Einhell Log Splitter Sealing Ring

I acquired a log splitter that was non functional upon taking it apart, i discovered that the sealing ring was broken, i then went to einhells website to discover that it was not in stock. much to my surprise i then designed this ring using what was left of the original and some extra measurements from the actual hydraulics of the log splitter, note you will need an existing O-ring to put on underneath this but found no issues.It is part number 74 on the einhell websiteEinhell BTLS44
