It delivers a flow rate of 0.55 gallons per hour at 100 PSI operating pressure. The nozzle produces a hollow cone spray pattern at a 70 degree angle, which is ideal for specific burner head configurations that require a wide, even distribution of fuel. This nozzle is identified by its red vial, which serves as a quick visual reference for technicians during installation and servicing. Oil burner nozzles like the Delavan 0.55-70-A play a critical role in fuel combustion efficiency. They atomize the fuel oil into a fine mist before it enters the combustion chamber. Proper atomization ensures clean, complete burning with minimal soot, smoke, and carbon buildup. Choosing the correct nozzle size, spray angle, and pattern type is essential for maintaining the correct air-to-fuel ratio and keeping heating systems operating within manufacturer specifications. The 0.55 GPH rating makes this nozzle suitable for smaller oil-fired furnaces, boilers, and water heaters where precise fuel metering is required. HVAC technicians and heating system service professionals rely on Delavan nozzles for consistent performance and repeatable spray characteristics. Delavan is a well-established manufacturer in the oil burner nozzle market, known for tight tolerances and reliable flow rates. The hollow cone spray pattern of the 0.55-70-A directs fuel to the outer edges of the spray, leaving the center relatively clear. This pattern works well in burner setups designed to take advantage of this distribution for improved ignition and flame stability. Always replace oil burner nozzles during annual service calls to maintain peak combustion performance and system efficiency.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFlow rate of 0.55 gallons per hour at 100 PSI for precise fuel delivery in smaller oil-fired heating systems\u003c\/li\u003e\n\u003cli\u003e70 degree hollow cone spray pattern provides wide fuel distribution for clean, efficient combustion\u003c\/li\u003e\n\u003cli\u003eRed vial color coding allows for fast, accurate identification during installation and routine maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Delavan 0.55-70-A oil burner nozzle delivers consistent 0.55 GPH fuel flow with a 70 degree hollow cone spray pattern, making it a reliable replacement nozzle for residential oil-fired furnaces, boilers, and water heaters.\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: 0.55-70-A\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: 0.55 GPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Pressure\u003c\/strong\u003e: 100 PSI\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVial Color\u003c\/strong\u003e: Red\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Oil Burner Nozzle\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51120989503794,"sku":"0.55-70-A","price":17.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304878404.jpg?v=1777745156","url":"https:\/\/voomisupply.com\/products\/delavan-0-55-70-a-oil-burner-nozzle-0-55-gph-70-degree-hollow-cone","provider":"Voomi Supply","version":"1.0","type":"link"}
