for size by the I.D. (Inside Diameter) of the hose (or I.D. of the inner tube). This is compared with rigid tubing which is measured by the O.D. (Outside Diameter) of the tubing. To determine the dash size, convert the tubing size (usually a fraction) into 16ths of an inch. The numerator of the fraction is then the dash size of the tubing or hose.
