Abstract:
A fitting element (100), in particular for an HPLC application (10), is configured for providing a fluidic coupling of a tubing (102) to a fluidic device (103). The fitting element (100) comprises a gripping piece (108) to exert - upon coupling of the tubing (102) to the fluidic device (103) - a grip force (G) between the fitting element (100) and the tubing (102). The gripping piece (108) comprises a hydraulic element (170) configured to transform an axial force (S) into a hydraulic pressure (P) within the hydraulic element (170). The hydraulic pressure (P) in the hydraulic element (170) causes the grip force (G).

The inlay (210) protrudes over the front side (146), at least before coupling of the tubing (102) to the fluidic device (103). Upon coupling of the tubing (102) to the fluidic device (103), the front side (146) is fitted to the fluidic device (103) for connecting a fluid path (410) of the tubing (102) to a fluid path (420) of the fluidic device (103), and the inlay (210) provides a sealing of the fluid path (410, 420) of the tubing (102) and the fluidic device (103).
