Abstract

The present invention discloses relates to a sealing structure for push-to-connect tube fitting for finishing a fastening operation at once by inserting the end of a hose with flexibility which can increase an allowable pressure, and in particular to a sealing structure for push-to-connect tube fitting which can enhance air tightness by positioning a backup ring for supporting one side or both sides of an O-ring isntalled to maintain air tightness between a body of the tube fitting and a hose between the body and a hose stopper. When force is transferred to the O-ring in an axial direction due to pulsation or external vibration, the backup ring for supporting one side of the O-ring prevents the O-ring from being moved.
