It atomizes fuel oil into a hollow cone spray pattern, concentrating droplet distribution along the outer edge of the cone. This geometry promotes reliable ignition and low-noise combustion at the burner head. The nozzle is constructed with a brass body and steel orifice disc, and includes a Monel strainer for fuel filtration. It is rated to 100 psi operating pressure. Licensed oil burner technicians and HVAC service professionals install this nozzle during routine annual tune-ups or combustion efficiency service calls.\u003c\/p\u003e\u003cp\u003eThis nozzle is suited for residential oil-fired heating applications where a hollow cone air pattern is required at the burner. Hollow Cone Type A nozzles are appropriate for throughputs up to 10.00 GPH, making the 8.5 GPH flow rate a common selection for mid-range residential heating units. It is installed at the end of the fuel delivery assembly inside the blast tube of a residential oil burner. The 70-degree spray angle is selected to match the combustion head geometry of the specific burner being serviced.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHollow Cone Type A spray pattern concentrates droplets on the outer cone edge for stable ignition\u003c\/li\u003e\n\u003cli\u003e8.5 GPH flow rate rated at 100 psi operating pressure\u003c\/li\u003e\n\u003cli\u003e70-degree spray angle for compatibility with matching combustion head geometries\u003c\/li\u003e\n\u003cli\u003eBrass body with steel orifice disc for fuel-oil service durability\u003c\/li\u003e\n\u003cli\u003eIntegrated Monel strainer filters fuel before it reaches the orifice\u003c\/li\u003e\n\u003cli\u003eISO 9001 applicable standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement nozzle for residential oil burners requiring a Hollow Cone Type A nozzle at 8.5 GPH and a 70-degree spray angle rated to 100 psi.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eOil burner nozzle replacement is performed by a licensed oil burner technician or qualified HVAC service professional. Always shut down the burner and isolate electrical power before removing the nozzle assembly. Use a proper nozzle wrench to avoid distorting the nozzle body or the electrode assembly during removal and installation. Verify that the replacement nozzle flow rate, spray angle, and spray pattern match the burner manufacturer specifications before firing the unit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 8.5 GPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Angle\u003c\/strong\u003e: 70 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Pattern\u003c\/strong\u003e: Hollow Cone Type A\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 degrees 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\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: 00850-70A7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51383438999858,"sku":"00850-70A7","price":22.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670727.jpg?v=1782596623","url":"https:\/\/voomisupply.com\/products\/delavan-00850-70a7-oil-burner-nozzle-8-5-gph-70-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
