The hollow-cone spray pattern concentrates droplet distribution along the outer edge of the cone, which promotes reliable ignition and low-noise combustion. Constructed with a brass body and a steel orifice disc, this nozzle is designed for continuous service at up to 100 psi operating pressure. An integrated Monel strainer filters the fuel supply before it reaches the orifice, protecting the disc from particulate contamination. HVAC and oil burner technicians install this nozzle as a routine maintenance or service replacement component.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is intended for residential oil burner applications where a hollow-cone air pattern is required and throughput falls within the range of up to 10.00 GPH. Hollow-cone Type A nozzles are commonly paired with burners that generate a matching hollow-cone combustion air pattern. Proper nozzle selection by spray angle, flow rate, and cone type is critical to achieving correct flame geometry and combustion efficiency in the specific burner head being serviced.\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 cone edge for stable ignition\u003c\/li\u003e\n  \u003cli\u003e5.5 GPH flow rate suitable for residential oil-fired appliances with throughputs up to 10.00 GPH\u003c\/li\u003e\n  \u003cli\u003e70-degree spray angle matches burner heads requiring a wide hollow-cone pattern\u003c\/li\u003e\n  \u003cli\u003eBrass body and steel orifice disc construction for durability under repeated thermal cycling\u003c\/li\u003e\n  \u003cli\u003eIntegrated Monel strainer protects the orifice from fuel-borne particulates\u003c\/li\u003e\n  \u003cli\u003eRated to 100 psi operating pressure in residential 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 oil burners requiring a Type A hollow-cone spray pattern at 5.5 GPH and a 70-degree angle.

Always shut down the burner and allow the oil supply system to depressurize before removing the existing nozzle. Use an appropriately sized nozzle wrench to avoid damaging the nozzle adapter or electrodes during removal and installation. Follow the burner manufacturer service documentation and applicable local codes for combustion setup after nozzle replacement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Oil Burner Nozzle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCone Type\u003c\/strong\u003e: Type A, Hollow Cone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 5.5 GPH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpray Angle\u003c\/strong\u003e: 70 degrees\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 degrees 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: Monel Strainer\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\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: 00550-70A7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51384008442162,"sku":"00550-70A7","price":17.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670742.jpg?v=1782614931","url":"https:\/\/voomisupply.com\/products\/delavan-00550-70a7-oil-burner-nozzle-5-5-gph-70-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
