PROBLEM TO BE SOLVED: To provide a fitting for coupling a capillary to another component of a fluid device.SOLUTION: A fitting comprises: a ferrule 106 configured for enclosing a front part of a capillary 102 and for contributing to fluidic sealing between the fitting 100 and another component; a ferrule chuck 108 configured for enclosing a back part of the capillary 102; a housing 104 configured for accommodating at least a part of the ferrule chuck 108 and for pushing the ferrule chuck 108 against the ferrule 106; and a microstructure 110 formed as multiple microprotrusions 120 on at least a part of a surface of the ferrule chuck 108 for generating, upon tightening the fitting 100 at the other component, a form fit with the enclosed back part of the capillary 102 over a contact area between the ferrule chuck 108 and the capillary 102. |
