It is designed for use in residential and light commercial oil-fired heating systems where consistent atomization and reliable ignition are required. The Type B solid cone pattern distributes droplets uniformly throughout the full spray cone, making it well-suited for larger burner heads that demand even heat distribution across the combustion chamber. HVAC and oil burner service technicians install this nozzle as part of routine annual tune-ups or as a direct replacement during combustion troubleshooting.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is appropriate for oil-fired furnaces, boilers, and water heaters that require a solid cone spray pattern at higher flow rates. The Type B classification produces a progressively more hollow spray pattern at flow rates above 8.00 GPH, but at 1.35 GPH it delivers a consistent, uniform cone that supports smooth ignition and efficient combustion. It is identified by a blue vial color code for quick field identification during nozzle selection and replacement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.35 GPH flow rate for precise fuel delivery in oil-fired heating equipment\u003c\/li\u003e\n  \u003cli\u003e90-degree spray angle suits burner heads requiring a wide combustion pattern\u003c\/li\u003e\n  \u003cli\u003eSolid cone Type B pattern distributes droplets uniformly throughout the full spray zone\u003c\/li\u003e\n  \u003cli\u003eRated at 100 psi operating pressure\u003c\/li\u003e\n  \u003cli\u003eBlue vial color coding allows fast, accurate nozzle identification in the field\u003c\/li\u003e\n  \u003cli\u003eSupports smooth ignition and efficient combustion, particularly in larger burners\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement nozzle for oil burner assemblies requiring a 1.35 GPH, 90-degree, solid cone Type B nozzle at 100 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eOil burner nozzle replacement is performed by licensed HVAC or oil burner service technicians. Always shut down the burner and allow the system to cool before accessing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the electrode assembly or nozzle adapter. Nozzle replacement is typically part of an annual oil burner tune-up and should be accompanied by a combustion efficiency check per NFPA 31 guidelines.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 1.35 GPH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpray Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Pressure\u003c\/strong\u003e: 100 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpray Pattern\u003c\/strong\u003e: Solid Cone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Type\u003c\/strong\u003e: Type B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVial Color Code\u003c\/strong\u003e: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Oil Burner\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1.35-90-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51284141277490,"sku":"1.35-90-B","price":17.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277481.jpg?v=1781069629","url":"https:\/\/voomisupply.com\/products\/delavan-1-35-90-b-oil-burner-nozzle-1-35-gph-90-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
