This nozzle delivers a flow rate of 1.5 GPH at a rated pressure of 100 PSI, making it well suited for smaller residential oil-fired boilers and furnaces. The 70-degree spray angle produces a hollow cone spray pattern, concentrating droplet distribution along the outer edge of the cone. This design promotes reliable ignition, stable flame establishment, and low-noise combustion during normal burner operation. HVAC technicians and heating system service professionals rely on Delavan nozzles as an industry standard for oil burner maintenance and replacement work. The Type A hollow cone pattern is specifically recommended for burners that use a corresponding hollow cone air pattern and for throughput applications up to 10.00 GPH. At 1.5 GPH, this nozzle falls well within that operating range, giving technicians a dependable option for low-to-mid output residential heating units. The nozzle body is constructed from brass, which offers corrosion resistance and durability in the presence of heating oil. The orifice disc is made from steel, providing the dimensional stability needed to maintain consistent spray geometry over extended service cycles. A sintered filter is integrated into the nozzle assembly to help trap particulates before they reach the orifice, protecting spray pattern integrity and reducing the risk of nozzle fouling. This product conforms to ISO 9001 quality standards, ensuring consistent manufacturing tolerances. Whether you are performing an annual tune-up, responding to a no-heat call, or completing a burner conversion, the Delavan 1.50-70-A is a direct-fit replacement nozzle for compatible residential oil burner applications.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType A Hollow Cone spray pattern concentrates droplets at the outer cone edge for reliable ignition and quiet combustion\u003c\/li\u003e\n\u003cli\u003eBrass body and steel orifice disc construction provide durability and consistent spray geometry in oil burner environments\u003c\/li\u003e\n\u003cli\u003eIntegrated sintered filter protects the orifice from particulate contamination and helps maintain long-term nozzle performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Delavan 1.50-70-A delivers a precise 1.5 GPH flow rate at a 70-degree hollow cone angle, meeting ISO 9001 standards for quality and consistency in residential oil burner service applications.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\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: 1.50-70-A\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Oil Burner Nozzle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Type\u003c\/strong\u003e: Type A, Hollow Cone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 1.5 GPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Angle\u003c\/strong\u003e: 70 Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 100 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 80 Deg F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrifice Disc Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: Sintered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplicable Standard\u003c\/strong\u003e: ISO 9001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51121110876466,"sku":"1.50-70-A","price":19.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304881949.jpg?v=1777748693","url":"https:\/\/voomisupply.com\/products\/delavan-1-50-70-a-1-5-gph-70-degree-type-a-hollow-cone-oil-burner-nozzle","provider":"Voomi Supply","version":"1.0","type":"link"}
