Let me write this down first you are probably right and I worked a hard day
today.

7/8 Refrigeration equals.........3/4 Plumbing

I just bought a few hundred refrigeration fittings today too!

My bad, thanks for the correction. My brain is right my hands are stupid
today

Refigeration tubing is ID, Plumbing pipe is sized by OD.

Bob,
Check your references. You have it backwards. Refrigeration tubing (ACR)
is sized by the actual OD. Plumbing & heating tubing is sized by the
nominal I.D. Therefore 1/2" plumbing tubing has an actual OD of 5/8". I
just checked my textbooks to verify this so as not to give
dis-information.
