It atomizes fuel oil into a fine, evenly distributed spray pattern concentrated at the outer edge of the cone, promoting stable ignition and low-noise combustion. The Type A hollow cone design is engineered for oil burners with a hollow cone air pattern and is suitable for fuel throughputs up to 2.00 GPH. Installation is performed by licensed oil burner technicians as part of routine annual service or combustion system repair.\u003c\/p\u003e\n\u003cp\u003eThe 0.75-90-A is used in residential and light commercial oil-fired heating systems equipped with pressure-atomizing gun-type burners. The hollow cone spray pattern is matched to burners that produce a corresponding hollow cone air pattern, ensuring proper fuel-air mixing at the combustion head. This nozzle is appropriate for systems requiring a 0.75 GPH firing rate at standard operating pressure. The red vial identification simplifies nozzle selection and verification during service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHollow cone Type A spray pattern concentrates droplets at the outer edge of the cone for stable ignition\u003c\/li\u003e\n  \u003cli\u003e0.75 GPH flow rate at 100 psi operating pressure\u003c\/li\u003e\n  \u003cli\u003e90-degree spray angle suited to hollow cone air pattern burners\u003c\/li\u003e\n  \u003cli\u003eCompatible with fuel throughputs up to 2.00 GPH in the hollow cone nozzle category\u003c\/li\u003e\n  \u003cli\u003eRed vial color coding for quick identification and replacement verification\u003c\/li\u003e\n  \u003cli\u003eEngineered for low-noise combustion characteristics\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement nozzle for oil-fired pressure-atomizing gun burners that require a hollow cone air pattern and a 0.75 GPH firing rate at 90 degrees.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eOil burner nozzles are serviced by qualified oil heat technicians and should be replaced during annual tune-up or whenever combustion analysis indicates degraded performance. Always shut down the burner and allow the system to cool before removing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the nozzle adapter or electrodes. Verify firing rate, spray angle, and spray pattern type against the burner manufacturer specifications before installing a replacement nozzle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 0.75 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: Hollow Cone (Type A)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Pressure\u003c\/strong\u003e: 100 psi\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\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: 0.75-90-A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51284153008434,"sku":"0.75-90-A","price":17.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278090.jpg?v=1781069905","url":"https:\/\/voomisupply.com\/products\/delavan-0-75-90-a-oil-burner-nozzle-0-75-gph-90-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
