Delavan 65-80a1 Oil Burner Nozzle 0.65 Gph 80 Degree

Product Description

The DELAVAN 65-80a1 is a Type A hollow cone oil burner nozzle rated at 0.65 gallons per hour (GPH) with an 80-degree spray angle. It atomizes fuel oil into a fine, hollow cone pattern for efficient combustion in residential and light commercial oil-fired heating equipment. The hollow cone spray pattern distributes fuel at the outer edges of the cone, which suits certain burner head designs that require concentrated flame shaping. Licensed oil burner technicians install this nozzle as part of routine annual tune-ups or when combustion performance degrades.

This nozzle is suited for use in residential oil-fired furnaces, boilers, and water heaters that require a low-flow nozzle with a wide spray angle. The 0.65 GPH flow rate positions it in the low-capacity range, making it appropriate for smaller heating systems with lower BTU output requirements. The 80-degree angle is commonly specified by burner manufacturers for equipment designed to produce a broad, shallow flame envelope within the combustion chamber.

Key Features

• Type A hollow cone spray pattern for concentrated outer-edge fuel distribution
• 0.65 GPH flow rate suited for low-capacity oil-fired heating systems
• 80-degree spray angle for wide, shallow flame envelope
• Designed for use with No. 1 and No. 2 fuel oil in standard oil burner applications
• Drop-in replacement format compatible with standard oil burner nozzle adapters

Compatibility

Designed as an OEM-style replacement nozzle for residential and light commercial oil burner assemblies requiring a Type A hollow cone, 0.65 GPH, 80-degree nozzle specification.

Installation Notes

Oil burner nozzle replacement is performed by a licensed oil burner technician or qualified HVAC service professional. Always shut off power to the burner and close the fuel supply valve before removing the nozzle assembly. Use an appropriate nozzle wrench to avoid damage to the nozzle adapter, and handle the new nozzle carefully to prevent contamination of the orifice. Follow all applicable local codes and the burner manufacturer's service documentation when specifying nozzle ratings.
