The numbers on the dies are in mm and they correspond to 10mm-8awg 16mm-6awg 25mm-4awg 35mm-2awg 50mm-1/0awg 70mm-2/0awg 95mm-3/0awg 120mm-4/0awg mine came with 8 dies 10-16-25-35-50-70-95-120. 8awg-4/0awg and I paid 41.00 off ebay I wish I would have got the 1 with 11 dies but this will do works great

Its a little harder to find than standard shrink tube but it's worth it in my opinion... and its doesn't cost a lot more than regular tubing. Thanks for the comment. 🙂

[@fasnuf]

I have these style crimpers and it can't crimp this cable tight enough before the die bottoms out. The crimp ends came with the cable so I know they're right. EDIT: I used the 1/0 die and it worked great. I threw a few pieces of solder with flux on the end of the cable and soldered after crimp, but it was holding very well without the solder.

[@SlipFitGarage]

I was confused by the first part of your comment. You were basically saying that this crimp tool cannot do what I demonstrated in the video..... Like somehow I used special effects to achieve my results in this video. lolol. Glad you figured it out. Thanks.

[@scod3908]

It can even vary with cheap thin lugs, that's the one downside of the die-style crimpers If you can't get a good crimp just size down and avoid over-crimping the the point it develops "ears"

[@mcxravin]

Your using the wrong lug. For example a lug designed for class 5 or 6 cable will be larger than a lug of the same size cable but class 2 cable. The difference being the amount of cores inside the cable.

So I did some research and here is what I found. The dies are sized for hard wire crimps which is why they do not work so hot on braided wire. That is why the wire sizes do not crimp correct unless you are using solid wire. Wonder if alternate dies are available? will look.

[@JeffinTD]

Excellent review. Looks like you got excellent fusion. Thanks for taking the time.

[@SlipFitGarage]

Thank you... It may not be 100% perfect, but its close..... and certainly much better than not using a crimper at all. (Some guys just use a hammer to smash the fitting) Thank you for taking the time to leave a nice comment. 🙂

[@JeffinTD]

I’ve seen good fusion from a hammer type crimper, though it isn’t as pretty. Seems hydraulic crimpers that do a decent job have become pretty affordable today, and are the way to go.

[@SlipFitGarage]

@@JeffinTD Sure, hammer crimpers work good too. In fact, I have a hammer crimper that I've used many times on smaller battery cables with good results. Unfortunately it didn't open wide enough to crimp the 4/0 fittings so that's when I bought the hydraulic crimper. When I mentioned some guys using a hammer in my previous post, I meant that they just smashed the fitting flat with a hammer, no crimper at all. I actually did that myself when I was a kid on some battery cables for an old truck that I had. It "worked" but it broke a lots of wire strands and eventually the cables pulled out of the fittings. Not ideal.

[@JeffinTD]

@@SlipFitGarage Yeah I hear ya. I’d done the hammer thing back in the day when a beater piece of farm equipment needs to be running. I thought hard about the crimper you’ve got, but saw TEMco had a referb that comes with warranty.

[@ruudmobile6726]

They indeed look great, but making a cut to check is alas the WRONG test... (eye test)... you need to pull the lug with a certain x Nm that should exceed the national norm (like euro NEN or VDE). We do high voltage cabling and the crimp tool is hydraulic and calibrated in Nm's as to firm is bad as well. Most people think fix = fix... well it is not, as it cuts in the wires on the edge end of the lug. And the sizes in the box refer to mm-squared.

[@SlipFitGarage]

Yeah, I get it. This is a cheap Chinese crimper. If someone was doing crimping professionally in a commercial or industrial setting.... they certainly will NOT be using a Chinese crimper..... and I never suggested this was good enough for that. But if you're making your own battery cables for heavy trucks or equipment, or heavy cables for a DIY solar system, (for example) then this crimper will probably be just fine. It's OBVIOUSLY not a calibrated tool. Anyone can see that. lol. It's a $50 dollar crimper. The crimper you use probably cost 40X the price of this one (maybe more?) and I KNOW your crimper does a better job. You get what you pay for. lolol. And yeah, the sizes are metric. It's been mentioned many times in this comment section. Thank you for the comment.

What did you use to strip that beast? The biggest I have found has been 6AWG, but I am stripping the same size as in the video, 4AWG.

[@SlipFitGarage]

I just use a razor blade. Lightly score the outer insulation then peel it off with either your fingers or pliers. Do not score thru the insulation and nick the copper wire. The wire is the video is not 4 AWG, wich would be pronounced as "four gauge". The wire in the video is 4/0 which would pr pronounced as "four aught". Aught is another word for zero. The "4/0" wire in this video is essentially 6 sizes larger than "4 awg" Imagine looking at a chart, as wire gets larger it goes down numerically until it hits #1.... So, 12 awg 10 awg 8 awg 6 awg 4 awg 2 awg 1 awg (after 1awg, numbers go the other way and end with "aught" 1/0 aught 2/0 aught 3/0 aught 4/0 aught

For a 70mm lug would you use the 70?, thats what i used recently with my new crimper, i think it could be tighter, or maybe i need to do few more pumps when its tight.

[@SlipFitGarage]

Sorry, I do not work in "mm" when it comes to wire/cable. I work in AWG sizing..... Other people in this comment section have commented that the sizes marked on the crimp dies are indeed metric. Take that for what it's worth. Also, once the dies make contact while crimping, extra pumps will not make the crimp tighter. Once the dies are bottomed out against each other, it's done! You could try a SAMPLE crimp with the next die size down if you still think the crimp should be tighter. Just be sure to experiment with scrap cable and fittings before crimping the real thing. Good luck. Thanks for the comment.

