RE: Tubing size

Original poster: Steve_Westberry@xxxxxxxxxxx 

Tim,
On that same page, look at the asterisk beside "Size" under the heading(s)
"Straigth Lengths," which will give a note toward the bottom of the page.
The 1/4" and 3/8" sizes refered to on these threads indicate the "Tube
Size" as designated on the left column of these pages.

Hi Rich,
Thanks for the reply. If you'll go to
<http://www.mcmaster-dot-com>www.mcmaster-dot-com, page 109, and look at
"Cleaned and Capped Copper Tubing", you'll see what I'm talking about...
