Delavan 0.70-60-a Oil Burner Nozzle 0.70 Gph 60 Degree Hollow Cone

Product Description

The Delavan 0.70-60-A is a hollow cone oil burner nozzle rated at 0.70 gallons per hour with a 60-degree spray angle. It is designed for residential and light commercial oil-fired heating systems, including boilers and furnaces that require an open air spray pattern for clean, efficient combustion. HVAC technicians and heating service professionals rely on this type of nozzle to deliver precise fuel atomization, which is critical for proper ignition, stable flame shaping, and reduced smoke output. The hollow cone spray pattern distributes fuel along the outer edge of the cone, making it well suited for burners that need an open center flame. This pattern supports thorough air and fuel mixing, which helps minimize carbon buildup on the combustion chamber and heat exchanger surfaces. The 0.70-60-A features a brass housing and a stainless steel orifice. Brass resists corrosion from heating oil and holds up through repeated heat cycles. The stainless steel orifice maintains metering accuracy over long service intervals and resists clogging from fuel contaminants. The nozzle measures 1.625 inches in length and 0.75 inches in outer diameter. It uses 9/16-24 UNEF threads, which is the standard thread specification for most residential oil burner nozzle adapters. This ensures a secure, leak-free fit in compatible Delavan burner assemblies and many other standard oil burner heads. Replacing the oil burner nozzle annually is a standard practice in heating system maintenance. A worn or clogged nozzle causes poor atomization, rough ignition, excessive smoke, and higher fuel consumption. Installing the correct nozzle type and flow rate keeps the system operating within manufacturer specifications and helps pass annual efficiency and safety inspections.
