Best Ring Terminals of 2025

"I was really pleased that these connectors were as robust as they appeared. After crimping, they were rock solid—exactly what I needed!"

"This kit provided an excellent value and was just right for my project."

"While these connectors will work, I found them to be a bit thin. The smaller sizes are fine, but the larger ones could be thicker for my preference, which is why I gave it a four-star rating."

“As someone who fixes appliances, I was tired of using cheap connectors from local hardware stores. These connectors are competitively priced and have much better quality. The shrinkage is perfect! I'm confident they are more durable and plan to stock up in the future.”

“I purchased the HAISSTRONICA 260PCS Marine Grade Heat Shrink Ring Connectors, and I'm impressed with the quality and ease of use. The connectors are exceptionally well-made, providing a reliable connection. The installation is straightforward, and the heat shrink tubing creates a tight seal. The assortment of sizes is very convenient, and they hold up well in tough conditions.”

“This little kit has proven to be handy many times. I appreciate the organization of the connectors, and they seem to be of fairly good quality. I've had no complaints at all. I would definitely buy them again.”

"I found these connectors to be high quality and they worked very well. The added shrinkwrap insulation was a nice bonus for my DC applications."

"In my experience, they are of good quality and function perfectly for making rings on wires. Plus, the price is great for the quantity I received."

"Using a low watt heat gun, I could easily shrink them. They are of good quality, and I would definitely order again."

"These quick connectors were exactly what I needed to finish my electrical work. They made everything much easier for me, and I believe they offer great value for the price. If you don’t have these in your toolbox, I wouldn’t hesitate to get them—they're worth it!"

"I think these crimps are mostly good, but they can be a bit hit-or-miss. I've noticed that about 1 in 5 crimps didn’t hold well during my tests. However, I found that if I strip the wire longer than needed, fold it over, and twist it tightly, it holds really well when crimped. For those experienced in wiring, this should work fine, but it might be challenging for beginners."

"I restored part of my car harness using these ring terminals, and they performed as I expected. They are easy to crimp, and the wire stays in place even with a lot of pulling. I'm definitely planning to buy more soon!"

"I find these connectors to be just as good as any other marine grade options I've used, but at a better price. When doing boat wiring, I've learned the importance of using the right crimpers to avoid damaging the heat shrink. I often add extra marine grade heat shrink tubing over connections for added protection. I just want to help others avoid wasting money by using the wrong tools!"

"These connectors were exactly as described and performed their job well. The heat shrink worked effectively, sealing around the wire. My only minor issue was with the messy box; the different sizes were a bit mixed up."

"I’m very pleased with this purchase. They are easy to use and function perfectly. However, I did wish the eyelet was slightly thicker, but overall it's a great product."

"I really like this set of heat shrink terminals. The three different colors are a nice touch!"

"I primarily needed one size, but now I have a lifetime supply. The quality is quite good."

"I do a lot of marine electronics work, and these heat-sealed connectors are essential around saltwater. After trying several brands, I find these terminals to be as well-constructed as any I've used."

"I find them not too cheap feeling. The crimp holds strong and makes a good connection. I have no complaints."

"These are sturdy, rigid, and thick enough to hold a solid crimp and carry rated current. I would definitely buy these again."

"They look and work identical to what I had. All 100 fit perfectly in their cubby hole in my tray. I think 50 would have sufficed, so I'm set for a while now."

"They work just right; I would buy more when I run out."

"Molex quality is unmatched. Great crimp every time and they’re nice and thick!"

"I needed high-quality terminals for a critical job. These are nice and thick, holding their shape well."

"This set is just perfect! Now I can choose the right size ring terminal without any hassle."

"I recently purchased the 10pcs 2/0 AWG-3/8" Wire Lugs along with the 3:1 Dual Wall Adhesive Heat Shrink set, and I’m thoroughly impressed! The lugs are exceptionally well-made with heavy-duty materials, ensuring excellent conductivity. The installation process was straightforward, and the heat shrink tubes provided a superior insulation seal. I highly recommend this set for any electrical wiring projects!"

"I went with this seller because they were the cheapest, expecting a middle-of-the-road product. To my surprise, the lugs were exactly what they claimed to be! They crimped well, and the heat shrink tubing performed excellently. This product exceeded my expectations, and I will definitely return when I need more pure copper lugs!"

"The TKDMR 1/0 AWG-3/8 Battery Lugs were perfect for my car audio and battery wiring project. These heavy-duty lugs feel high-quality, and the crimping process was smooth. The included heat shrink tubing provided a clean, professional finish. I’ll certainly be buying more for future projects!"

"I didn't read the product description carefully, my fault, not the seller's. I was hoping for some 3/8 inch rings, but the largest is just shy of that. Good quality, and I will find uses for them all."

"I received brass terminals, not copper as stated. The label on the box confirms they are brass. I prefer the softer copper terminals, but these will work fine in low vibration environments."

"I do a lot of electrical repair on various vehicles. If I had noticed how cheap these were, I wouldn't have spent my money. They will likely do the job, but they are thin metal. There's a chance that when I crimp the wires, the connections might not stay tight on vibrating equipment."
