The information running down the length of a hydraulic hose is the called the hose layline.
This is a series of identifiers and details specifying information about the hose, usually for reordering purposes. Just as importantly, however, this information will specify items such as hose diameter, maximum working pressure, temperature range, and more. Take a look at the following chart from Parker with a detailed guide of a layline, and check out the video from Parker as they discuss laylines in detail.
For more in depth information about hydraulic hose laylines, take a look at an article from Parker: Decoding a Hydraulic Hose Layline.
