Delavan 00165-90b1 Oil Nozzle 1.65 Gph 90 Degree Solid

Product Description

The DELAVAN 00165-90b1 is a solid-spray oil burner nozzle rated at 1.65 gallons per hour (GPH) with a 90-degree spray angle. It meters and atomizes fuel oil into the combustion chamber of a residential or light-commercial oil-fired heating appliance. The solid spray pattern delivers a concentrated, symmetrical cone of atomized fuel suited for burner heads that require consistent flame shape and stable combustion. Licensed oil burner technicians and HVAC service professionals install this nozzle as part of routine annual maintenance or burner tune-up service.

This nozzle is used in oil-fired forced-air furnaces, boilers, and water heaters equipped with pressure-atomizing gun-type burners. The 1.65 GPH flow rate and 90-degree solid spray angle match specific burner and heat exchanger configurations where wider spray angles and solid patterns are called for to achieve proper combustion efficiency. It is selected based on the burner manufacturer's nozzle specification chart for the appliance being serviced.

Key Features

• 1.65 GPH flow rate for precise fuel metering at rated pump pressure
• 90-degree spray angle for wide combustion chamber coverage
• Solid spray pattern provides a dense, symmetrical atomization cone
• Standard nozzle body threading compatible with common oil burner nozzle adapters
• Designed for use in pressure-atomizing gun-type oil burners

Compatibility

Designed as an OEM-style replacement nozzle for residential and light-commercial oil-fired furnaces, boilers, and water heaters using pressure-atomizing gun-type burners that specify a 1.65 GPH, 90-degree solid-spray nozzle.

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 system to cool before accessing the nozzle assembly. Use a proper nozzle wrench to remove and install the nozzle without damaging the electrode assembly or nozzle adapter. After installation, verify pump pressure, combustion air settings, and perform a combustion analysis to confirm proper operation before returning the system to service.
