Delavan 0.75-80-ss 0.75 Gph 80 Degree Semi-solid Oil Burner Nozzle

Product Description

The Delavan 0.75-80-ss is a semi-solid (SS) oil burner nozzle designed for residential heating applications. It delivers a flow rate of 0.75 gallons per hour at a standard operating pressure of 100 PSI and produces an 80-degree spray angle. HVAC technicians and oil burner service professionals rely on this nozzle type for precise fuel atomization in forced-air furnaces, boilers, and water heaters that burn No. 2 fuel oil.

Delavan oil burner nozzles are manufactured to ISO 9001 quality standards, which means every unit meets consistent dimensional and performance tolerances. The body is constructed from brass, a material chosen for its corrosion resistance and machinability. The orifice disc is made from steel, which holds its shape under repeated thermal cycling and high-pressure fuel flow. A sintered filter is integrated into the nozzle assembly. This filter traps fine particles before they reach the orifice, protecting the spray pattern from contamination and extending service life.

The semi-solid spray pattern falls between a solid-cone and hollow-cone pattern. It concentrates fuel toward the center of the spray cone while maintaining coverage across the full angle. This makes it well suited for residential oil burners that require stable ignition and efficient combustion across a range of firing conditions. The 80-degree angle is a common specification for residential burner heads and matches the geometry of many standard retention-head and conventional burner configurations.

When servicing an oil heating system, nozzle replacement is a standard annual maintenance step. Replacing the nozzle each heating season ensures proper atomization, reduces smoke and soot buildup, and maintains fuel efficiency. The Delavan 0.75-80-ss is a direct replacement option for burners requiring a 0.75 GPH, 80-degree, semi-solid nozzle.

• Flow rate of 0.75 GPH at 100 PSI operating pressure
• 80-degree semi-solid spray pattern for stable residential oil burner combustion
• Brass body with steel orifice disc and integrated sintered filter
