Recognize this plastic seal?

[kjarrett]

It's about 2.2mm across. Found it in my shop, no idea where it came from and obviously as I have just finished a massive rebuild I'd like to know where it belongs. :!:

It's plastic and in good condition, appears to be a seal of some kind?

Thanks in advance,
