Tnisesm 525 Pcs U Shape Copper Ring Terminals Crimp Kits - Non-Insulated Assortment Cable Wire Spade Electric Butt Connector Kit Tn-02-3

As long as you have the right crimping too, these are so nice! The connections are secure, crimp on a moving vehicle every time, never solder! This is the crimper I use - https://a.co/d/csDI6JY.

These may never be used the first time, but I have them, they were shipped with care and timely enough and the cost to have them if ever needed was definitely a decent price . You typically could split this set with a couple buddies and everybody could have some on hand . I'm 60 and someone will inherit mine I'm certain.

these are great if you have the correct crimping tool. the 'U' shaped ones im not so sure, but the longer ones in this kit are excellent butt splice connectors.

They do work, but not as well as other brands I've tried. The shrink tube is too big and the crimp terminals are spread open too wide to fit in the tool. I use regular pliers to squeeze the terminals closed a little bit so they will fit in my crimping tool.

I use these by the hundreds for wire to wire connections. I cut, crimp, solder, heat shrink finish with a split loom cover. As with any crimp style connector, it's very important to have the best crimper money can buy. Most connector manufacturers recommend a particular crimper and yes they're pricey, but, that's the one to get. Saves a whole lot of aggravation!

I’ve been looking for these for a long time. I used to work for BMW and their crimps are exactly like the ones on the left. They’re about a dollar each from the dealer if you can believe that. I’ve been searching for years for a supplier of these and was ecstatic when I found these. I do a lot of wiring and like I said I’m happy these are avail at a way cheaper margin that the dealer and the same exact thing. Super easy to use with the right crimper and the size I needed.

Like another reviewer said, only the TC-1 really works with standard open barrel crimpers. I'm hesitant to buy their recommended combo because it looks exactly like what I already have. The TC-B and TC-C versions I can't find a cheap crimper for anywhere...Also the naming scheme seems to have no basis in any standard.So I paid 10 bucks for 100 butt splices I guess... Still not terrible ig

Good for butting wires together
