That is a common misconception Try taking a ruler to 1/2"
nominal Schedule 40 pipe sometime.
So what's your point? 1/2" sched 40 is .680" OD.

My point is stated in the article. I'll repeat it now. Pipe is
not measured by ID. It is measured by OD and wall thickness.

I think you are confusing mechanical tubing with sched 40 pipe.

No, I am not.

Dear Mr Troll:

The OD for 3/4" schedule 10 pipe is 1.050".
The OD for 3/4" schedule 40 pipe is 1.050".
The OD for 3/4" schedule 80 pipe is 1.050".

The ID's are different for each.
