Delavan 0.85-80-ss 0.85 Gph 80 Degree Semi-solid Oil Burner Nozzle

Product Description

The Delavan 0.85-80-ss is a semi-solid spray oil burner nozzle designed for residential heating systems. It delivers a flow rate of 0.85 gallons per hour at a rated pressure of 100 PSI. The 80-degree spray angle produces a semi-solid (SS) pattern, which concentrates fuel toward the center of the flame while still providing good coverage across the combustion chamber. This spray pattern is commonly used in older burner designs and applications where a denser flame core is needed for reliable ignition and combustion efficiency.

The nozzle body is constructed from brass, which resists corrosion and holds up well in the high-temperature environment of an oil burner. The orifice disc is made from steel for durability and precise fuel atomization. A sintered filter screens out debris before it reaches the orifice, helping protect the spray pattern and extend nozzle life. The design meets ISO 9001 manufacturing standards, ensuring consistent dimensional accuracy and spray performance from unit to unit.

HVAC technicians and oil burner service professionals rely on the Delavan 0.85-80-ss as a direct replacement nozzle for annual maintenance and service calls. Replacing the nozzle at each tune-up is standard practice for keeping oil-fired boilers and furnaces running at peak efficiency. Using the correct flow rate and spray angle is critical to proper burner setup, combustion air balance, and minimizing soot and smoke. This nozzle fits standard 0.75-inch by 16-thread nozzle adapters used across most residential oil burner brands including Beckett, Riello, Carlin, and Wayne.
