PURPOSE: An airtight combination structure of a pipe connector, which provides high airtightness and has a simplified structure, is provided to improve airtightness since an external diameter is shrunk when an O-ring packing is inserted into a taper type packing pressing part. CONSTITUTION: An airtight combination structure of a pipe connector comprises a packing pressing unit, an O-ring packing, and a packing pressing unit(230). The packing pressing unit is formed in the inner side of a packing mounting groove(103). The packing pressing unit has an inclination angle in order to make the inside of the packing pressing unit narrower and strongly press a packing. The O-ring type packing is formed in the front part of the packing pressing unit. The inside diameter of the O-ring type packing is formed larger than the external diameter of the pipe.
