Delavan 00750-80A7 Oil Burner Nozzle 7.5 Gph 80 Degree

Product Description

The DELAVAN 00750-80A7 is a Type A hollow-cone oil burner nozzle rated at 7.5 GPH with an 80-degree spray angle. It is designed for residential oil-fired heating systems where the burner air pattern matches a hollow-cone configuration. The nozzle features a brass body with a steel orifice disc and an integrated Monel strainer, making it a durable, service-ready component. Flow is rated at 100 psi operating pressure. The hollow-cone spray concentrates droplet distribution along the outer edge of the cone, supporting reliable ignition and low-noise combustion at throughputs up to 10.00 GPH. This nozzle is installed by licensed oil-heat technicians during burner service or seasonal maintenance.

The 00750-80A7 is suited for residential oil burners that operate with a hollow-cone air pattern. This includes forced-air furnaces, boilers, and water heaters fired by No. 2 fuel oil. The hollow-cone spray pattern is typically paired with burner heads that require flame concentration toward the outer cone wall for clean combustion. This nozzle is appropriate for throughput applications up to 10.00 GPH and performs at the rated 100 psi nozzle pressure typical of residential burner pump settings.

Key Features

• Type A hollow-cone spray pattern concentrates droplets at the outer cone edge for stable ignition
• 7.5 GPH flow rate at 100 psi rated operating pressure
• 80-degree spray angle for compatibility with matched hollow-cone burner air patterns
• Brass body construction with steel orifice disc for durability in fuel-oil service
• Integrated Monel strainer filters fuel before it reaches the orifice disc
• Manufactured under ISO 9001 quality standards

Compatibility

Designed as an OEM-style replacement nozzle for residential oil burners requiring a Type A hollow-cone spray pattern at 7.5 GPH and 80 degrees.

Installation Notes

Oil burner nozzle replacement is performed by licensed oil-heat or HVAC technicians. Shut down the burner and allow the system to cool before servicing the nozzle assembly. Use an appropriate nozzle wrench to remove and install the nozzle without distorting the nozzle body or adapter. After installation, verify pump pressure, combustion performance, and CO levels using calibrated test equipment per local code and NFPA 31 guidelines.
