A leak tester for smoke testing an air conditioning refrigerant circuit. The leak tester includes an oil reservoir for containing a supply of oil. A vaporizer unit of the leak tester includes an input side coupled to the oil reservoir to receive oil from the supply of oil. A smoke output of the leak tester is coupled to an output side of the vaporizer unit. A service coupler is provided at an outlet end of the smoke output, the service coupler adapted to make a sealed connection with a low-pressure service port of the refrigerant circuit. A regulator of the leak tester is operable to set the delivery pressure of the smoke from the smoke output, and the regulator is configured to set the delivery pressure to at least 50 psi.
