        Does anyone have information on the specifications of type M 3/4 inch residential copper water pipe(red label). After buying them at two different places I have found out they have different thickness and different weights. It seems to me the pipe should have the same specs regardless where made.

          3/4″ hard drawn copper tube:

          Maximum OD 0.876″
          Minimum OD 0.874″
          Nominal Wall Thickness 0.032″

          Research ASTM B-88 for actual standards
