Oil burner nozzles atomize fuel oil into a fine mist for efficient ignition and combustion in residential and light commercial heating equipment. The semisolid pattern delivers a spray cone that is denser at the outer edges, which suits a range of retention-head and pressure-atomizing burner configurations. This nozzle is installed by licensed HVAC technicians and oil burner service professionals during routine maintenance, combustion tuning, or burner troubleshooting.\u003c\/p\u003e\u003cp\u003eThis nozzle is suited for forced-air oil furnaces, oil boilers, and combination heating appliances that rely on pressure-atomizing burner assemblies. Annual nozzle replacement is standard practice in oil-heat service, making this a high-frequency service part. The 1.75 GPH flow rate and 90-degree semisolid pattern are specified to match particular burner head geometries and firing rates, so selecting the correct combination of GPH, angle, and pattern is critical to achieving proper combustion efficiency and heat output.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.75 GPH flow rate for medium-output oil burner applications\u003c\/li\u003e\n\u003cli\u003e90-degree spray angle for wide combustion chamber coverage\u003c\/li\u003e\n\u003cli\u003eSemisolid spray pattern suits retention-head burner configurations\u003c\/li\u003e\n\u003cli\u003ePressure-atomizing design promotes efficient fuel-air mixing and ignition\u003c\/li\u003e\n\u003cli\u003eStandard nozzle form factor for straightforward field replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement nozzle for residential and light commercial oil-fired heating equipment using pressure-atomizing burner assemblies with a 1.75 GPH firing rate and 90-degree semisolid spray requirement.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eOil burner nozzle replacement should be performed by a qualified oil-heat technician. Always shut down the burner and allow the system to cool before servicing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the nozzle adapter or electrodes, and never over-tighten. After replacement, verify combustion performance with a flue-gas analyzer to confirm proper CO2, oxygen, and smoke readings per NFPA 31 guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 1.75 GPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Pattern\u003c\/strong\u003e: Semisolid\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: 00175-90w1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51468609454386,"sku":"00175-90W1","price":17.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945704.jpg?v=1783918917","url":"https:\/\/voomisupply.com\/products\/delavan-00175-90w1-oil-burner-nozzle-1-75-gph-90-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
