Delavan 80X70B Oil Burner Nozzle 0.80 Gph 70 Degree

Product Description

The DELAVAN 80X70B is an oil burner nozzle rated at 0.80 gallons per hour (GPH) with a 70-degree spray angle and a solid cone pattern. It delivers a dense, full-coverage spray that supports consistent flame stability, smooth ignition, and efficient fuel combustion. The brass body and stainless-steel orifice resist carbon buildup and maintain precise atomization over extended service intervals. At 1.625 inches in length with a 0.75-inch outer diameter and 9/16-24 UNEF threads, it installs as an OEM-style replacement in residential and light commercial oil-fired heating equipment. Licensed oil burner technicians and HVAC service professionals are the primary installers.

The 80X70B is suited for oil-fired furnaces, boilers, and water heaters that require a solid cone spray pattern for complete flame coverage across the combustion chamber. The solid cone designation means fuel droplets are distributed throughout the entire cone volume, not just the outer edge, which is critical for burner heads that depend on full internal flame fill. Applications where consistent fuel-air mixing and flame retention are priorities are the primary use case for this nozzle type.

Compatibility

Designed as an OEM-style replacement nozzle for oil-fired residential and light commercial burners requiring a 0.80 GPH solid cone nozzle with a 70-degree spray angle and 9/16-24 UNEF threads.

Installation Notes

Oil burner nozzle replacement is a task for licensed oil burner technicians or qualified HVAC service professionals. Shut down the burner and allow the system to cool completely before removing the nozzle assembly. Use the correct nozzle wrench to avoid damaging the nozzle adapter or electrodes during removal and installation. After installation, verify ignition timing, combustion air settings, and fuel pressure before returning the system to service.
