I have a Zelos which got some manufacturing debris stuck in the valve of the adjustable regulator. I was able to find some videos on u tube that helped me with 100% disassembly. I could not find anything for the Zelos mine in. 22 as far as parts go , but this is what I did. I removed all the O rings with an o ring pick then went to my local ace hardware store here in Tucson , Az , and there was a guy who helped me with the o rings from a bin labeled gas o rings. We matched up the ones I got by placing then side by side. I also found some belliview spring washers there for useing in the regulator. This was first PCP I ever took apart it was harder to work on than the regular guns I gun smithed. I went to Snowpeak web sight no luck. Checked out the Airgunarcheryfun site but never did talk to Wes I hear he is good guy. Maybe Wes can scoop up some seal packs for the Zelos , or Snowpeak
M60 they do have slight differences.
I'll keep my eye on this thread , and hope we can find some parts.
