Hollow core rams are exceptionally handy, I own two different sizes and they have saved the day time and time again. Good to know about these from Vevor and the low acquisition cost.
Thanks. I am glad that I was able to help a bit.
Nice one, that's a very nice looking hydraulic ram. Thanks for the review. Cheers, Aaron.
Thanks Aaron.
I've bought quite a lot of stuff from VEVOR and been quite satisfied.
Very good to know. I will have to check out other items from them.
Just since you commented on how well packaged the product was, I recently had a very similar experience. I ordered a wheelchair that was manufactured and designed by the Japanese, but produced in China, of course. The chair itself was unusually high quality, even parts that are not typically visible like welds were remarkably well done. It was notable amongst all products. As impressed as I was, I was far more impressed with the engineering behind the packaging. There was absolutely no plastic used, everything was folded corrugated cardboard. Admittedly, by the time I broke it all down, it completely filled a pickup truck bed. The design was stupendously complex. They used tab and slots to create cardboard bricks of sorts, everything was perfectly nested. It took me over 3 hours just to flatten all the cardboard. I have always heard of the wonders of Japanese design, I have often been impressed with their products. This was a complete world apart. This was more impressive than when they started putting ziplocs on shredded cheese! I regard that as one of the high points of packaging development in the last hundred years
As a wheelchair user I’m interested in any additional information you can share . Thanks much.
For the Japanese packaging is an art form. You can see their influence everywhere.
Thanks for the review. Good job!!!
Thanks for watching!
Thanks for the review. Much appreciated. I purchased one of these import rams in the 20 Ton version without the through hole. I also purchased an import hand pump. Both had 3/8" - 19 BSPT female threads. That has made trying to find fittings, couplers, and adapters to connect a hose between the two a nightmare, but I eventually found some adapters to convert everything to NPT. From what I understand, pipe threads coming out of China are going to be BSPT (British Standard Pipe Taper) or it may be BSPP (British Standard Pipe Parallel). Parallel or Straight threads are common in things that don't need to be air or water tight, like electrical conduit. You would think that there would be a load of these BSPT fittings on eBay or Amazon coming out of China, but that is not the case. As well, I was unable to find ANY quick connectors in a BSPT thread, be it the Enerpac style or any other. So unless you buy a kit that includes Pump, Ram, Hose, and connectors, you are in for a frustrating, time consuming, and expensive adventure. I tried to get the Ram apart but was unsuccessful. If you or anyone can put up a video on disassembly, that would be greatly appreciated. Thanks
Thanks for sharing your research. Hydraulic fittings are an insane category with seemingly hundreds of variations. Even staying within one brand has its difficulties. Enerpac, for example, makes a tone of different connectors. This was a really frustrating project.
As for the disassembly, I took apart a different cylinder and repaired it. The trick seems to be to remove the hydraulic fitting on the bottom and pull out a retaining pin that is hidden inside. I hope that helps.
@@DudleyToolwright Thanks. I did take out the fitting and looked for a pin, but unless I'm missing something, it appears to be a blind hole with an intersecting bore for the fluid to enter the ram. So, still looking for someone to demonstrate how to disassemble. These rams are very popular now, but seem to be designed differently than the typical import porta power rams. Thanks very much
Were you able to find a coupling that was the correct fit? I'm in the same position and too worried to do the same thing the brave guy in the video did because I'm using an electric hydraulic pump, and worry something would happen in a negative way.
@@RipperRUclipsOfficial Yes, I did find some adapter fittings on eBay, but they may not always be available. It took a lot of searching
1st stick with the enerpac style high pressure fittings. These hollow cylinders are the only way to remove pins from equipment. Very helpful tool. Temco industrial sells a very nice selection of hydraulic equipment and fittings. Awesome warranty also.
Thanks for the tips!
BSP thread there Rob . They are a bloody handy size ram . I use them at least once a week for jacking machines & pulling bushes into bores . Used to just see Enerpac & Simplex , but now there are lots of different brands . Also made with aluminium bodies as well .
Thanks, Max. I am not terribly familiar with BSP threads. Another commentor said that the threads were likely 3/8 BSP. I would love to see some of your use cases. You are a fount of knowledge. Thanks for sharing it.
@@DudleyToolwright thanks . BSP threads are more common than most think . One day i will try & film some hollow stem jack shots . Cheers .
The thread is probably 3/8 BSP which would be 19 TPI and 55 degrees (whitworth form), because why not... Variations on BSP threads are used all over the world (outside the US) for pipe threads. It's something that never really got metricated properly.
I was thinking the same after Robert said neither standard or metric threads would match up.
Definitely BSP.
Thank you so much. I am a bit unfamiliar with this thread type. I thought Whitworth was an older dead "standard'. Live and learn. I really appreciate you taking the time to help me and probably others, out.
