The Type A hollow cone design concentrates droplet distribution along the outside of the spray cone, which promotes reliable ignition and low-noise combustion. This nozzle is identified by a red vial for quick field identification. It is installed by HVAC and oil burner service technicians during routine maintenance, nozzle replacement, or combustion tune-up procedures on residential and light commercial oil-fired heating equipment.\u003c\/p\u003e\u003cp\u003eThe 1.25-70-A is suited for oil burner applications requiring a hollow cone air pattern and fuel throughputs up to 2.00 GPH. The 70-degree spray angle makes it appropriate for burner head geometries that call for a moderate spread pattern. It is a direct-fit nozzle for service calls where the existing nozzle matches the 1.25 GPH, 70-degree, Type A hollow cone specification. Annual nozzle replacement is standard practice during oil burner tune-ups to maintain combustion efficiency and minimize soot buildup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.25 GPH flow rate at 100 psi operating pressure\u003c\/li\u003e\n\u003cli\u003e70-degree hollow cone spray angle for compatible burner head geometries\u003c\/li\u003e\n\u003cli\u003eType A hollow cone pattern concentrates droplets at the outer edge of the cone for stable ignition\u003c\/li\u003e\n\u003cli\u003eSupports throughputs up to 2.00 GPH within the hollow cone A-nozzle family\u003c\/li\u003e\n\u003cli\u003eRed vial color coding for fast field identification during service\u003c\/li\u003e\n\u003cli\u003eLow-noise combustion characteristics due to controlled droplet distribution\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for oil burners that require a hollow cone air pattern and a Type A nozzle with a 1.25 GPH rating at 70 degrees.

Always shut down the burner and allow the combustion chamber to cool before accessing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the nozzle adapter or electrodes. Verify burner pump pressure with a gauge before startup to confirm operation at the rated 100 psi.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 1.25 GPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Angle\u003c\/strong\u003e: 70 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: Hollow Cone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Type\u003c\/strong\u003e: Type A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVial Color\u003c\/strong\u003e: Red\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Throughput\u003c\/strong\u003e: 2.00 GPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Oil Burner\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: 1.25-70-A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51283969966386,"sku":"1.25-70-A","price":17.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277482.jpg?v=1781064565","url":"https:\/\/voomisupply.com\/products\/delavan-1-25-70-a-oil-burner-nozzle-1-25-gph-70-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
