Delavan Oil nozzle P0065-80W1

The Delavan Oil nozzle P0065-80W1 is a precision fuel oil nozzle with a flow rate of 0.65 GPH and a spray angle of 80 degrees. It features a W spray pattern and is designed for use with fuel oil. The nozzle has a thread size of 1/8 inch NPT or BSP and is categorized as an oil nozzle. It is equivalent to OEM parts 3042043 and 3049040, and is also referenced under article numbers P0065-80W1, 3042043, 3049040, and 345.892.189. This nozzle atomizes fuel oil into a fine spray for efficient combustion in burners.

When selecting a replacement oil nozzle of this type, the flow rate (GPH), spray angle (in degrees), and spray pattern (hollow, solid, or semi-solid cone) must match the burner manufacturer's specification. The thread type should be confirmed as 1/8 inch NPT or BSP, and physical fit must be verified on site. Always check the existing nozzle or the burner data plate for the exact rating before ordering.

A worn or incorrectly matched oil nozzle can cause sooting, pulsation, or unstable ignition. Symptoms may include incomplete combustion, excessive smoke, or difficulty starting the burner. Regular inspection and replacement of the nozzle as part of maintenance can prevent these issues.
