I call bull. I never encounter this while using CO2. I've had to re-lube my regs after heavy use in extreme conditions but never has standard use led to failure.
I would be willing to say you didn't oil up every time and depending on how long you've had your marker possibly never re-lube your reg either.
I just checked sundragon for you and no luck for something that specific. I recommend finding the size and type of oring and just order it from an o-ring specialist.
