The numbers on hydraulic fittings represent the size and thread of the fitting. The first number indicates the size of the fitting's hole (in sixteenths of an inch), while the second number indicates the thread size (in threads per inch). This information was found on the Hose & Fittings, Etc. website, specifically in the "Understanding Hydraulic Hose Fittings" section.
