measurement - How are vacuum hose sizes measured ...
2016-2-11u2002·u2002I'd like to understand how vacuum hose sizes are specified so that I can measure what I have. For example: on my shop vac, the end of the hose measures 2-1/8'ID x 2-1/4'OD, and the end of the attachments measure 2-1/4'ID x 2-1/2'OD. What is the correct way to refer to the size of this hose?
