CPC Quick Disconnect O-rings

[beerocracy]

Has anyone ordered the O-rings from McMaster Carr for the CPC quick-disconnects? My brewing sculpture uses them and I don't want to be screwed on brew-day if one wears out so I'd like to place a bulk-order of replacement O-rings. I've ordered kegging O-rings from MMC so I'm sure they carry the right one but am not sure the correct part number to order.

Thanks
David
