O ring for miller sanke keg

[Blindsquirrelbrewery]

Im looking for the rubber ring that the "ball" on a miller keg rests against. The main o-ring that you see on the top of the keg. I damaged mine getting to the safety lever, so I can refill the keg. Looked for a while online with no luck on finding replacement parts....
