This nozzle delivers precise fuel atomization at a rated flow of 0.579 gallons per hour, making it a direct fit for the reduced fuel demands of mobile home oil-fired furnaces and boilers. HVAC technicians and heating contractors working on manufactured housing rely on this type of nozzle to maintain clean, efficient combustion at low firing rates. The MH designation stands for Mobile Home, and this design addresses one of the most common service challenges in low-flow oil burner applications: nozzle plugging. Standard residential nozzles can clog more easily when operating at very low flow rates, leading to hard starts, poor combustion efficiency, and frequent service calls. The 579-mh minimizes this plugging risk through its purpose-built orifice disc design. The body is constructed from brass, a material widely used in oil burner nozzles for its resistance to corrosion and compatibility with No. 2 fuel oil. The steel orifice disc provides dimensional stability and consistent spray pattern performance over time. This nozzle is rated for operation at 100 PSI pump pressure, which is the standard operating pressure for most residential oil burner pumps. The temperature rating of 80 degrees Fahrenheit aligns with typical indoor mechanical room conditions. Manufactured to ISO 9001 quality standards, the 579-mh offers the dimensional consistency and spray quality that heating technicians need for reliable performance. It is a direct replacement nozzle suitable for annual tune-up and maintenance work on mobile home oil heating equipment.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMH-type low-capacity nozzle designed to prevent plugging at low fuel flow rates\u003c\/li\u003e\n\u003cli\u003eBrass body construction with steel orifice disc for durability and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eRated at 100 PSI operating pressure to match standard residential oil burner pump output\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Delavan 579-mh delivers consistent, clog-resistant atomization at 0.579 GPH for mobile home oil burner systems.
