So this fitting has two different tube OD sizes, a 3/4" and a 1/2"? Just want to make sure I'm understanding that right.

Yes, that's correct. This straight fitting is designed to accommodate both a 3/4" tube OD on one end and a 1/2" tube OD on the other, making it useful for connecting different sized lines.
