It meters and atomizes fuel oil into a fine, hollow cone spray pattern for efficient combustion in residential and light commercial oil-fired heating equipment. The Type A designation indicates a hollow cone spray pattern, which produces flame shapes suited to specific burner head configurations. Licensed oil burner technicians select nozzles like this one to match burner manufacturer specifications for flow rate, spray angle, and pattern type.\u003c\/p\u003e\u003cp\u003eThis nozzle is used in oil-fired forced-air furnaces, boilers, and water heaters that use a pressure-atomizing gun-type burner. The 1.65 GPH flow rate and 80-degree hollow cone pattern make it appropriate for mid-range firing rate applications where a wide spray angle is required by the burner design. Proper nozzle selection is critical to achieving rated combustion efficiency and minimizing soot, smoke, and off-cycle oil drip.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.65 GPH flow rate for precise fuel metering at rated pump pressure\u003c\/li\u003e\n\u003cli\u003e80-degree spray angle matches burner head and combustion chamber geometry\u003c\/li\u003e\n\u003cli\u003eType A hollow cone spray pattern for compatible burner configurations\u003c\/li\u003e\n\u003cli\u003ePressure-atomizing design for consistent droplet size and clean combustion\u003c\/li\u003e\n\u003cli\u003eStandard nozzle thread for direct replacement in gun-type oil burners\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement nozzle for gun-type pressure-atomizing oil burners requiring a 1.65 GPH, 80-degree, Type A hollow cone nozzle specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eOil burner nozzle replacement is performed by licensed oil burner technicians or qualified HVAC service professionals. Always shut off power to the burner and close the fuel supply valve before servicing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the nozzle body or adapter, and never reuse a removed nozzle. Nozzle replacement should follow the appliance manufacturer's service specifications and applicable local codes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 1.65 GPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Pattern\u003c\/strong\u003e: Hollow Cone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: A\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: 165-80a1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51620868063538,"sku":"165-80A1","price":21.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/delavan_2_beb7705e-e5c8-47ac-87dc-30921b6f8b45.jpg?v=1787347380","url":"https:\/\/voomisupply.com\/products\/delavan-165-80a1-oil-burner-nozzle-1-65-gph-80-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
