Delavan 0.50-70-a Oil Burner Nozzle 0.50 Gph 70 Degree Hollow Cone Type a

Product Description

The Delavan 0.50-70-a is a precision-engineered oil burner nozzle designed for residential and light commercial heating applications. This nozzle delivers a flow rate of 0.50 gallons per hour at a 70-degree spray angle using a Type A hollow cone pattern. It is manufactured in the USA from solid brass, ensuring durability and resistance to the demands of oil-fired heating systems. HVAC technicians rely on Delavan oil nozzles as a trusted standard in the industry for consistent, reliable performance across a wide range of oil burner equipment including Beckett, Carlin, Riello, and Weil-McLain burner systems. The hollow cone spray pattern produced by this nozzle creates a ring-shaped distribution of atomized fuel oil, which is well suited for smaller firing rates and certain burner head configurations. Delavan uses an advanced machining process to produce precise spray angles and improved spray uniformity, which supports efficient combustion and cleaner burns. The redesigned distributor features shorter tangential slots to reduce the risk of plugging, a common field concern with oil nozzles that encounter dirty fuel. The aerodynamic body configuration allows for optimized fuel flow and consistent atomization shot to shot. Proper nozzle selection is critical to achieving the correct fuel-to-air ratio, minimizing soot buildup, and keeping heat exchangers clean. Replacing oil burner nozzles annually during routine tune-ups is standard practice for HVAC service professionals. The 0.50-70-a is a direct replacement nozzle stocked by heating distributors across North America and is ISO certified for quality assurance. At 0.50 pounds and compact packaging dimensions, this nozzle ships easily and stores well in a service van parts inventory.
