Best Ring Terminals in 2020



E-VOLT 80 PC Yellow Heat Shrink Ring Crimp Connectors: Sizes: #10, 1/4", 5/16", 3/8". Gauge 12 10 Bulk Electrical Terminals - Insulated 12-10 AWG Automotive, Marine, Audio, Industrial Review:


My expectations for these lugs were high, and they were met. The lugs themselves are substantial, and the heat shrinkable sleeves work well in reinforcing the connection mechanically, as well as seal with the adhesive lining. They're a little more expensive than standard lugs, but are better in every way. Even the tongue has a wider ring than some standard lugs. I use these in automotive applications, and don't think twice about putting them where I'd never use a standard lug.



Mofeez Bus Bar -3x1/4”Post,10x#8 Screw Terminal Power Distribution Block with Ring Terminals(Pair - Red & Black) Review:


Overall I like this bus bar, it seems hard to mess up a price of metal with screws in it after all, however there are some key things that make it worth buying and a few things I would change if I had the option.

Pros-
The stagering of screws and spacing makes it simple to get multiple terminals in place solidly.

The cutouts on the sides are a good size for even my larger terminals, however I do not feel at risk of shorting something or dropping something in the bar.

The main poles have a nut on top and bottom that spaces the terminal more to the center of the opening, this means the offset terminals will fit in either direction.

The plastic feels of good quality and seems to be as durable as I would need it to be.

Cons-

I would love to see more of a flanged nut for the main poles, just something to provide more electrical contact to the ring terminals. Maybe even just some included copper washers between the nuts for the lock washer to press against rather than the terminal itself.

I would love to have the option of only one side having openings in the cover. For horizontal mounting with connections coming out the bottom. Maybe some sort of perforated knockouts? But not if this would mess of the quality of the cover, just in an ideal world.

Overall I like the product, I also like to nitpick and dream...



SELTERM UL Listed Heavy Duty Wire Lugs Battery Cable Ends Bare Copper Eyelets Tubular Ring Terminal Connectors Review:


If you're looking at these for car audio, 0 gauge 5145 strand ofc wire, THAT IS AN OVERSIZE WIRE! You need these 2/0 guage terminal lugs to fit that wire. I wish someone would have told me this, i had to figure it out for myself.
THESE ARE ABSOLUTELY PERFECT for car audio applications offset foot pad allows it to lay down flat. And if you got more than one going to a bolt and there's room you can put the foot cats back to back and they still lay down flat on each other. HIGHLY RECOMEND the adhesive lined shrink tube to use with this also HIGHLY RECOMEND getting using the hydraulic crimper not a hammer crimper. The hydraulic crimper makes you crimp look clean and professional. I got the 16 ton. The $50 i spent on that crimper was money well spent because of how easy it is to use and how much crimping force it exerts on the lugs. And when you're done with your project you can rent it out to your friends and get your money back!



SELTERM UL Listed Marine Grade Tinned Copper Wire Lugs Heavy Duty Battery Cable Ends Eyelets Ring Terminal Connectors Review:


I'm up to my ears in a boat rewiring project. I needed a number of battery/power cables of specific lengths, and was growing increasingly horrified by how much custom cables actually cost. So I decided to make my own custom cables - I got some 4GA cable, assorted appropriately-sized crimps (these parts), and a crimper/cutter tool combination, and then got busy.

In the end, I was able to make a half-dozen custom-length cables for about half the cost of "professionally made" versions. It helped that I was a professional cable/harness maker in a previous life - I do know what I'm doing here. I'm also an engineer by training and profession, as well as a big MacGuyver fan - I take some small amount of pride in being able to get the job done, no matter what it is.

There is certainly a trick to getting good big-cable crimps from inexpensive tools and parts, but it CAN be done. It just takes practice, patience, and a learning curve.



270 PCS Heat Shrink Wire Connector Kit Electrical Insulated Crimp Marine Automotive Terminals Set Review:


These connectors did work for me, but I ran into a few problems. This is coming from a weekend warrior; not a electrical veteran.

First, and this isn't necessarily a problem with the product, but important for customers to know: a hair dryer will not work; period. We have a very high temperature, high power one here that I thought would work with some patience; it didn't make a dent. I had to order a heat gun and use it on a high settings to even begin shrinkage. So factor that into your cost analysis.

Second, I assumed electrical connectors were standard sizes, and that I could trust the measurements given. Unfortunately, none of the yellow connectors fit into my PSU's terminals except the male spades, and there wasn't nearly enough room for the terminal screw to go through that (since that's not really what they're for). In the end I didn't use the connectors, I attached the bare wire, which made my purchase of these pointless. I measured the size of my PSU's terminals at 3/8" and this kit includes 1/4" connectors, but that's an internal diameter; this may be standard, but I wish the description had included something about this for beginners.

