It delivers a flow rate of 1.65 gallons per hour at a 70 degree spray angle with a B solid spray pattern. HVAC technicians and heating system installers rely on this type of nozzle to atomize fuel oil into a fine mist, allowing for clean and efficient combustion inside the burner chamber. The correct nozzle specification directly affects heat output, combustion efficiency, and overall system performance. Choosing the right flow rate, angle, and spray pattern is critical during seasonal tune-ups, burner replacements, and oil furnace or boiler servicing. The 1.65 GPH flow rate makes this nozzle well suited for mid-range oil-fired appliances that require precise fuel delivery. The 70 degree spray angle produces a wide cone that distributes atomized fuel evenly across the combustion chamber, promoting thorough mixing with combustion air. The B or solid spray pattern provides a uniform distribution of fuel droplets throughout the entire cone, which helps reduce soot buildup and supports stable flame formation. Delavan is a well-known manufacturer of oil burner nozzles trusted by heating professionals across North America. Their nozzles are engineered to meet the demands of field service work, including consistent sizing, durable construction, and reliable atomization performance across a wide range of operating pressures. This nozzle is a direct replacement for applications calling for a 1.65 GPH, 70 degree, solid cone specification. It is compatible with standard residential oil burners including those used with Beckett, Riello, Carlin, and similar burner brands. HVAC technicians should always verify the nozzle rating on the burner nameplate or service manual before replacing to ensure proper combustion and safe system operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFlow rate of 1.65 gallons per hour for precise fuel delivery in oil-fired heating systems\u003c\/li\u003e\n\u003cli\u003e70 degree spray angle for wide, even fuel distribution across the combustion chamber\u003c\/li\u003e\n\u003cli\u003eB solid spray pattern promotes stable flame and reduces carbon and soot deposits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Delavan 1.65-70-b solid cone oil burner nozzle delivers accurate fuel atomization at 1.65 GPH with a 70 degree angle, making it a reliable replacement nozzle for residential and light commercial oil heating systems.\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: 1.65-70-b\u003c\/li\u003e\n\u003c\/ul\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: 70 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Pattern\u003c\/strong\u003e: B Solid\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51121041867058,"sku":"1.65-70-B","price":19.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304878407.png?v=1777746735","url":"https:\/\/voomisupply.com\/products\/delavan-1-65-70-b-70-degree-1-65-gph-b-solid-oil-burner-nozzle","provider":"Voomi Supply","version":"1.0","type":"link"}
