10pcs 1/0 Gauge 1/0 AWG x 3/8” Pure Copper Cable Lug Terminal Ring Connectors with Dual Wall Adhesive Lined Red + Black Heat Shrink Tubing – by WNI

The quality of the connector is good, but the 2/0 gauge connectors I ordered are barely big enough to fit the 1/0 gauge wire I have. This will not work for 2/0 gauge wire! I thought my first order was just a small mistake, so I returned them and tried to order again, but both times the 2/0 gauge connectors are just way too small. I cannot speak for the other size connectors. I'm just going to keep these and possibly use them in the future or give them to a friend. My local shop has true 2/0 connectors but they just cost so much more, anyways, I will go to my local shop.

I am using these to make flexible ground straps used between some equipment and a common ground. They are of good quality, they crimp easily with my hand crimping tool (although it is fairly robust), and the pure copper solders well for an extra secure and conductive connection. The heat shrink tubing that is included is a big plus since I don't have anything that large in my usual inventory. A full five-star rating for the product and the supplier.

They're copper. They're the right size (1/0). They crimp. Not sure how much more to write about these, but I have been happy with how they are to work with. I had to make 10 cables today, and probably another 6 tomorrow, and so far only one crimp wasn't perfect, and that was my fault (so I re-crimped a second spot slightly removed from the first and now it's perfect).I didn't expect anything from the shrink wrap, since it looked like a freebie gimmick, but it's actually pretty good shrink wrap. Probably not marine grade, but other than that, very good.

The lugs fit my 1/0 gauge wire perfectly. However, the heat shrink they sent is massive - more likely sized for 4/0. It doesn't come close to gripping either the lug nor my cable (and yes, I used a proper heat gun to shrink it). I have some of my own properly sized heat shrink, but since I've already crimped the lugs on - I have to cut one end off to add the heat shrink. Which means, a wasted lug (which isn't cheap), and in some cases a waste cable because I had sized them precisely for my needs.Just seems like poor quality control - and now wasted money because of such a small mis-step on the seller's part.

These lugs are pure copper for the best in connection and conductivity. They are well made, heavy duty, and the copper is thick and very durable. My 2/0 AWG cable fit perfectly and crimped great creating a fantastic cold weld.The included heat shrink was tossed in the trash can right away. Way too thin, and these will not provide any protection. I used my own high quality heat shrink for a durable and well protected connector.I find these lugs to be very high quality with very cheap heat shrink. They are a good value for the price, just use your own heat shrink or order some and forget these. I give them 4 stars.

Lol, no way these are going to fit my 1/0 AWG wires. They fit 4g AWG. And the heat shrink they sent doesnt even match the lugs. They sent me four 4 inch pieces of true 1/0 heat shrink. Isnt even cut into 10 pieces like the image shows when you order. Very misleading. No way you can get 10 pieaces out of what they send. Never again!

You will need a crimping tool to install these, but if you are buying them you probably already own one. They were very simple to use. I was able to build a battery bank using these, a set of marine terminals, and a set of “donor” jumper cables. It cost me a lot less than buying bridge wires pre built. The shrink tube worked nice and adds a nice touch.

Bought a 10 pack of 2/0 gauge ring terminals and when the package arrived it said "2/0 gauge 2 awg". 2 awg is not the same as 2/0 and is actually smaller than 0 gauge. The whole point of me buying these was so I can use wire bigger than 0 gauge for my sound system. Will be returning these asap!

All is good and as described

fit my 6 gauge wire perfectaly
