Someone did post it in the past.. yongheng uses a one piece ring over an oring. Tuxing uses split ring... easy peasy
I have some tuxing seals I could send to someone for a trial. Just let me know how many.
Tuxing second stage seals WILL NOT work on a yong heng, I have tried...I'm not sure where you can get second stage seals, I got mine thru the Ebay seller I bought my compressor from. I paid the seller, he contacted the factory, submitted my order and the factory sent the parts directly to me...How I did my seals without damaging them. remove the entire cylinder head then piston/conrod, you can't do this with the piston and first stage head in place....HOT water, soak the seals for a few minutes. Then, using a small set of needle nose pliers, GENTLY stretch the seal by slipping it over the plier jaws then spreading the jaws. You only want to stretch the seal enough to get it slipped over the piston and then seated into into the piston grove on top of the oring without damaging the seal. So, stretch a little and try it, to tight, stretch a little more. You may need to reheat the seal during the process... Once all three seals are on, soak the end of the piston, seals and all in HOT water for 5 minutes or so. You only need to submerge the seals and 2 stage piston end... I then used my index finger and thumb rolling each of the seals between them and applying pressure so the seals start to take the proper shape and size. Once they seem to be in the groves, gently, and I mean GENTLY, start them into the 2 stage cylinder head bore. You will need to rock, twist and generally coax each seal into the bore. TAKE YOUR TIME! if each seal, doesn't slip in with a little coaxing, heat it all back up, and try again.Once all three seals are in the bore of the cylinder LEAVE them there until they are completely cooled. figure 15-20 minutes to take a good set in the bore.Once cooled, slip of the head, and reassemble the compressor. once you get to the point of slipping on the second stage cylinder, again, GO SLOW inserting the piston into the bore.Good luck!

And when you do they are expanded and won't shrink back to their normal size.I don't believe the tuxing split rings will work on the Yong Heng.

Here’s the thing though, would you really just replace 2nd stage rings and no other seals while it’s apart? Not I, having done many motorbike/atv motors you’re just begging for the old stuff to leak.
