Delavan 00500-80a7 Oil Burner Nozzle 5 Gph 80 Degree

Product Description

The DELAVAN 00500-80a7 is a Type A hollow-cone oil burner nozzle rated at 5 gallons per hour (GPH) with an 80-degree spray angle. It is designed for residential oil-fired burner applications where a hollow-cone air pattern is required. The brass body and steel orifice disc construction deliver consistent atomization, with droplet distribution concentrated on the outer edge of the cone. This geometry promotes reliable ignition and low-noise combustion. A built-in Monel strainer filters fuel before it reaches the orifice, protecting against debris that could disrupt spray pattern or clog the disc. Licensed oil burner technicians install this nozzle as a routine service component.

This nozzle is suited for residential oil-fired heating systems where hollow-cone combustion is specified. It performs at a rated operating pressure of 100 psi and is appropriate for throughputs up to 10 GPH, making the 5 GPH flow rate well within its design envelope. The 80-degree spray angle matches burner head configurations that call for a wide, hollow pattern, which is common in residential forced-air and boiler applications.

Key Features

• Hollow-cone Type A spray pattern concentrates droplets at the outer edge for stable, low-noise combustion

• 80-degree spray angle matches burner heads requiring a wide hollow pattern
• Brass body with steel orifice disc for durability in continuous fuel service
• Monel strainer filters incoming fuel to protect orifice integrity
• Manufactured under ISO 9001 quality standards

Compatibility

Designed as an OEM-style replacement nozzle for residential oil-fired burners requiring a Type A hollow-cone configuration at 5 GPH and an 80-degree spray angle.

Installation Notes

Oil burner nozzle replacement should be performed by a licensed oil burner technician or qualified HVAC service professional. Shut down the burner and allow the fuel supply line to depressurize before removing the old nozzle. Use a properly sized nozzle wrench to avoid damaging the brass body or nozzle adapter. After installation, verify spray pattern, combustion efficiency, and CO levels with appropriate test instruments before returning the system to service.
