Yes ebay...or alliexpress... I usually buy the kit with piston rings gaskets and valve...its cheap....you can just buy the 2nd stage piston and just change it. I rebuild my Yong heng 5 Times... Here to help

The second stage piston measurements of the Yong Heng are different from the Vevor. That's the problem.

I had some at one time but couldn’t figure out how to get them on. They are hard and I suspect you’d need a special tool to install them.

The head of the piston (if like the yh) unscrews. This allows the center ring to be easily replaced and the other two relatively easy. If they are the type that has the oring underneath, they can be tricky but doable without deforming the seal.
If indeed that is the case, I can post pics of how I do my yh, I just don’t want to muddle a vevor thread with yh stuff if it doesn’t apply. Early vevor had 1 ring, this one appears to have 3 like the yh.
Easiest is to replace entire piston since the rings are already installed.

The problem is that I can't find the piston or rings for the vevor compressor.
They are not the same measurements as Yong Heng.

They might have to be removed but probably destroyed in the process with a dental pick or something similar. If they are similar to the AirVenturi 4500 and Nomad that are not split. The replacements for the Air Venturi's have to be gently stretched open with a cone shaped tool just enough to slip over the piston then reshaped so that the cylinder can be slid back on. As others mentioned, maybe replacing the whole piston might be an option. The problem is, there are so many variations of seals and unless someone has gone through that job of doing it already and sourced the correct seals it might be a crap shoot finding the perfect one. Is there a service number for Vevor in the paperwork? Good luck and keep us posted.
These are the ones on the AV 4500.
