More Information
Summary:The present invention relates to a tube fitting which is designed to be easily checked by visual inspection as to whether the nut tightening reaches a reference value. The tube fitting comprises a tube inserted into a body, at least one ferrule disposed around the tube, and a nut tightened onto the body to deform the ferrule for providing a seal between the body and the tube. If the nut is tightened on the body to a reference value, a check ring is detached from the body by a pressing force of the nut such that the coupling state of the nut can be checked.
