The website on top of the piston is in Cyrillic, but located in Paraguay, but an image search for "piston ring pliers" yields numerous sources for purchase, depending on where you're located: https://duckduckgo.com/?t=ffsb&q=pis...ages&ia=images

I have a set of three made by Gedore in Germany. They work great but you would not want to expand a ring more than a few thou over piston diameter.
