Hi Dave The larger the gage number the smaller the inner diameter. There is a nice chart relating color code, gage, ID and OD in the EFD Catalog. They don't list a web address but their phone is 800/556-3484. Email me if a fax copy would help John Thorup

Thanks John. You�re correct. I�ve seen tables like that. poorly stated, what I was wondering was: * Is there a calculation that relates the gauge and the inner diameter ... OR * Is that relationship similar to wire gauge and wire diameter.

I think the latter.

yeah, stands to reason it wouldn't be that simple. The latter seems to be the case with the common theme being "arbitrary". Have a look at the link below. I hope it helps. John Thorup
