PURPOSE: A pressure gauge for testing refrigerant pipes in an airconditioner is provided to allow a user to easily check the scale part as the scale part set in the desired direction is thread-coupled to an end of a low pressure refrigerant pipe. CONSTITUTION: A pressure gauge for testing refrigerant pipes in an airconditioner comprises a high pressure refrigerant pipe(10a), a low pressure refrigerant pipe(10b), a joint box, a multi-joint member(30) and insert socket parts(40a,40b). The high and the lower pressure refrigerant pipe are connected to an outdoor unit and an indoor unit of the air conditioner to circulate refrigerant. The joint box contains the high and the lower pressure refrigerant pipe. The multi-joint member is attached to a side of the joint box and passed by one side of the high and the lower pressure refrigerant pipe. The insert socket parts are connected to the high and the lower pressure refrigerant pipe passing through the multi-joint member.
