The present invention discloses a pipefitting and a corresponding assembling structure thereof. The pipefitting has male threads and the corresponding assembling structure has female threads located in positions corresponding to the male threads of the pipefitting such that the pipefitting and the corresponding assembling structure can be assembled together. The improvement of the present invention comprises a first O-ring sleeved onto a front end of the male threads of the pipefitting; a circular section formed on a back end of the male threads; a second O-ring sleeved onto the circular section; and an inner section formed in the corresponding assembling structure in a position corresponding to the circular section of the pipefitting for tightly touching the second O-ring, thereby preventing leakage caused by hydraulic burst pressure inside the corresponding assembling structure.
