Delavan 3.00-70-b 3.00 Gph 70 Degree Solid Cone Type B Oil Burner Nozzle

Product Description

The Delavan 3.00-70-B is a solid cone Type B oil burner nozzle designed for residential heating applications. It delivers a flow rate of 3.00 gallons per hour at a standard operating pressure of 100 PSI. The 70-degree spray angle gives technicians reliable coverage in a wide range of burner configurations. This nozzle is a go-to choice for HVAC professionals servicing oil-fired furnaces, boilers, and water heaters where consistent atomization matters most.

The Type B solid cone spray pattern distributes fuel droplets evenly throughout the entire spray cone. This uniform distribution supports smooth ignition and efficient combustion, which reduces the risk of delayed ignition, after-drip, and carbon buildup. At flow rates above 8.00 gallons per hour, the pattern becomes progressively more hollow, but at 3.00 GPH this nozzle maintains a full, stable cone that keeps combustion clean and controlled.

The body is constructed from brass, offering strong corrosion resistance in the presence of heating oil and common fuel additives. The orifice disc is made from steel for precise, repeatable flow performance over time. A Monel strainer filters incoming fuel before it reaches the orifice, protecting against particulate contamination that could clog or erode the nozzle tip. Monel is a nickel-copper alloy known for exceptional resistance to fuel degradation and corrosion, making it a durable choice for long-term field performance.

This nozzle meets ISO 9001 quality standards, so technicians can count on consistent manufacturing tolerances from unit to unit. Whether replacing a worn nozzle during a seasonal tune-up or upgrading combustion performance on a residential oil burner, the Delavan 3.00-70-B fits standard nozzle ports and threads found across most major burner brands.

• Solid cone Type B spray pattern for uniform droplet distribution and stable combustion
• Brass body and steel orifice disc for durability and precise flow control
• Monel strainer filters fuel to protect the orifice and extend service life

Product Highlights

The Delavan 3.00-70-B delivers a consistent 3.00 GPH flow rate at a 70-degree spray angle, making it a reliable replacement nozzle for residential oil burners that demand clean ignition and efficient fuel atomization.
