It delivers a flow rate of 1.75 gallons per hour at a standard operating pressure of 100 PSI. The 45-degree spray angle produces a solid cone pattern that distributes fuel oil evenly across the combustion chamber. This nozzle is a go-to component for HVAC technicians and oil furnace service professionals who need a reliable, precision-engineered atomizing nozzle for annual tune-ups, nozzle replacements, or new burner installations. The Delavan brand is widely recognized in the heating industry for consistent atomization quality, which directly affects combustion efficiency and heat output. A well-matched nozzle ensures proper fuel-to-air ratio, clean ignition, and reduced carbon buildup in the combustion chamber. The 1.75-45-b features a brass body and a steel orifice disc, giving it the durability and corrosion resistance needed for long-term use in oil-fired furnaces and boilers. The integrated sintered filter screens out particulates that could clog the orifice and cause misfires or incomplete combustion. This nozzle meets ISO 9001 quality standards, confirming consistent manufacturing tolerances across production batches. For service technicians, that consistency means predictable spray performance on every installation. The solid cone spray pattern is particularly effective in residential oil burners where a uniform fuel distribution is needed for stable flame and complete combustion. Whether you are servicing a Beckett, Riello, Carlin, or Wayne burner, the Delavan 1.75-45-b is a standard fit for most residential oil heating equipment requiring a 1.75 GPH, 45-degree, Type B nozzle.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType B solid cone spray pattern for uniform fuel distribution and stable combustion\u003c\/li\u003e\n\u003cli\u003eBrass body with steel orifice disc for durability and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eSintered filter screens particulates to protect the orifice and maintain consistent atomization\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Delavan 1.75-45-b delivers precise 1.75 GPH fuel atomization at a 45-degree solid cone angle, meeting ISO 9001 standards for reliable residential oil burner performance.\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: 1.75-45-b\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\u003eSpray Pattern\u003c\/strong\u003e: Type B, Solid Cone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Angle\u003c\/strong\u003e: 45 Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 1.75 GPH\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\u003eMaterial\u003c\/strong\u003e: Brass Body, Steel Orifice Disc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: Sintered\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":51120775299378,"sku":"1.75-45-B","price":19.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304878430.jpg?v=1777739496","url":"https:\/\/voomisupply.com\/products\/delavan-1-75-45-b-1-75-gph-45-degree-b-solid-cone-oil-burner-nozzle","provider":"Voomi Supply","version":"1.0","type":"link"}
