I see coils of 3/8ths copper tubing. Some are labled where 3/8ths is the inner diameter and some where its the outer diameter.
So, with all the posts on this site debating 3/8ths vs 1/2 inch, are people debating outer diameters or inner?
In other words, I can buy either. I want to know which size the homebrewers have been talking about all these years.
