It is designed for residential and light-commercial oil-fired heating systems where the original nozzle has worn or requires seasonal replacement. Licensed oil burner technicians and heating contractors install this nozzle as part of routine annual tune-ups or emergency service calls. Matching GPH rating, spray angle, and cone type to the original specification is critical for proper combustion efficiency and equipment safety.\u003c\/p\u003e\u003cp\u003eThis nozzle fits standard oil burner assemblies found in forced-air furnaces, boilers, and water heaters that fire on No. 2 fuel oil. It is sized for systems requiring a 1.0 GPH firing rate at a typical supply pressure of 100 psi. The 80-degree spray angle and Type A cone pattern suit a range of combustion chamber geometries commonly found in residential heating equipment. Always confirm the GPH, spray angle, and cone type stamped on the original nozzle before installing a replacement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.0 GPH flow rate for precise fuel delivery at standard operating pressure\u003c\/li\u003e\n\u003cli\u003e80-degree spray angle compatible with a wide range of combustion chamber depths\u003c\/li\u003e\n\u003cli\u003eType A hollow cone pattern for even fuel atomization\u003c\/li\u003e\n\u003cli\u003eOEM-grade replacement manufactured in the USA\u003c\/li\u003e\n\u003cli\u003eGenuine DELAVAN product for consistent combustion performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement nozzle for oil-fired furnaces, boilers, and water heaters requiring a 1.0 GPH, 80-degree, Type A nozzle.
