It delivers a flow rate of 3.5 gallons per hour at 100 PSI operating pressure. This nozzle is built for burners that require a hollow cone air pattern and works well for fuel throughputs up to 10.00 gallons per hour. HVAC technicians and heating system service pros rely on nozzles like this one to keep oil-fired boilers, furnaces, and heating units running cleanly and efficiently. The Delavan 3.50-60-A features a brass body with a steel orifice disc, giving it durability under the heat and pressure conditions found in typical residential oil burner applications. The 60 degree spray angle produces a wide, even hollow cone spray pattern. This pattern concentrates droplet distribution toward the outside of the cone, which promotes reliable ignition and quiet, low-noise combustion. The built-in Monel strainer filters out contaminants before they reach the orifice, helping protect the nozzle and maintain consistent spray performance over time. The nozzle is rated for operation at 80 degrees F and is manufactured to ISO 9001 quality standards. Proper nozzle selection is critical in oil burner maintenance. A mismatched flow rate or spray angle can cause incomplete combustion, sooting, or excess fuel consumption. Replacing a worn or clogged nozzle with the correct Delavan Type A hollow cone model helps restore system efficiency. This nozzle is a common service part in annual oil burner tune-ups and is compatible with standard residential oil heating equipment. HVAC service technicians, heating contractors, and fuel oil system specialists will find this a reliable, direct-replacement nozzle for hollow cone burner applications.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHollow Cone Type A spray pattern concentrates droplets on the outside of the cone for good ignition and low-noise combustion\u003c\/li\u003e\n\u003cli\u003eBrass body with steel orifice disc provides durability in residential oil burner environments\u003c\/li\u003e\n\u003cli\u003eBuilt-in Monel strainer protects the orifice by filtering contaminants from the fuel supply\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Delavan 3.50-60-A delivers a precise 3.5 GPH flow rate at a 60 degree hollow cone spray angle, meeting ISO 9001 standards for reliable performance in residential oil burner service and maintenance applications.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DELAVAN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3.50-60-A\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Oil Burner Nozzle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Type\u003c\/strong\u003e: Type A, Hollow Cone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 3.5 GPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Angle\u003c\/strong\u003e: 60 Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 100 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 80 Deg F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrifice Disc Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: Monel Strainer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplicable Standard\u003c\/strong\u003e: ISO 9001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51121086529842,"sku":"3.50-60-A","price":23.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304878462.jpg?v=1777747998","url":"https:\/\/voomisupply.com\/products\/delavan-3-50-60-a-3-50-gph-60-degree-hollow-cone-type-a-oil-burner-nozzle","provider":"Voomi Supply","version":"1.0","type":"link"}
