It delivers a flow rate of 4.5 gallons per hour at 100 PSI and produces a 60 degree spray angle. This nozzle is built with a brass body and a steel orifice disc, giving it solid durability in demanding heating applications. The Monel strainer filter helps keep debris out of the orifice, protecting spray pattern consistency and extending service life. Hollow cone Type A nozzles concentrate droplet distribution on the outside of the cone. This spray pattern supports reliable ignition and low-noise combustion, making it a preferred choice for oil-fired residential burners. HVAC technicians and oil burner service professionals use Type A nozzles on burners that require a hollow cone air pattern. This design works well for throughputs up to 10 gallons per hour, making the 4.5 GPH rating a common fit for many residential boilers and furnaces. The nozzle meets ISO 9001 standards, confirming consistent manufacturing quality. When replacing an oil burner nozzle, matching the flow rate, spray angle, and spray pattern type is critical. Using the wrong nozzle type can cause poor combustion, carbon buildup, smoke, or lockout conditions. The Delavan 4.50-60-A gives technicians a direct replacement option that matches these three parameters precisely. Delavan is a well-known name in oil burner nozzle manufacturing, trusted by heating professionals for accurate spray characteristics and reliable performance across residential heating equipment. This nozzle is rated for operation at 80 degrees F and is compatible with standard 100 PSI burner pump pressure settings found in most residential oil heating systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHollow cone Type A spray pattern concentrates droplets on the outside of the cone for clean ignition and quiet combustion\u003c\/li\u003e\n\u003cli\u003eBrass body and steel orifice disc construction provides durability and resistance to wear in oil heating service\u003c\/li\u003e\n\u003cli\u003eMonel strainer filter protects the orifice from debris, maintaining consistent spray pattern and flow rate\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Delavan 4.50-60-A delivers a precise 4.5 GPH flow rate at a 60 degree hollow cone spray angle, making it a reliable direct replacement nozzle for residential oil burner service.
