Coupling system for connecting tube to female connector in disk or headlamp-cleaning system in automotive, has sealing element with sectional surface whose dimension is greater than that of sectional surface in section containing ring axis

摘要

The system (10) has a connecting tube (12) staying in fluid-connection with a tube (14) and inserted into a female connector (16). A circular sealing element (20) accommodated in an annular groove (12a) in the connecting tube is sealingly attached to an inner circumferential surface (16a) of the connector. A locking connector (18) fixes the tube (12) and the connector to each other in an axial direction. The dimension of a sectional surface of the element is greater than the dimension of a sectional surface received in a radial direction in a section containing a ring axis (X) toward the axis.
