Delavan 120-80b1 Oil Burner Nozzle 1.2 Gph 80 Degree

Product Description

The DELAVAN 120-80b1 is a Type B solid cone oil burner nozzle rated at 1.2 gallons per hour (GPH) with an 80-degree spray angle. It atomizes fuel oil into a fine, uniform cone pattern for efficient combustion inside residential and light commercial oil-fired heating appliances. The solid cone spray pattern delivers consistent fuel distribution across the full cone area, supporting stable flame establishment and clean burner operation. HVAC technicians and oil burner service professionals install this nozzle as a routine maintenance replacement on standard pressure-gun type oil burners.

This nozzle is suited for oil-fired forced-air furnaces, boilers, and water heaters that operate with a standard fuel unit delivering oil at typical burner pressures. The 80-degree spray angle and 1.2 GPH flow rate make it appropriate for mid-range firing rate applications in residential heating systems. The Type B solid cone designation indicates a spray pattern that concentrates fuel throughout the cone body rather than only at the periphery, which suits a range of combustion chamber geometries commonly found in residential equipment.

Key Features

• 1.2 GPH flow rate for mid-range residential oil burner firing
• 80-degree spray angle for wide combustion chamber coverage
• Type B solid cone pattern for uniform fuel distribution throughout the cone
• Standard replacement nozzle compatible with pressure-gun type oil burners
• Precise atomization supports clean, efficient combustion and reduced sooting

Compatibility

Designed as an OEM-style replacement nozzle for pressure-gun type oil burners in residential and light commercial oil-fired heating equipment requiring a 1.2 GPH, 80-degree, Type B solid cone nozzle.

Installation Notes

Oil burner nozzle replacement is performed by licensed oil burner technicians or qualified HVAC service professionals. Always shut down the burner and disconnect power before servicing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the nozzle body or adapter, and never reuse a nozzle that has been removed from service. Verify the replacement nozzle GPH rating, spray angle, and pattern type match the equipment manufacturer specifications before installation.
