Vevor replacement piston seal?

[shinyknight]

Hi. I look all over eBay and AliExpress and can't find the high pressure seal for my vevor compressor. It came with 2 spare but I've used one. So only have one left. I ordered an tuxing piston with 4 split rings from AliExpress but someone said it doesn't fit. (Will know if fit or not in 2-3 weeks). Anyone know where I can get replacement seals for the vevor? Post link/site. Thanks.

check the lower left picture in this repair kit, think this is it.https://www.aliexpress.com/item/0-40mpa-High-Pressure-Air-Pump-water-cooling-Electric-mini-Inflator-PCP-Air-Compressor-220V-repair/32824128520.html?spm=2114.10010108.1000013.3.427f5cb5j7debE&gps-id=pcDetailBottomMoreThisSeller&scm=1007.13339.99734.0&scm_id=1007.13339.99734.0&scm-url=1007.13339.99734.0&pvid=29c01ad2-b92a-4143-8491-3af07fadcf60

There's so many items on that list. Not sure what comes with the kit. I don't really need all that other junk. Just need the high pressure seals. Wish they just sell the seals in packs, like 10+ or something. Even if that kit comes with the seals, there's only 2. I'm the kinda guy who wants like 10+, maybe even 50+ as spare.

Check this thread, you might PM Cosmic to find out where he ordered them from.   https://www.gatewaytoairguns.org/GTA/index.php?topic=149040.0

Tuxing/yong heng pistons are larger with 3/4 rings on the high side piston , so to convert you would need the high side cylinder head and the piston assembly (you could use the low side piston and unscrew the old high side piston and bolt on the new one)....  The lower cylinder will work but check the bolt pattern for the new head !!
    Some are 4 eqidistant and some are 4 but in a rectangular patern.. The vevor high side piston seal was purchased from Aliexpress, Antlersonline store.. You will need to contact hin and tell him what you want and pay with his extra shipping link..
    When I purchased them he only had 24 and I bought them all..

The one I ordered was $20. It came with lower and high piston with 4 rings. Dang, I thought it be easy just to swap it in. I see the sell the head assembly for $60. Do you know if it will fix on the vevor? Cause I see the SS pipes are different so might not line up. There is also a whole head assembly with both lower and high pressure blocks but it's $109 plus $30 shipping. I should of went with the real Yong Heng. Smh

Just picked up a Vevor for a couple hundo. Only used once. It'll be used as a back up and road trips and only fill guns directly.
Should be here Wed.

Might be worth a shot to see if anyone can turn down the tuxing piston to fit or bore the vevor head to fit the tuxing.

I haven't received my tuxing piston yet. But when I do, I might try to put it on a drill and spin it on a piece of sand paper and make it fit. The hard part is sanding inside the small grove where the rings sit. Be tricky.

Even if you trim down the diamiter of the shaft you still have the diamiter of the seals to contend with, that and there may be a difference in overall length.

I thought about that but the tuxing seals are very pliable and can probably be ground/cut to fit. The length could easily be fixed in a lathe.

I have a Tuxing piston that was converted/turned down so it can be used in my Vevor with 2 of the (modified just as Killfire described) Tuxing split rings.  A member here made it for me and reported that it works great but I have not tried it yet so I can't say.  I still have a couple seals that Cosmic hooked me up with a while back when he was selling his extras but when those get used I'll try the converted piston.