@@DudleyToolwright Whitworth threads have been obsolete for most of my life, for everything other than pipe threads. Here in the UK and in many other countries I know about (maybe even most of the world, I don't actually know), BSP is still the primary pipe thread in use - there are even standards in other countries that define pipe threads in metric that are actually just BSP. All the plumbing fittings in my house use BSP threads, usually with everything else being metric. BSP was the standard in the US as well until sometime in the 40s (probably WW2 at a guess) when the US introduced new standards that the whole rest of the world ignored completely.
@@DudleyToolwright Funny thing is in the last few months I have run across British Standard threads twice doing repairs. I bought a thread gauge and started gathering taps and dies for them.
Make sure if you are using Teflon tape, you DO NOT start the tape over the end of the threads, keep it back 1 - 1 1/2 threads. Or better yet use Telfon Paste. Loctite/Permatex makes a good one.
Why?
@@calholli Because if you have the tape over the end of the threads, when you start screwing the fitting in, it will cut the tape and you will end up with shreds of tape in the system. Tiny bits of tape are solids that plug orifices etc. Paste doesn't do that.
I had heard the tape not over the edge recommendation from aVe as well. I was not aware of the paste. I will have to look for that. Thanks for the great advise. It is really appreciated.
It occurs to me that the hollow passing all the way through makes this a pretty ideal component if you wanted to construct an overly complicated arbor press. When you built your test stand, it looks quite a bit like a laboratory press, that's what spurred the idea. Theoretically You could turn several adapters on the lathe to match up to different tool holders. I don't know what mill you run, but the tool holders with an interference fit always give me a little bit of trouble, a little press like this would be quite helpful. I always preferred The hand pump, it seems like you can get a little bit of feedback
A really interesting idea, thanks. I had not considered that the hole through the middle allows the ram to both push and pull. Really neat.
I bought a 50 ton from those guys, it was $100 and it’s been great, same thing powerteam brand is like 3k
I appreciate the info. It's good to know there are decent options out there.
thanks for the video been looking for one like that cuz I need to make a hydraulic ram puller and need a hole in the center to pull the rod thow it thanks
I'm glad it was helpful in some way and the idea that the hold lets the ram push and pull is really useful. Much appreciated.
When installing Teflon tape, wrap it in the same direction as the thread so it doesn't loosen.
Excellent tip. I believe that is what I normally do. I also stretch it whilst turning.
Where did you get those washers to even out the pressure on the point of impact?
McMaster Carr.
Thanks for sharing 👍
Always taking the time to comment is really appreciated. Thank you very much.
Is this cylinder hollow all the way through? On Vevor site I did not seen a single picture showing that.More than that on ebay I saw a hydraulic schematic of this piston showing the oppozite....
Yes it is. You could run a bolt all of the way through and pull something towards the base rather than pushing things away.
The original coupler is called " ZG3/8'' " it is similar to " Enerpac A Series "
That is really helpful. Thank you.
Teflon tape on hydraulic threaded fittings is a No-No. The way you put the tape on is as good as you can do. If the tape is put on all the way to the end, it stands a chance of rolling off and getting in the system. Loc-Tite makes some great hydraulic thread sealant.
Thanks for the tips. I suspected as much. I really appreciate you taking the time to help me out.
I agree, if it wasn’t for all the awesome “chineezium” stuff, most people wouldn’t have anything to then complain about. Yes some are junk, but we have junk too. Made in USA, Germany or Japan.. doesn’t automatically mean it’s great. Just do the research and get the good ones.
I completely agree. I would even venture to guess that Enerpac probably has some of their parts made for them in China, Taiwan, etc. It's really hard not to and still be competitive.
I agree totally on the ridiculous amount of fittings particularly both hydraulic and pneumatic. I sold hyd/pneu aftermarket seals for 19 years. Same deal too many design configurations. Reason being, so you are forced to buy from the OEM for replacement parts. Automotive oil filters is another one, toooo many designs!
Pneumatic is by far the worse. Just one machine alone I maintain has 88 cylinders of all different sizes, and all the solenoid valves to go with it. It is a Ueropean machine with a mix of BSP and NPT. It is a major headache just for one machine, we have several.
It's nice to know that I was not too far off base and sad all at the same time.
The through hole allows you to pull using the ram
Thanks Chuck. I am embarrassed to say that I did not see this utility. Several commentors have made the same recommendation. I really appreciate the tip.
I sold hydraulic fittings and made hoses and I never figured out all of the variations. Every time I thought that I had it figured out, new fittings were introduced and then the metrics came onto the scene. Seemed like every machine and manufacture had their proprietary fittings. I was frustrating to say the least.
