It atomizes fuel oil into a fine, hollow cone spray pattern, delivering consistent combustion performance in residential and light commercial oil-fired heating equipment. The hollow cone pattern distributes fuel along the outer edge of the spray, which supports stable ignition in burners designed for that spray geometry. Licensed oil burner technicians select this nozzle during routine service, seasonal tune-ups, or combustion efficiency adjustments.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is suited for residential oil furnaces, oil boilers, and water heaters equipped with pressure-atomizing gun-type burners. The 1.35 GPH flow rate and 80-degree angle make it appropriate for mid-range firing rate applications where the burner manufacturer specifies a hollow cone pattern. Always verify the OEM-recommended nozzle specification before installation, as flow rate, spray angle, and spray pattern must match the burner's design requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.35 GPH flow rate for precise fuel delivery at rated firing conditions\u003c\/li\u003e\n  \u003cli\u003e80-degree spray angle for wide combustion chamber coverage\u003c\/li\u003e\n  \u003cli\u003eType A hollow cone spray pattern for stable ignition in compatible burners\u003c\/li\u003e\n  \u003cli\u003ePressure-atomizing design compatible with standard gun-type oil burner assemblies\u003c\/li\u003e\n  \u003cli\u003eDirect replacement nozzle for routine annual oil burner service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement nozzle for residential and light commercial pressure-atomizing oil burners specifying a 1.35 GPH, 80-degree, hollow cone Type A nozzle.

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 reuse a nozzle once it has been fired. Combustion testing with a flue gas analyzer is recommended after any nozzle change to verify CO2, smoke number, and stack temperature are within acceptable limits.\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: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpray Pattern\u003c\/strong\u003e: Hollow Cone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Type\u003c\/strong\u003e: Type A\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: 135-80a1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51619852550450,"sku":"135-80A1","price":21.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/delavan_2_ff1329b4-e1af-46af-99a2-cebe7c763bd2.jpg?v=1787335977","url":"https:\/\/voomisupply.com\/products\/delavan-135-80a1-oil-burner-nozzle-1-35-gph-80-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
