Delavan Oil nozzle P0075-45B1

The Delavan Oil nozzle P0075-45B1 is a precision component designed for oil burners, with a nominal flow rate of 0.75 gallons per hour and a 45-degree spray angle. Its spray pattern type is B, which determines the fuel distribution within the combustion head. This nozzle atomizes fuel into a fine mist for efficient mixing with combustion air. It is identified by manufacturer codes P0075-45B1, 3042056, and 345.892.126.

When selecting a replacement oil nozzle, verify that the flow rate, spray angle, and spray pattern match the burner manufacturer's specification. The nozzle threads into the oil pump or nozzle holder; handle it by the body to avoid damaging the orifice. Do not overtighten, and after installation, check the flame shape and combustion readings to confirm correct operation.

A worn or incorrect oil nozzle can cause sooting, flame instability, or ignition failure. These issues arise when the spray pattern or angle no longer matches the combustion head geometry, leading to incomplete combustion. Inspect the nozzle for clogging or damage if the burner exhibits these symptoms.
