The utility model discloses a gas resistance device, and particularly relates to a gas resistance device applicable to gas chromatograph, and belongs to the technical field of analysis and test instruments. The gas resistance device is simple in structure, easy to manufacture, convenient to mount, steady in performance and low in cost, and can be used for improving the stability and the accuracy of the whole instrument. A gasket (15) is sleeved by a section of elastic quartz capillary tube (14) is adopted, the middle part of the capillary tube (14), one end of the capillary tube (14) is assembled in an inner hole 2(10) from an inner screw hole (13) of a female sheath (7), the other end of the capillary tube (14) is assembled in an inner hole 1(4) of a male sheath (1), and the gasket (15) is tightly screwed into an inner screw hole (13) of the female sheath (7). For the same gas resistance, the capillary tube (14) with same length is cut and assembled; and for the different gas resistances, the capillary tube (14) with different length is cut and assembled.
