RLSS 10dbi o-ring

[Psychonaut]

I recently purchased a RLSS 10dbi protein skimmer but seem to have misplaced the o-ring that connects the body to the collection cup. Looks to be about 6” diameter but I’ve been to the Lowe’s and mom-and-pop hardware store and alas, nothing that fits

I’ve tried emailing RLSS but haven’t gotten a reply and it’s been over a week, I’m figuring must be an old company and finding replacement parts could be a challenge.

Does anyone have a heads up on exactly what o-ring id need, or where to find a company that sells enough o-ring variety’s that I’ll be able to find what I need?

Still looking for some guidance on o-ring replacement.

Barring that what DIY can I try to stop the leaking? I tried cutting and taping 2 shorter o-rings with no luck. Tried glueing said o-ring with super glue no luck
