price, they're a great deal."

"I tried a few test wires, but sadly, the wire remained loose despite my efforts. I decided to throw away the batch and will continue welding until I find a reliable product."

"I’ve utilized many of these connectors for my automotive projects. The heat shrink material works great, and I achieve consistent results with my wiring looms. I don’t have a top-notch crimper, so I occasionally need to crimp a few times for the best connection, but I believe this isn’t a fault of the connectors. Great affordable kit for hobbyists or small businesses, highly recommend!"

"I just received these connectors and got right to work. They offer three different sizes, which I needed, and they’re easy to crimp and shrink. I highly recommend this product and plan to buy again!"

"These connectors perform exceptionally well and provide great value for the quantity in the kit. My only minor complaint is that sometimes the metal crush sleeve wants to slide out of the heat shrink when I use the connector tool. Overall, they work very well, and I would definitely recommend them."

"This kit has an excellent variety of wiring sizes that are essential for boat repairs and installations. As a former professional at a busy boat yard, I've used countless connectors, and I needed these for my trailer light wiring, which demands durable and water-tight connections. The shrink fits perfectly, and the adhesive flows out completely around the wire, which is exactly what I need. Plus, the plastic holder is a nice addition since I lost my previous kit."

"While there's not much to say about these connectors, my only wish is that there were more lower gauge connectors included in the kit."

"I'm really pleased with my choice to buy the multipack. I initially thought I only needed a few connectors, but I ended up using many more for different projects!"

"It's fantastic to have all sizes available. The product is of good quality and easy to use. I utilized it for car wiring, and it shrunk perfectly with some heat."

"I appreciate that these are crimp connectors that shrink tightly when heated, making them waterproof. The quality and price are fantastic."

"I've found these to be of good quality and value, plus they're easy to crimp."

"For wiring our flatbed, these connectors worked great and the price was excellent!"

"I'm very pleased with these uninsulated butt connectors. They feel high quality, with thick walls and tapered ends for easier wire insertion. The price is excellent for the quality. I recommend using good quality crimpers for the best connection. After a single crimp, I couldn't pull the wires apart. If you want reliable connectors that create strong, lasting connections, these are a great choice. I'll definitely purchase these again!"

"I really like these connectors. They are great quality and come at a good price. After trying them, I found they hold well. I initially had a small issue with an 8 gauge wire, but it was probably my fault. Overall, they do what they're meant to do, and if you need smaller sizes, this is an excellent deal!"

"From my professional perspective, this item is easy to install with the right tools. The main advantage is functionality, as these connectors protect copper electrical conductors in connections that only have screws. They eliminate the risk of damage without deforming or cutting the wires during tightening."
