Delavan 00055-70b1 Oil Nozzle 0.55 Gph 70 Degree Solid

Product Description

The DELAVAN 00055-70b1 is a solid-spray oil burner nozzle rated at 0.55 gallons per hour (GPH) with a 70-degree spray angle. It atomizes fuel oil at the burner head, converting liquid fuel into a fine mist for efficient combustion in residential and light-commercial oil-fired heating systems. The solid spray pattern delivers a concentrated, even distribution well suited to the combustion chamber geometries that call for that cone shape. Licensed oil burner technicians and HVAC service professionals install this nozzle as part of routine annual tune-ups or when replacing a fouled or worn nozzle.

This nozzle is used in oil-fired furnaces, boilers, and water heaters equipped with pressure-atomizing gun-type burners. At 0.55 GPH, it is sized for lower-output heating appliances where precise fuel delivery is critical to combustion efficiency and emissions compliance. The solid B-type spray pattern is commonly specified for shorter, wider combustion chambers. It is a direct-fit replacement style nozzle compatible with standard threaded burner nozzle adapters found on most gun-type oil burners.

Key Features

• 0.55 GPH flow rate for lower-output oil-fired heating systems
• 70-degree spray angle matched to specific combustion chamber geometries
• Solid (B-type) spray pattern for concentrated, even fuel atomization
• Standard threaded body fits most gun-type pressure-atomizing oil burners
• Designed for annual replacement as part of routine oil burner service

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 call for a 0.55 GPH, 70-degree solid spray pattern.

Installation Notes

Installation should be performed by a licensed oil burner technician or qualified HVAC service professional. Shut down the burner and allow the combustion chamber to cool completely before servicing the nozzle. Use a proper nozzle wrench to remove and install the nozzle without damaging the adapter or supply tube. Always verify the replacement nozzle GPH rating, spray angle, and spray pattern match the appliance manufacturer specification before firing the system.
