Has anyone purchased a YONG HENG recently?

Jump to latest Follow Reply
How recent? I got one about a year ago with a different model # (30QB-SD). It's been stellar! Seems more robust than my old one that lasted 3.5 years. Got it on Amazon with extended warranty after VERIFYING with seller it was authentic YH. It's the simple hard cover, non auto-stop version. Hope that helps.

Insist on "YongyIheng Pneumatic Company," spelled out on compressor ID plate. Chinese copyright law is laughable but at least they draw the line at false representation of manufacturer. Blank, "Made in China," or another manufacturer noted on ID plate is dead giveaway of clone. WM

Along my 5-6 years using YH I have learned what spare parts to buy in advance.
The high Temp is the worst enemy for the piston rings.
Earlier years I was replacing the second stage rings only, but soon enough I learned to buy the entire piston+crank kit assemblies.
I need one of these in average ones in a year, and replacing in less then an hour. My total cost for maintenance- with parts plus a beer and a coffee is way below $50 per year.
Last month I got two piston kits from aliexpress, but when I wanted to store in the YH crate I discovered that I already bought two piston kits last year.
So I guess I am set for a while.

My new compressor arrived at lunch today, fast shipped from NJ to MD.
Auththintic looks like the same batch that @Gerry52 got his from. For 230 I am happy to have a backup!
They actually have a real fan now vs the paddle wheel that I had to change!
I'll test the new one in a day or so, but I plan to continue using my 2.5 YO until it gets real slow or quits.

wow, I too inherited one recently. Not sure if it's worth using. I'm currently using a GX Cs4i. Do you guys think these are still worth it to use as a backup. Sorry i'm still kind of new in the PCP world.

Yeah, they're MORE than worth it. Just keep it cool (extra external fan blowing on it, large water reservoir with some ice in it, etc), drain the cyclonic water separator on left side for a few seconds every 5 minutes of run time, give it a few minute break every 15-20 minutes of run time. NEVER start or stop it under pressure. It will top off or fill WAY faster than the GSX4 but some people think think they're more of a PIA than the GSX4. Once they're set up it's REALLY not much of a pain. The "archives" on the forum have a ton of tips now to run them & make em last (Biohazardman's Yong Heng posts). They kick ass for the price imho.

Wow, Thanks for the info. I watched a few vids on youtube. But they all seem like old post. I wanted to build a radiator setup with cooling fans. I was just worried that i'd be wasting my time because it's old tech vs the new stuff out now. Thanks that just gave me motivation to get this setup going.

I made a closed loop cooling system for a YH, a couple of years ago, to allow me to use it at the range. It weighted close to 60 pounds, so it was OK portable, but wouldn't wish to pack it up too many stories.


The radiator I used was a Nissan Xterra heater core. If it is of value, I can offer what I used and how I did it.

I found that the closed loop cooling system was not sufficient for filling a 45-minute SCBA tank, but fine for rifles. Cooling from a water faucet was the best cooling solution that I found, for filling tanks.

I finally decided that I was going down the wrong path in using tanks and home compressor for filling my guns, and switched to a GX CS3 for direct filling at the range. That was the best solution for me, but not necessarily for others, of course.

Here it is mocked up which makes the parts easier to see.

Here's my Florida garage setup, required water coalescing and molecular sieve filters to handle humidity, total cost less than $400. I pre-chill room temperature compressor to 18 degrees C range with ice-cooled water. External fan on high during fill session till everything cool to touch at end. Only fill guns, 4-5 at a time, spaced 30 minutes, changing ice bottles, as needed. Dump water in washing machine after fill session. WM

That’s good news. I currently have one in transit from the same eBay seller. Are you using a tank or filling directly into your air rifle? Any additional filtration or water/oil capture?
