Number 12 hydraulic hose typically refers to a hose with an inside diameter of 3/4 inch. Hydraulic hoses are sized based on their internal diameter, and the number 12 corresponds to the standard dash size system used in the industry, where each dash size represents 1/16 of an inch. Therefore, a dash 12 hose has an internal diameter of 12/16 inches, or 3/4 inch.
