Tube vs Pipe - The Differences Explained in Plain English

Jul 13, 2019 · Tubing. Tubing is usually more expensive than pipe due to tighter manufacturing tolerances. Interestingly, while the stated and measured OD's of tubing are almost exact most of the time, copper tubing generally has a measured OD that is 1/8" larger than stated OD. As such, maybe it should be called copper pipe.
