Delavan 00325-90A7 Hollow Cone Nozzle 3.25 Gph 90 Degree

Product Description

The DELAVAN 00325-90A7 is a hollow cone oil burner nozzle rated at 3.25 gallons per hour (GPH) with a 90-degree spray angle. It includes an integrated mesh strainer that filters fuel before atomization, helping maintain consistent spray pattern performance. This nozzle atomizes fuel oil into a fine, hollow cone pattern for efficient combustion in residential and light commercial oil-fired heating equipment. Installation is performed by licensed oil burner technicians during routine nozzle replacement or combustion tune-up service.

This nozzle is suited for oil-fired furnaces, boilers, and water heaters that require a hollow cone spray pattern at a 90-degree angle. The A-type orifice designation indicates a standard hollow cone spray classification, commonly specified in equipment manufacturer service manuals for seasonal nozzle replacement. Technicians select this nozzle when matching OEM combustion specifications on 3.25 GPH burner assemblies.

Key Features

• 3.25 GPH flow rate for precise fuel delivery matching burner specifications
• 90-degree spray angle for broad, efficient combustion chamber coverage
• Hollow cone spray pattern promotes thorough fuel-air mixing
• Integrated mesh strainer filters debris from the fuel supply line before atomization
• A-type orifice classification aligns with standard oil burner service specifications

Compatibility

Designed as an OEM-style replacement nozzle for oil-fired furnaces, boilers, and water heaters requiring a 3.25 GPH hollow cone nozzle with a 90-degree spray angle and A-type orifice.

Installation Notes

Oil burner nozzle replacement is performed by qualified oil burner technicians or licensed HVAC-R service professionals. Shut off the burner and allow the unit to cool before servicing. Use a nozzle wrench to remove and install the nozzle to avoid damaging the nozzle adapter or electrodes. Always verify the replacement nozzle GPH rating, spray angle, and pattern type match the equipment manufacturer specifications before firing the burner.
