Delavan Oil nozzle P0065-60W5

The Delavan Oil nozzle P0065-60W5 is a precision consumable part designed to atomize fuel oil into a fine spray for efficient combustion in burners. It has a flow rate of 0.65 GPH (gallons per hour), a spray angle of 60 degrees, and a W (hollow) spray pattern. This nozzle is compatible with fuel oil and is identified by the article numbers P0065-60W5, 3042042, and 345.892.074. It is an OEM equivalent to part number 3042042.

When selecting a replacement oil nozzle of this type, ensure that the flow rate, spray angle, and spray pattern match the burner's data plate specifications. The thread size must also correspond to the nozzle holder. Verify the fuel type (e.g., light oil) and confirm the nozzle's markings align with the burner's designation before installation.

If an oil nozzle of this kind fails or is incorrectly matched, common symptoms include sooting, pulsation, or unstable ignition. The burner may produce incomplete combustion, leading to excessive smoke or carbon buildup. Regular inspection and replacement of the nozzle as part of maintenance can prevent these issues.
