It delivers a flow rate of 0.90 gallons per hour at a standard operating pressure of 100 PSI. The 80-degree spray angle and hollow cone spray pattern work together to produce efficient, even fuel atomization inside the combustion chamber. This nozzle is identified by its red vial, which makes it easy to confirm the correct replacement part during service calls. HVAC technicians and oil burner service professionals rely on this type of nozzle to maintain proper combustion efficiency and system performance. Replacing a worn or clogged oil burner nozzle is one of the most common annual maintenance tasks on fuel oil heating systems. A nozzle in poor condition can cause incomplete combustion, sooting, hard starts, and reduced heating efficiency. The Delavan 0.90-80-a is built to deliver consistent atomization and reliable ignition cycle after cycle. Delavan is a well-established brand in the oil burner nozzle market, known for tight manufacturing tolerances and consistent flow rates. This nozzle fits a wide range of residential oil-fired furnaces, boilers, and water heaters that require a 0.90 GPH hollow cone nozzle. The hollow cone pattern is commonly specified for oil burners with retention head designs, where a defined flame shape improves heat transfer and combustion control. When servicing an oil-fired heating system, always verify the nozzle flow rate, spray angle, and spray pattern against the original equipment manufacturer specifications before installing a replacement. The Delavan 0.90-80-a meets those specifications for a broad range of equipment configurations, making it a go-to choice for heating contractors and service technicians stocking their trucks for the heating season.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFlow rate of 0.90 gallons per hour at 100 PSI operating pressure\u003c\/li\u003e\n\u003cli\u003e80-degree hollow cone spray pattern for efficient fuel atomization\u003c\/li\u003e\n\u003cli\u003eRed vial color coding for fast, accurate identification in the field\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Delavan 0.90-80-a oil burner nozzle delivers precise fuel atomization with a 0.90 GPH flow rate and 80-degree hollow cone spray pattern.
