Delavan 125-60a1 Oil Burner Nozzle 1.25 Gph 60 Degree

Product Description

The DELAVAN 125-60a1 is a Type A hollow cone oil burner nozzle rated at 1.25 gallons per hour (GPH) with a 60-degree spray angle. It meters and atomizes fuel oil into a fine, hollow cone spray pattern for efficient combustion in residential and light commercial oil-fired heating equipment. The hollow cone pattern distributes fuel along the outer edges of the spray envelope, which suits burner heads designed for that specific flame geometry. Licensed oil burner technicians and HVAC service professionals are the typical installers of this nozzle type.

This nozzle is used in oil-fired forced-air furnaces, boilers, and water heaters that require a 1.25 GPH flow rate and a 60-degree hollow cone spray. The Type A designation refers to the internal orifice and swirl chamber design, which affects atomization quality and is a required match spec when selecting a replacement. Always confirm the GPH rating, spray angle, and nozzle type against the appliance manufacturer's service label before installation.

Installation Notes

Oil burner nozzles are serviced by licensed oil burner technicians or qualified HVAC professionals. Shut down the burner and allow the system to cool before replacing the nozzle. Use a nozzle wrench to avoid damaging the adapter or electrodes, and never reuse a removed nozzle. Confirm nozzle specifications against the appliance rating plate before installation, as an incorrect GPH rating, angle, or spray pattern can cause combustion problems or equipment damage.
