Abstract
According to an embodiment of the present disclosure, a refrigerant pipe fitting, the fitting having a pipe shape with a hollow to connect a pipe, may include an out pipe opening which is opened at one end of the fitting and into which an out pipe is inserted; an inner pipe opening which is opened at the other end of the fitting and into which an inner pipe is inserted to be inserted into the out pipe inside the fitting; a pressing portion which is configured to form a part of an inner surface of the fitting and formed to have a narrower inner diameter as it extends toward the inner pipe opening to press and deform the out pipe to allow the out pipe to connect with the inner pipe in movement of the fitting; and a fastening portion which is formed on the inner surface of the fitting between the pressing portion and the out pipe opening to constrain an end of the out pipe to prevent the fitting from being separated.
