Abstract

A tightness-indicating tube fitting is disclosed. The tightness-indicating tube fitting includes a tube inserted into a body, at least one ferrule disposed around the tube, a nut fastened onto the body to deform the ferrule for providing a seal between the body and the tube, and a check ring having a pressure-receiving section protruding from a side of the check ring facing the nut. The pressure-receiving section has an inner diameter part which is provided with a slope. When the nut is fastened onto the body by the amount of nut rotation corresponding to a predetermined length as the nut moves forwards after having made an initial contact with the slope of the pressure-receiving section, a pressing force of the nut acts on the slope and the check ring is detached from the body by a pressing force of the nut such that a fastened state of the nut is checked.
