thin vs. thick o-rings?

[sinn98]

tonight i unscrewed all the barbs from my cpu and gpu waterblock, rad, and reservoir for cleaning....

i need to put back on barbs for:

gpu waterblock
cpu waterblock
rad
reservoir

i have:
2 pairs of barbs with thin o-rings
2 pairs of barbs with thick o-rings

i have no idea which go on what or if its even important to distinguish them, but already i had a barb not screw in quite right (these are all same size screws)...

i'm suspecting the thinner barbs go on both waterblocks and the fat ones for the reservoir and rad, but i'm not sure and afraid my carelessness will lead to a leak..

can anyone comment plzthx?

It's hard to tell if we can see some pics.
A mistake to learn from. Always keep them in order when you disassemble.

It also helps to know what waterblocks and radiator you have, they could have different threadings on the barbs which would be another way to tell. The size of the O-ring shouldn't make a difference on barbs.

TDX and Tyee waterblocks, Black Ice rad, as stated in my signature...

think i figured out which go on which anyways...

lessen learned....don't assume any part to be the same no matter how similar they look!
