It delivers a flow rate of 4.00 gallons per hour at a spray angle of 70 degrees. HVAC technicians and oil burner service professionals rely on this nozzle for consistent, reliable combustion performance in standard residential oil-fired heating systems.\u003c\/p\u003e\u003cp\u003eThe Solid Cone spray pattern distributes fuel droplets uniformly throughout the complete spray cone. This uniform distribution promotes smooth ignition and efficient combustion, especially in larger residential burners. At flow rates above 8.00 GPH, the spray pattern becomes progressively more hollow, but at 4.00 GPH this nozzle maintains a dense, even distribution that supports stable flame development and clean burner operation.\u003c\/p\u003e\u003cp\u003eThe nozzle body is constructed from brass, which resists corrosion in fuel oil environments and holds up well under repeated heating and cooling cycles. The orifice disc is made from steel for precise metering of fuel flow. A Monel strainer is built in to filter contaminants from the fuel before they reach the orifice, protecting spray quality and extending nozzle service life. Monel is a nickel-copper alloy known for its resistance to fuel oil and its durability in high-cycle service conditions.\u003c\/p\u003e\u003cp\u003eThis nozzle is rated for operation at 100 PSI and a temperature rating of 80 degrees Fahrenheit, meeting standard residential oil burner specifications. It is manufactured under ISO 9001 quality standards, ensuring consistent dimensions and spray performance from unit to unit. The 70-degree spray angle suits a wide range of residential combustion chamber geometries, making this a practical choice for oil burner nozzle replacement and seasonal maintenance work.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType B Solid Cone spray pattern provides uniform droplet distribution at 4.00 GPH flow rate\u003c\/li\u003e\n\u003cli\u003eBrass body and steel orifice disc construction for durability and precise fuel metering\u003c\/li\u003e\n\u003cli\u003eBuilt-in Monel strainer protects the orifice from fuel contaminants\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Delavan 4.00-70-b oil burner nozzle delivers consistent 4.00 GPH flow at a 70-degree spray angle, supporting smooth ignition and efficient combustion in residential oil heating systems.
