It delivers a dense, concentrated fuel pattern designed to support strong ignition, stable flame shape, and efficient combustion in oil-fired heating equipment. The brass housing and stainless-steel metering components provide corrosion resistance and consistent flow accuracy over extended service cycles. At 1.625 inches in length with a 0.75-inch outer diameter and 9\/16-24 UNEF threads, it installs directly into standard oil burner assemblies. HVAC and oil burner service technicians use this nozzle as an OEM-style replacement to restore rated burner efficiency.\u003c\/p\u003e\n\u003cp\u003eThe 55X80B is suited for residential and light-commercial oil-fired heating systems where a solid-cone spray pattern is specified. The solid-cone designation means fuel is distributed evenly throughout the cone volume, making it appropriate for burners that require a concentrated, fully filled spray for proper combustion. It is commonly installed in forced-air oil furnaces, oil boilers, and oil-fired water heaters that call for a 0.55 GPH flow rate at an 80-degree angle. Always verify the burner manufacturer's nozzle specification before selecting a replacement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid-cone spray pattern delivers a dense, fully filled fuel distribution for concentrated combustion\u003c\/li\u003e\n  \u003cli\u003eRated at 0.55 GPH for precise fuel metering in low-fire residential applications\u003c\/li\u003e\n  \u003cli\u003e80-degree spray angle matches burner head geometry requiring a wide, compact flame\u003c\/li\u003e\n  \u003cli\u003eBrass housing with stainless-steel metering parts for durability and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e9\/16-24 UNEF thread fits standard oil burner nozzle adapters\u003c\/li\u003e\n  \u003cli\u003eOEM-style replacement that restores rated combustion efficiency\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 burners requiring a 0.55 GPH, 80-degree solid-cone spray pattern with 9\/16-24 UNEF threads.

Shut down the burner and allow the system to cool before beginning service. Use a proper nozzle wrench to remove and install the nozzle without damaging the adapter or electrode assembly. After installation, verify combustion performance with a flue gas analyzer and adjust air settings as needed per the burner manufacturer's service instructions.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 0.55 GPH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpray Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpray Pattern\u003c\/strong\u003e: Solid Cone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-24 UNEF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMetering Components\u003c\/strong\u003e: Stainless Steel\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: 55X80B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51346672484658,"sku":"55X80B","price":20.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555388.jpg?v=1782087199","url":"https:\/\/voomisupply.com\/products\/delavan-55x80b-oil-burner-nozzle-0-55-gph-80-degree-solid-cone","provider":"Voomi Supply","version":"1.0","type":"link"}
