Delavan 1.65-70-a Oil Burner Nozzle 1.65 Gph 70 Degree Hollow Cone

Product Description

The Delavan 1.65-70-A is a residential oil burner nozzle designed for use in oil-fired heating systems. It delivers a flow rate of 1.65 GPH at a rated pressure of 100 PSI. The spray angle is 70 degrees, and the spray pattern is Type A, which means a hollow cone. This combination is one of the most common setups used in residential oil burners across North America. HVAC technicians and heating contractors rely on this nozzle during annual tune-ups, burner replacements, and efficiency upgrades. Choosing the correct nozzle type, angle, and flow rate is critical to clean combustion. A hollow cone pattern atomizes fuel oil and distributes it evenly in a ring-shaped spray. This promotes thorough mixing with combustion air, which helps reduce soot buildup, lowers smoke output, and improves overall burner efficiency. The 70-degree angle is well suited for shorter combustion chambers found in many residential furnaces and boilers. The nozzle body is constructed from brass, which resists corrosion and holds up well in fuel oil environments. The orifice disc is made from steel for precision atomization and long service life. A sintered filter is integrated into the nozzle to catch fine particulates before they can clog the orifice. This helps maintain consistent spray quality over time. The nozzle meets ISO 9001 manufacturing standards, which ensures consistent dimensional accuracy and performance from unit to unit. This is especially important when replacing a nozzle mid-season on a running system. The Delavan 1.65-70-A is a direct replacement for heating systems that call for a 1.65 GPH, 70-degree, Type A hollow cone nozzle. It is compatible with standard threaded nozzle adapters and fits most residential oil burner assemblies. Keep spares on hand for fast service calls.
