Easy way to remem is the part that touches the other piece is where it gets measured. The "OD" of the hard fuel line touches the "ID" of the neoprene line live every 24 hour block of time like it's your last day on earth

The wall thickness is the "schedule" and probably has to do with a pressure rating because it increases as pipe diameter increases. For example, 1" pipe is 1.315" OD. Schedule 40 wall thickness is 0.133". Schedule 80 is 0.179". 4" pipe is 4.500" diameter. Schedule 40 wall thickness is 0.237" Schedule 80 is 0.337". Over 12" diameter, pipe is OD x wall thickness. Metallic tubing is OD x wall thickness. It's handy to have a couple of books around when you're doing this stuff. R. Last edited by dogdays; 02/15/12 12:31 PM.

In addition to the concept of schedule there is also a 'Standard' (STD) weight which for the most part is schedule 40 up to 12". Larger STD sizes have a constant wall thickness of 0.375". There is an 'Extra Strong' (XS) which is usually schedule 80 up to about 8" before it changes. There is also an "Double Extra Strong' (XXS) which usually has a thicker wall than schedule 160 up to about 8". And dogdays is right, up to 10", Schedule 40 ID is the nominal ID of the pipe. 12" is an oddball. 14" and above the OD of the pipe is nominal size. Can you tell I do this for a living?