But here is my big complaint: the wire sizes are wrong. I tried to use a blue butt connector to connect an 18 awg wire to a 22 awg wire. They didn't fit. I had to use a yellow to attach them. And I couldn't fit my 10 awg wire into the yellow butt joint at all. This caused a serious problem for me and set me back quite a bit.

However, the connectors held well once installed and the heat shrink worked as expected. The heat shrink material seemed sturdy and I had no problems with tearing. In the end I was able to get the job done (although without connectors for my PSU.



InstallGear 4 AWG Gauge Gold Ring Set Screw Battery Ring Terminals (4 Pack) Review:


Beware the insulating clear coat! I have purchased a number of these because they are nicely made of solid brass and (apparently) gold plated. But the problem I discovered is that there was then a tough clear coat plastic finish that was applied on top of that - which acts as an electrical insulator. I discovered this accidentally when I made a battery cable using these. I bolted one end onto the negative terminal, and then accidentally dropped the other end - and it hit and bounced off the positive terminal. Not good. However - there was no spark - at all! Knowing this was not right - as this was a new, fully charged battery - pulled out my ohm meter and checked - there was zero connectivity when I just touched the lead ends to each end of the cable on these terminals. Suspecting that an insulating clear coat had been applied I then scraped and dug down the sharp ohm meter leads into these terminal ends, and finally got connectivity once I had metal contact.

So beware! These look great, they are nicely made, they firmly fasten the battery cable into the end using the large set screw, and they are reusable - but as shipped the clear coat provides an excellent electrical insulation - which must be cleaned off if you want to achieve a good electrical connection. I tested all the other of these terminals which I bought - all built the same way. So what I did to fix this was -
- lightly wet sand using 320 wet-dry paper on a flat block - just the 2 flat terminal sides. Just enough to begin to scratch through the clear coat there.
- Then - using a Q-tip - I applied some Goof-Off and scrubbed that for a while. This is a tough paint-remover, and I could see it slowly dissolve and remove the clear coat there - though it took some scrubbing..
- I did this on both sides of the terminal flat sides until I could see that all clear coat had been removed.
Now - when I barely touch my ohm meter leads on the cleaned sides I have great connectivity.
I then lightly coated those areas with GB OX-800 Ox-Gard Anti-Oxident Electrical grease to prevent any corrosion of the exposed brass.

SO - these are well made but if you want a good electrical connection (which is part of the reason I got these) you MUST clean off the insulating clear coat before use!!

Heat Shrink Connectors - 270 PCS Insulated Electrical Crimp Heat Shrink Wire Connectors, Marine Automotive Copper Butt/Ring/Hook/Fork/Spade Disconnect Terminals Kits, CE SGS ISO Approved. Review:


I started using heat-shrink crimp connectors for automotive applications a while back, now I use them for everything. I had been using connectors with a 2:1 shrink ratio, so I was looking forward to trying these with a 3:1 ratio.
First, the connectors themselves - they are tinned copper, they take a crimp well with any reasonable crimp tool (I used the cheapest one on my bench just to try them out). 10ga stranded silicone-jacketed wire was a very snug fit in the yellow connectors, it took a little concentration to assemble those. 12ga was a breeze. I also did a test crimp on some 18ga TXL automotive wire using the red connectors. The important thing is, check your crimps - give each wire a tug before you declare it a good crimp and move on to the heat gun.
The heat shrink sleeves are where these shine. The yellow connectors, especially, have some seriously thick heat shrink. It takes a LOT of heat to shrink these, this is not hair-dryer territory -- you will need a proper heat gun. I use yards and yards of thin-wall heat shrink to dress automotive wiring, I can just pass the heat gun over that and shrink it. No so with these connectors, the yellow took some concentrated heat (the smaller red connectors took significantly less). The best part is, once shrunk it provides a tough combination of sealing and strain relief. I'm hooked.



Maxdot UL Heavy Duty Wire Lugs, Tubular Ring Terminals Connectors Battery Cable Ends, Bare Copper Eyelets with Heat Shrink Black, Red Review:


I have purchased a few different brands and they all ended up being pretty cheap. If you are looking for nice thick copper connectors, then these should do the trick. They crimp just fine and provide a solid connection. seller equipped with them some adhesive shrink tubing, and you'll have a connection that will last.
These lugs are quite well made. I crimped them onto welding cable used for interconnects for my solar battery system. I use a simple die crimper that uses a few hammer blows to make the connection. Be sure that you are not shy about getting the lug properly around the cable.



Glarks 65Pcs Assorted Heavy Duty Wire Lugs Battery Cable Tinned Copper Eyelets Tubular SC Ring Terminals Connectors with Spy Hole Assortment Kit Review:


Good assortment. Great value for money especially when compared to the ripoff auto part stores. Terminals are acceptably sturdy. I was using with #6 stranded copper battery cable. I just put the wire in and crimped it with a hammer. Don't need a special crimping tool (You can add a line crimp with a pair of side cutters after the hammer treatment).
