[Rubber Ring in Heavy Sixer case]

I'm new to this forum and i have just started my first Heavy Sixer refurbish. I soaked the case parts for cleaning and there was a rubber ring floating in the water when I was done. It is approx 1/2 inch in diameter, flat on 1 side and rounded on the other. Is this part of the assembly or just random junk.

 

thanks
