Delavan 0.70-70-a Oil Burner Nozzle 0.7 Gph 70 Degree Hollow Cone

Product Description

The Delavan 0.70-70-A is an oil burner nozzle built for residential and light commercial heating systems that run on fuel oil. This nozzle delivers a flow rate of 0.7 gallons per hour at a rated operating pressure of 100 PSI. It features a 70-degree spray angle and a hollow cone spray pattern, which makes it well suited for a wide range of oil-fired burner applications including forced air furnaces, boilers, and water heaters. The red vial color code on this nozzle identifies it as a hollow cone type, which helps technicians quickly confirm the correct nozzle during installation or replacement. Proper nozzle selection is critical in oil burner service. The spray angle, flow rate, and spray pattern all affect combustion efficiency, heat output, and emissions. Using the correct nozzle prevents issues like soot buildup, delayed ignition, and poor fuel atomization. The Delavan 0.70-70-A atomizes fuel oil into a fine mist that mixes with air in the combustion chamber. This promotes clean, efficient burning. HVAC technicians and heating contractors rely on Delavan nozzles for their consistent spray geometry and reliable performance across a wide range of burner brands. This nozzle fits standard oil burner nozzle threads and is compatible with most residential oil burners on the market. When servicing an oil heating system, the nozzle should be inspected and typically replaced on an annual basis as part of routine preventive maintenance. Replacing a worn or clogged nozzle restores proper combustion, reduces fuel waste, and helps the system meet efficiency standards. The Delavan 0.70-70-A is a direct replacement option for technicians maintaining oil heat systems that require a 0.7 GPH, 70-degree, hollow cone nozzle.