Yes Steven! Think about the maintenance guy that has a bunch of jobs waiting for him and each piece of equipment has a different manufacturer fitting. That's why when ever I order hoses, I also order fitting for those hoses. Over time we replaced all the oddball manufacturer with a standard.
It would be nice for someone to make an open standard and then have manufacturers agree to use it. Oh, I know, I shouldn't dream aloud...
oh and i use teflon tape on air fittings with 4500psi and never have any leaks
Great bit of info. Thanks. I was not sure at all.
@@DudleyToolwright dont know if you are supposed to but it workes for me
Great to know. I love to hear about personal experiences.
ITs nice when someone other than yourself sees the truth im pretty sure common sense in our government has gone out of style
I'm wondering if the Teflon tape was all at the back because they installed it the wrong direction and it all just got pushed to the back as it tightened instead of staying on the threads otherwise cool video 👍👍👍
Good question! One of my friends suggested the same thing. Perhaps you are spot on. Thanks!
Take a look at Squatch253 D2 Chassis Rebuild Episode 27 (from about 10 months ago) around the 12 minute mark for a hollow ram use case.
Thanks. I definitely will.
i got 24mm male going into my vevor 20 ton but the portapack has the 3/8. what fitting do i need?
I am not entirely sure. There are literally hundreds of different hydraulic fittings. The industry is horrifically fractured when it comes to standardized fittings. I wish I could be of more help.
@@DudleyToolwright whare did you get the one you put on?
What threads on the Vevor? I am sure you can just look it up in the user manual....
Oh, that's right, NO chinese crap has user manuals, but if they do, they are in illegible chinglish.
Glad you did the test because I couldn't find my 100K load cell anywhere 🙂
Your test setup was very clever, and you know what they say: 'It's not science unless you have to hide behind something'.
And there was quite some pucker factor around 60K, so passes my qualification, looks like a pretty good tool: I would totally purchase.
Single sheet user 'manual' had zippo and contacting them did not help either. According to a generous commentor the threads were probably a 3/8 BSP which are 19TPI at 55 degrees. Nutty.
I'm always doubtful of 'hydraulic ram' ratings, and for a very valid 'physics' reason. You can EASILY calculate the capacity of a ram, by simply knowing the diameter of the moving 'anvil' (rod or bar) it uses. Since ALL 'general use' hydraulics is based on the design limit of 2,800-psi (work pressure), knowing the diameter of the ram itself, you can do your own math.
Take the diameter of the ram and, using the equation to find the area of a circle (A = pi x r^2), simply plug in your radius (half your diameter). So, with a 4-inch diameter, you have A = 4*pi, or about 12.6 square inches. Now, multiply that times your pump pressure (2,800 psi), and you have the potential of about 35,185 pounds-force (about 17.5-tons).
Explaining this (and knowing from a lifetime of working in hydraulics), I can say that 'while new, sure, you might get another thousand pounds out of a new system, new seals, etc., that is roughly what 'life cycle capacity' will end up being. It's also a great way not to get burned when dealing with 'Chinomium products' that claim far more than they are actually capable of.
To get to 30+ tons of force, it would take a ram diameter of 5.5-inches...and this jack doesn't look like its that large, at least not in the video. Likewise, there are 'SPECIAL HIGH PRESSURE' hydraulic systems out there that go beyond 2,800-psi in working pressure...some approaching 4,000-psi (and large industrial products that exceed that), but if they aren't marked 'SPECIAL HIGH PRESSURE', it is very unlikely they are...as the components required to 'stay together' in such application are VERY expensive (ask anyone who's had to replace 'special high pressure' hoses on the occasional consumer product equipped with such items).
I don't mean this to be a negative comment...merely a warning to anyone who thinks they are buying what they in fact, may not be getting...always do the math, it will save you heartache in the long run.
These are high pressure cylinders that operate on 10000 psi. I use them to remove low pressure heavy equipment cylinders and stuck pins. These hollow cylinders are larger in diameter to satisfy Pascales law.
Interesting info. Thanks. I am onboard with the math, but the hydraulic pump I am using (enerpac) claims to be able to put out 10kPSI. It would only take 6.6in^2 to get 66,000lbs. The 100,000 load cell I was using verified that I was easily able to get to 66,000lbs and beyond.
the rod diameter , bore diameter and piston area are all wrong on the datasheet, stripping down this tool to measure you find the capacity is greater than 30T hence you achieved greater than what is rated, we work it out as 14% greater but don't take my word for it, check it yourself. Ensure you do your own proof checking on this prior to use.
