Compared to standard fittings, these fittings are considerably shorter, which makes tube cleaning with bends easier. Another advantage is the fact that the crimping of the sleeve only negligibly enlarges the hose OD. As a result, hose types with a larger inner diameter permitting higher volumetric flow can be used.
