Tube Dimension Table


 
The table below shows the outside diameter (O.D.) and inside diameter (I.D.), as well as the wall thickness for various tube sizes. The inside diameter varies according to the wall thickness (.120, .083 or .065 inches).

For example, a 1–1/4 tube size with a .120 inch wall thickness has a 1.250 inch O.D. and a 1.010 inch I.D.
