Anyone recognize this O-ring?

Anyone recognize this O-ring I found down in my Apex? As you can see about 1" diameter. Hopefully nothing too important lol
Thanks.

I was going to say it's the o-ring for the oil dipstick but they are orange in color; at least they are on my 08 and 18 Apex. Therefore, I am going to suggest it's the o-ring for the oil pickup screen that's located at the bottom of the oil tank:

Could still be for the dipstick as my Attak had a black O ring that size. Its not uncommon to drop that dipstick O ring down into the abiss. I actually have zip tied a few spar O rings by my oil tank filler in case I need one.
