Getting an updated Yong Heng

Look for the writing on the side that says Yong heng. Those are the original. But now people making so many clones it's hard to tell. Someone can even put the writing on a clone and you wont when tell the difference. Clone or not, they will still get the job done. Many of the clones used 1 piston ring. Which is mostly the failure rate of these clones. The real yong heng use 3 rings on the high pressure piston side. Some clones will use 3 and 4 rings. As long as your used 3 or 4 ring it's all good. You just don't wanna end up with these clones with only 1 piston ring.
 
So now I am more confused than ever! :) Does anyone have a link they can share, without violating Airgunnations policies, to an updated Yong Heng that I can buy?

Define updated. If you mean based on the original and untested theres many I'm sure. Just get a genuine one, that us advertised as a YH and make sure it says it on the side. Ask the seller (ebay) to confirm. Mine is 2+ years old and going strong.
 
On the papers that came with my YH it says that it is a 7 generation. So maybe they are getting good?

Oh and they do not need lettering on the side to be genuine YH!

No? All the ones that say Yong Heng have it on the side on that site.


So an unmarked compressor from the same factory is a fake?

Or do they sell knockoff's of their own product on their very webpage???

You'll have to ask them, look at the failure rate of the clones. Much higher than the original.
 
Yong Heng is only a trade name. They do not manufacture anything. If you order enough units, the manufacturer will print whatever name you like on the side. Other names like Tuxing, Vevor, Davv or the cheap home compressors from the large auto and hardware chains, are probably made by the same factories. They all seem to use common motors and crankcases. If you try looking up who the actual maker is, you will find some of the parts suppliers claiming to be the manufacturer. If you look a little harder, they all turn out to be just vendors. Calling different brands clones is a bit silly as some don't even look like each other and just about everything in China is a copy of somebody else's idea anyway. Have a look at the Davv pump, it was around before the Y.H. and looks exactly the same, wouldn't that would make theY.H. a clone of it? Calling something a clone just because it doesn't have the right brand name on the side is ridiculous. 
 
Yeah some good points there eaglebeak. I'm referring to ones that are half the price as the yh branded ones. If theyre the exact same thing then more power to the buyer. I just remember in that survey m.coulter did the "clones" had a higher failure rate. And have seen it happen more on here to reflect that. Like the 1 piston ring on the high pressure side vs 3 or 4 on the yh branded ones.
 
I bought my Yong Heng from the on-line shop of the factory in China directly. How do I know they are the factory or very close to the factory ? I have once asked them how the rings on the 2nd stage piston should be replaced and within half a day they took this video from the factory and sent it to me via on-line chatting app :

I have also asked them quite a lot of other questions about the compressor and they were always able to answer promptly and in very good details. Just the other day I sent them a picture of the first-stage piston I took out from the compressor and their eyes were so keen to spot that I have installed the rings upside down :

I don't know their sales channels outside China but base on my experience Yong Heng is more a factory than just a brand name. At least in China, I have yet to see a compressor that is identical to Yong Heng in appearance but carries another brand name. There seems to be an official shop of Yong Heng on Aliexpress but I am not sure if it's genuine : 

I have got my YH for about 1.5 years. Almost 7 hours of run time. Still going strong. 




 
My point was to point out that there are no actual Yong Heng clones. I would bet my balls that another Chinese company would bother producing an exact copy of a cheap but popular product, using inferior parts and then try to pass it off to the world with false advertising. It would make sense if the original product was uber expensive but in this case, there's nothing to gain as it would be impossible to build these things any cheaper than how they are mass-produced now. That being said, there are still vendors out there that will try to misrepresent what they are trying to move or some that use generic pictures when advertising their merchandise. Some just move stuff via the web from other suppliers directly to their destinations. That's why it isn't any use trying to confirm whether the item is correct or not before ordering. The seller has no idea of the particular details of the product concerned.

Here is an example of a legit Y.H with a different name on the side. The company claims to be the manufacturer but it appears to be only the producer of the gauges. If there is a company called Yong Heng that is manufacturing and not just assembling these, I would like more details as I can't find any information about them online. There are companies with that name but in unrelated industries. Perhaps you could share that information and some pictures of their foundry and machine shop. Just because they sent you instructions about the correct orientation of the rings does not prove that they are manufacturers. A company producing these pumps in the numbers that these are coming out globally would have to be huge and very well known. A simple google search would be able to access such a company. https://xkguage.en.made-in-china.com/product/nXREIcUvVHrY/China-4500psi-300bar-High-Pressure-Yong-Heng-Air-Pump-Pcp-Compressor.html

I bought mine from a U.S. distributor on Ebay who has a good track record and 98% positive feedback. Plus, he accepts a picture of any warranty claims, so you don't need a video or to send the compressor back to China for repairs.

https://www.ebay.com/itm/30MPa-Air-Compressor-Pump-110V-PCP-Electric-4500PSI-High-Pressure-YONG-HENG/283078570203?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

It's no guarantee of anything, but everything in the box said quality, and I have had no difficulties with my compressor.

So all said, it's a $235 educated guess. I suggest buying from a U.S. located distributor with some kind of track record, other than their own claims and two initials with five stars for a testimonial. Ebay, Amazon, just try to go through someone who chooses their distributors and at least tries to maintain their reputation as an on-line store.

To the best of my knowledge, there is no way to know if you have the updated, stronger built units. Those changes were back a few months ago, so you can ask the distributor, just don't expect them to know any more than you do. However, if trouble does take place, at least you can order the stronger repair parts from Yong Heng. These things are fairly simple, with several Youtube videos on repair...so you don't need to be a Rocket Surgeon to fix it.
