Delavan 00120-90a1 Oil Burner Nozzle 1.20 Gph 90 Degree

Product Description

The DELAVAN 00120-90a1 is a Type A hollow-cone oil burner nozzle rated at 1.20 GPH with a 90-degree spray angle. It is designed for residential oil-fired heating systems where a hollow-cone air pattern is required. The brass body and steel orifice disc provide durability under continuous service conditions. A sintered filter screens contaminants before they reach the orifice. This nozzle operates at a rated pressure of 100 psi and is suited for throughputs up to 2.00 GPH. Licensed HVAC technicians and oil burner service techs install this component as part of routine burner maintenance or performance tuning.

This nozzle is intended for residential oil burner applications. The hollow-cone spray pattern concentrates droplet distribution on the outer edge of the cone, which promotes reliable ignition and low-noise combustion. It is a direct-fit nozzle for oil burners that call for a Type A hollow-cone configuration at a 90-degree angle and 1.20 GPH flow rate. It is well suited for systems where a clean, consistent spray pattern is critical to combustion efficiency and heat exchanger protection.

Key Features

• Type A hollow-cone spray pattern concentrates droplets at the outer cone edge for stable ignition
• 1.20 GPH flow rate at 100 psi rated operating pressure
• 90-degree spray angle for burners requiring wide-pattern atomization
• Brass body with steel orifice disc for corrosion resistance and dimensional stability
• Sintered filter integrated into the nozzle assembly for contaminant protection
• Manufactured under ISO 9001 quality standards

Compatibility

Designed as an OEM-style replacement nozzle for residential oil burners requiring a Type A hollow-cone configuration with a 90-degree spray angle and 1.20 GPH flow rate at 100 psi.

Installation Notes

Oil burner nozzles are installed and replaced by licensed oil burner technicians or qualified HVAC service professionals. Always shut down the burner and allow the system to cool before removing the nozzle assembly. Use an appropriate nozzle wrench to avoid damaging the brass body or nozzle adapter. Follow local codes and manufacturer service procedures when setting combustion air and verifying spray pattern after installation.
