EXAIR’s new 1 NPT Back Blow Air Nozzle has been designed to effectively blow debris and liquids from pipe or hose inside diameters, axle housings, bores, holes, internal threads and other internal part features found in hydraulic cylinders, gear boxes, differential housings and more. An array of holes provide a forceful 360 degree airflow to clear out coolant, chips and light oils from machining processes.
