It is the invariable favorite coupling of hydraulic pumps. Thanks to its tight teeth, it provides great ease of assembly. It is not suitable for vibration because the plastic sleeve is rigid and transmits vibration to the engine. When the elastic part is broken, the coupling does not break, the system stops, the elastic sleeve is changed and the working continues.
