Description

The Delavan 1.75 GPH 80° Type B Solid Cone Fuel Nozzle (identified by its blue protective cap) is a professional-grade heating and combustion component. It serves as a critical replacement part for the burner assemblies of hot water pressure washers, commercial boilers, and oil-fired furnaces, where it atomizes fuel to ensure highly efficient, clean, and stable combustion.

With a 1.75 GPH flow rate, this nozzle is engineered for medium-capacity heating coils, providing a balanced thermal output to heat water or air quickly and consistently.

Key Features

• Type B Solid Cone Pattern: Distributes atomized fuel droplets evenly throughout the entire spray cone. This uniform distribution ensures smooth ignition, stable flame geometry, and highly efficient heat transfer with minimal soot or carbon buildup.

• Premium Bi-Metal Construction: Features a heavy-duty brass body for rapid heat dissipation (which prevents fuel varnishing and residue buildup) combined with a precision-machined stainless steel internal metering section for maximum wear resistance.

• Integrated Sintered Filter: Equipped with a built-in mesh strainer at the base of the nozzle body to capture microscopic sediment, rust, and fuel contaminants before they can reach the orifice, preventing clogs and maintaining a consistent flame profile.

• Color-Coded Blue Cap: Standardized color coding by Delavan indicates a “Type B Solid Cone” nozzle configuration, allowing for quick and accurate identification during routine equipment servicing.
