In the process of nut tightening one and a quarter turn, the following designed action is completed in the tube fittings.
1.By mechanical thread propulsion, the sleeve nut moves forward to push the rear sleeve forward, while the rear sleeve pushes the front sleeve forward.
2.The tip of the pipe fitting body extrudes inward to the front sleeve.
3.The front sleeve eliminates the tolerance between its inner diameter and the outer diameter of the pipe.
4.With the advance of the rear sleeve, the front sleeve moves forward and inward, and the rear end lifts to form a seal with the inclined plane of the fitting body.
5.With the larger deformation of the pipe and the increase of the contact surface between the body slope and the front sleeve, the greater resistance forces the rear sleeve to move inward, thus forming a second strong support on the pipe.
6.After the sleeve nut is tightened one and a quarter turns, it advances 1/16inch (1.52mm), and the hose fitting completes the sealing and holding function of the pipe.
