Oil Filter sealing ring dimensions

[Jasper013]

Would anyone happen to know the dimensions of the oil filter head/ filter canister sealing ring?
The OEM filter kits that SNG supply come with two sealing rings and I just want to make sure I'm using the correct one!
Both rings have the same circumference and same thickness, but one is slightly wider/ deeper than the other.
Any reason for two different rings being supplied? Or is it a case of 'use the one that fits the best'

Have looked through the tech data etc but cant find the info.

Thanks in advance.

On my car the fat one won’t fit. The thin one seals just fine.

Thanks Steve.
Had spotted that thread. I'm sure its the thinner one I've always fitted before.

Thanks. That's what I've found previously as well.
Getting ready to crawl under and unleash the black stuff (think at best, I've only ever managed to capture about 85% of the oil, rest ends up on me, the floor ……... ).
