A hose line and a method for producing the same. The hose line (1) has a hose connection (3) which has a connection piece having a connection nipple. A hose end of a flexible hose (2) is pushed onto the connection nipple. The hose connection (3) also has a crimp sleeve (6) which immovably clamps the hose end between itself and the connection nipple in the longitudinal direction of the nipple. There are at least two tool contact surfaces on the hose connection (3), arranged on opposite sides of the hose connection (3), preferably allocated to each other in pairs and in particular designed as wrench contact surfaces (7). The at least two tool contact surfaces of the hose connection (3), which are allocated to each other in pairs, are on the crimp sleeve (6). A ratio of a length of the crimp sleeve (6) to an outside diameter of the flexible hose is 1.5:1 to 3:1.
A hose line (1, 10) comprising at least one hose connector (3) which has a connection piece (4) with a connection nipple (5), onto which connection nipple (5) a hose end of a flexible hose (2) is pushed, and a crimp sleeve (6) which clamps the hose end between itself and the connection nipple (5) in an immovable manner in a longitudinal direction of the nipple, at least two tool engagement surfaces (7) arranged on the crimp sleeve (6) on opposite sides of the hose connector (3), the at least two tool engagement surfaces (7) are arranged in a portion of the crimp sleeve (6) in which the crimp sleeve (6) fully encases the hose end, and the at least two tool engagement surfaces (7) are configured only as deformations or indentations of the crimp sleeve (6) formed during crimping of the crimp sleeve (6) on the connection piece (4), without molding of the connection nipple (5), and a ratio of a length of the crimp sleeve (6) to an outside diameter of the flexible hose is 1.5:1 to 3:1, and the at least two tool engagement surfaces are defined by flats that are joined by curved sleeve portions of the crimp sleeve in a circumferential direction.
A method for producing a hose line, comprising providing a sleeve-shaped connection piece (4), one sleeve end of which is configured as a connection nipple (5), pushing a hose end of a flexible hose (2) onto the connection nipple (4), securing the hose end onto the connection nipple (4) by crimping a crimp sleeve (6) by deforming the crimp sleeve (6) during crimping, without molding of the connection nipple (5), and forming at least two tool engagement surfaces (7) on opposite sides, with a ratio of a length of the crimp sleeve (6) to an outside diameter of the flexible hose being 1.5:1 to 3:1, and defining the at least two tool engagement surfaces with flats that are joined by curved sleeve portions of the crimp sleeve in a circumferential direction.
