PURPOSE: A refrigerant injection pipe sealing apparatus is provided to reduce sealing processes and waste of raw material, and minimize refrigerant gas leakage. CONSTITUTION: A compressor(100) is provided with a refrigerant by a coupling(300) through a refrigerant injection pipe(101), and a press(200) is arranged to allow a seesaw-like operating member(203) interlocked with an inner piston(202) of a cylinder(201) to press the entrance of the refrigerant injection pipe. A filler material(10) is inserted into the refrigerant injection pipe, and a heating wire(20) is arranged in the seesaw-like operating member of the press, thus allowing the filler material to be melted simultaneously with the pressing action of the seesaw-like operating member. Air pressure supply nipples(204,205) for driving the inner piston of the cylinder are installed in the front portion and rear portion of the cylinder.