[@Kaosinlondon79]

@@SlipFitGarage i used to use the other one before i think its called its yQk handheld one, what i do find with this new one is the dies have a little play in them once they are on the crimper, what i might do is put a thin flat metal pieces either side so they don't move as much when crimping otherwise the bottom crimp and top crimp aren't always in line with each other.

​@@SlipFitGarage Not really. My comment didn't allude to any time frame at all. Not really relevant though. I could have just received it 30 minutes before I posted my comment, and I still wouldn't have been inclined to return it for something that was an obvious simple fix. Not unless I just felt like turning in my "man card". The fix was actually even more simple than I assumed. Once I bought some channel lock pliers, so I could get a grip on the handle, I was able to unscrew the handle, and inspect all the seals. Nothing was wrong with the seals. Turns out, it just needed more oil. The fact that I could point it facing down and it would work, should have been a clue. After a little research, I determined it used ISO 32 hydraulic oil. Then with a little more research, discovered that for this application, using SAE 10W or ATF fluid would suffice. I went with ATF. Works fine now.

[@unclefatbloke687]

Nicely constructed video. But at 0:09 you can see the cable printing showing AWG 4/0 (103mm²). 103mm² is just the direct conversion to metric from the cable maker because there are no 103mm² wires in Europe. There are 95 or 120mm². A 120mm² gauge is of course not going to compress the lug over 103mm² wire, so 95mm² is your best bet. I have to smile when you don't know what the die sizes mean. If they are clearly not AWG, what else could they be....?!

[@SlipFitGarage]

They could be some other form of measurement that I have never seen before. Ever. I have never done electrical work outside of the USA so why is that such a surprise to you? Why would I study metric wire sizing when, 1) I am not an electrician by trade, and 2) I have NEVER seen any wire or cable sold here in the US marked with metric sizing?

Interesting post and yup, looks like you got a very decent crimp. The 35 and 120 are standard metric cable sections. I`m guessing you will have standard sizes of 16 - 25 -- 35 - 50 - 70 - 95 - 120 - 150 which are standard metric cable sections in mm2. Would you use this crimper for mains voltage cables at a large control panel though? Might be a bit of a `leap of faith` where the consequences and cost of a bad crimp would be dramatic. I`d dip out and use a tried and tested crimper just to sleep easy! I might be wrong though and could be underestimating the quality of the product.

[@SlipFitGarage]

It's been a while since I made the video (I should re-watch it) but I seem to remember saying basically what you said. If I was crimping mains in a commercial panel where I needed to use certified crimp terminals with the correct corresponding crimper then no.... I would use the high end brand name equipment. But then again, If I was doing that job in the first place, I would be charging accordingly so the cost of those terminal and tools would be included in the price of the job..... For your own hobby stuff such as solar systems and battery cables, etc... I think this is fine. Again, if I was doing this type of work professionally, "for-hire" I would absolutely be using the the brand name equipment. No question. Especially since the customer is ultimately paying for the tools and supplies anyway....

Anyone ever try this tool on hydraulic hose?

[@SlipFitGarage]

This tool IS NOT designed to crimp ANY hydraulic hose fittings. This is a wire crimper ONLY. Hydraulic fittings have a very specific crimp spec. (Measured by the thousandth of an inch, .001) In fact hydraulic crimp fittings are manufactured to work with a specific type/brand of hydraulic hose and they should never be mismatched. Infact, most hydraulic crimping machines are designed to work with a specific brand of hose and fittings. For example.... if you have Parker brand crimp fittings, they are specifically designed to be crimped onto Parker brand hose... and are usually crimped with a Parker brand crimper. Everything is engineered to work together to provide a SAFE crimp that will last without leaking. The same can be said with any other brand of hydraulic fittings/hose/crimper. The dies on this WIRE crimper do not evenly close together in a 360 radius like a hydraulic crimper, and the dies are also not deep enough to properly crimp the entire collar (crimp area) of a typical hydraulic fitting. Please DO NOT try crimping hydraulic fittings with this WIRE crimper. The end result would be very dangerous and most certainly leak like crazy. A propper hydraulic fitting crimper, and this WIRE crimper have absolutely NOTHING in common. Thanks for the question.

[@bendent9002]

I knew it is for wiring, but like lots of other things, I have used certain tools for other applications. But the dies on this tool is quite thin. Even if you could make it work, it would have to be doubled up or crimped two times right beside one another. I'd assume given the need of very close application, you could use this in a pinch but certian care as to not crush the inner coupler or just do as I intended and source an actual crimp tool for hydraulic applications.

[@SlipFitGarage]

@@bendent9002 Hydraulic hose has a wire reinforcement layer between the rubber layers. If the fitting is not crimped exactly right, those wires inside the crimp can/will break and the crimp will be very weak, and very dangerous! We have no way of knowing if the wires get broken during the crimp process... thats why we use fittings/hose/crimper dies/crimper that were engineered to work together and provide a proper crimp without breaking the reinforcement wire layer. I can almost guarantee the dies on this wire crimper will crush a hudraulic fitting in such a way that at least some, if not all reinforcement wires inside the hydraulic hose will be broken or at least somewhat compromised. Its not the outside of the crimp that is important, its what's happening on the inside during the crimp that really matters. This wire crimper CANNOT provide a safe hydraulic crimp. Its not even remotely possible.
