1. The number represents the diameter
First of all, let's be clear: the number on the rubber hose represents the diameter of the hose, which is usually expressed in millimeters (mm). For example, if a rubber hose is marked with the number "6", it means that the diameter of the rubber hose is 6 mm.
Second, the number represents the wall thickness
In some cases, the number marked on the rubber hose does not represent the diameter of the hose, but rather the wall thickness of the hose. For example, a rubber hose is marked with the number "5×2", where "5" represents the outer diameter of the hose and "2" represents the wall thickness of the hose, which means that the inner diameter of the hose is 3 mm.
3. Figures may be incorrect
It should be noted that the number on the rubber hose is not absolutely accurate and there may be some errors, so when choosing the right hose, it is best to use the actual measurement.
Fourth, how to choose the right hose
There are several factors to consider when choosing the right rubber hose, including operating pressure, operating temperature, media nature, and more. When choosing a hose, you need to understand the relevant parameters and choose according to the actual needs.
