Delavan 0.75GPH, 60B (1) nozzle

The Delavan 0.75 GPH, 60B (1) nozzle is an oil nozzle, a precision consumable component that atomises fuel oil into a fine spray for complete combustion. Such nozzles are mounted in the burner’s blast tube, where the spray cone must match the combustion head geometry and airflow. The part is identified by its catalogue article 345.892.041 and manufacturer codes P0075-60B1, 3042057, and 345.892.041. For oil nozzles of this class, three parameters determine correct operation: flow rate (here 0.75 GPH, which corresponds to the rated delivery at a reference pressure, typically 7 bar or 100 psi), spray angle (60 degrees), and spray pattern (here designated “B”, which indicates a specific cone type—either solid, hollow, or semi-solid). The burner data plate specifies all three; fitting a nozzle with the right rating but wrong pattern can cause sooting, pulsation, or unstable ignition. When replacing a nozzle of this type, always verify that the GPH, angle, and pattern match the original specification. The thread is standard 1/8” NPT for most domestic and light commercial oil burners.
