Need Replacement Piston for Vevor HPA Compressor

[TAP]

 Does anyone know where I can purchase a replacement 1st stage piston for a Vevor HPA Compressor?

This compressor is not the same as a Yong Heng model.

I would suggest you to check if the Yong Heng piston, which has got a much thicker top in the new version, is compatible with your compressor. I can do some measurements on my Yong Heng piston if it will help.

I don't know if anybody sells just the piston for those but I think that this whole top end is the same and only $40 USD plus shipping. I'm fairly sure that a Tuxing or Yong Heng top end will also fit if you replace the whole assembly. The second stage pencil pistons are all different and can't be interchanged. I'm not sure if the first stage piston and rod is compatible with other models.

I believe the tuxing and the vevor are the same but don't want to buy something else that doesn't fit. I have a vevor myself and have already ended up with second stage rings that will fit the YongHeng but not the vevor. I'll be watching this thread with interest and if airgunfans would measure the piston that would very helpful thanks. By the way I found the second stage rings for the vevor here. https://www.aliexpress.com/item/33001215265.html?storeId=1230786&spm=2114.12010612.8148356.55.b48a1b79WFRrNt 



Wow, that looks exactly like the top end for my vevor. Thanks. https://www.aliexpress.com/item/33032335167.html?spm=a2g0o.detail.1000060.3.479d2f47moEmDe&gps-id=pcDetailBottomMoreThisSeller&scm=1007.13339.128523.0&scm_id=1007.13339.128523.0&scm-url=1007.13339.128523.0&pvid=7e0df1d2-0d60-4621-a9c9-9c87b4b7a2e1

Here are the measurements of the original piston of my Yong Heng :

Thanks for the link Eaglebeak I ordered the top end for my Vevor. If I have anymore problems getting parts for this compressor my next step will be to purchase a Daystate compressor.

I forgot to mention that it would be a good idea to contact the supplier to confirm that the whole assembly is included. From my experience, they usually supply what is shown but occasionally there is a misunderstanding or translation issue between the retail shop and the manufacturer or wholesaler about the proper description. $45 USD does sound a little cheap for all those parts. I have purchased a few items from that shop before and haven't had any problems.

On July 12th I ordered the Vevor top end from "AliExpress" for my compressor and today (July 23rd) I received the entire top end delivered by UPS which consist of the top head, cylinder, piston, 3 metal coolant tubes with connectors, 2 cylinder gaskets, muffler with element, 2 bleeder valves and a bag containing miscellaneous seals, orings and other parts. I now have everything needed to do a complete top end swap out. The total cost shipped was $70.24.
