it does look like this machine brand uses 'viton' and ... I"m thinking the oring simply disintegrated over time. (May have been 10 years, may be 5.) Not shaven off.Looks like silicone or viton, but orings don't normally look all shaved like that unless it happens upon installation.
some guy on the machine internet forum says "changed orings multiple times. Viton seem to wear out faster"
