Response to The Spacer, External 2" - 194893 does not come with any o-rings, but, if this is for the Pentair/Pac Fab Nautilus INS DE, INS24, 36, or 48 filter, we do have the bulkhead o-ring (facing the body of the filter) and the o-ring for the other side available.  Be sure to put some lubricant on them to help them seal and last a long time.