Hi do you know wether I can use a single acting RAM on a double acting pump? Thanks
I am far from a hydraulics expert and have relatively small knowledge base in the topic.
i will say this i am an American by birth and as patriotic as i can be i want to buy American products and here is the problem chinese indexable ccmt tool holder $7.99 American ccmt tool holder $240.00 . so American 30 times higher makes no sense you cant tell me that American companies cant sell the ccmt tool holder for $25.00and make a profit and people like me would buy them but 30x the average American can not afford that but i do buy American when i can afford it . keep up the good work oh and enerpac could sell the piece you reviewed for $400.00 and make a profit but they know industry will pay more so they rape the people its called GREED!
We are definitely of the same mind here. Pure Capitalism is inherently evil, in that anything is okay as long as profit is maximized. Morality, is not really a factor beyond the same profit goals. On top of that, thanks to the stock market, companies as a rule don't really look at long term profits much either. That is why it was historically okay to dump industrial waste into landfills where it seeped into water supplies. Okay, okay, I'll get off my soap box...
@@DudleyToolwright i agree like now with this green deal what will they do with all the lithium ion batteries from the electric cars it will be no better than nuclear waste honestly fossil fuels are actually the cleanest form of energy available to us at this present time mother nature will heal itself if it is given a chancejust like global warming . why cant people understand the temps on this earth have changes for millions of years and there is nothing we can do to change it but im just a dumb person with no degree from MIT so im stupid and dont know what im talking about so there is my soap box sir
In a democracy, everyone deserves a turn. Cheers.
Run a threaded rod through it to make a custom puller
That is an excellent suggestion. Thank you.
Probably BSP. I am very far from an expert, my understanding is that in Europe and Asia the JIT fittings have become relatively standard over the last number of years. In fairness, I have heard this phrase regarding many different lines of fitting over the years
Another commentor said that they thought that the fitting was 3/8 BSP.
Que viscosidad de aceite hidráulico a puesto?
Esa es una buena pregunta. Usé el fluido hidráulico que compré para mi torno. Era Mobil DTE 24-ISO 32 (SAE 10).
Parker Hanafin Hydraulic equipment US made at least five to eight times price of Europe or UK equivalent if you use them.
Thanks for the info and suitable nutty. Although in the US liability is probably a significant factor.
Will these work in any orientation?
I believe so. They are an enclosed system with no air space, as far as I know, unlike a bottle jack that siphons from the bottom.
Hollow ram for pressing flanges on with treaded rod
Another useful tip, thank you.
Where do u buy the coupling?

I think I'd run a 3/8 bottoming tap through it just to be safe.
Excellent idea. I was going to do something like that, but then I was going to have to take the cylinder apart as well to get the metal bits out. Still, I should have...
what is the female fitting called so i can find one please
There are too many to count. Mine was an Enerpac C604. I bought a knock-off.
Could be 3/8 BSP thread.
You are the second to recommend that and I think you are all right. I was not aware of this thread form. Thanks for helping out.
There is China, and there is china. For both, buckled corners are nearly always what one can expect. It's okey if there is a buffer zone inside that can absorb the impacts, but that's not always happening.
Yes, give them thumbs up for that box! Impressive box.
Whow, 3/8" fits. China usually use Metrics (millimeter), but for electrical current the China 1 Amp often corresponds to 1/2 a Metric, or Imperial Amp....
Tell me or I'll give that Chinese guy a shot..... I'm using several Gutling guns on a bad Chinese but he are like made of self healing rubber...
O ring missing... Got a mill totally without lubrication for the lead screws...
Spare parts like o ring etc. Ask the seller. I have, for different items, and they don't know what that is. Asking specifically for certain parts the answer is: No......
Looking for spare parts is probably iffy, I will definitely ask, because it would be very useful if they were available, but even if - how long?
"Extra strength all thread" #5???? #5 threaded fasteners are hardware store run of the mill. #8 is a higher grade and stronger.
Tis true. I bought all #8 washers and nuts but only #5 threaded bar because the cost was about double for only 25000PSI more and I thought I had a large enough safety margin already. Heck the cost of my test setup, excluding the 100,000LB load cell, was almost the same as the cost of the ram. Funny that.
Use paste pipesealent
Thanks for the tip.
Chinese manufacturing has great ideas, designs, technology etc. the big problem is that they lack QC. If you are lucky enough to buy one from a fresh mold and they had fasteners in stock, etc, you get a good tool, if you get the one they squeezed out of a trashed mold, and left out half the fasteners becuase they ran out, you’re screwed, luck of the draw.
They've gotten a lot better in the last 5 years though. A LOT better. For example, rifle scopes and red dots. You can get excellent stuff out of china now, such as an Arken, Holosun, Primary arms.. ect. ect.. Excellent stuff now, where as it was hit or miss 5 to 10 years ago.
Interesting observation. Thanks. It does make some sense. It's one thing to make a good part and a whole other thing to continue to do that consistently.
@@DudleyToolwright exactly, it’s just something to keep in mind at that price point
Spot on.
