Description

The 1.75 GPH 60° Type A Hollow Cone Fuel Nozzle (typically identified by a red protective cap) is a professional-grade heating and combustion component. It serves as a vital replacement part for the burner assemblies of hot water pressure washers, commercial boilers, and oil furnaces, where it atomizes fuel to ensure highly efficient, clean, and stable heat generation.

With a 1.75 GPH flow rate and a narrower 60° spray angle, this nozzle provides a precise, medium-capacity thermal output engineered specifically for long, narrow combustion chambers that utilize a hollow cone flame profile.

Key Features

• Type A Hollow Cone Pattern: Distributes atomized fuel droplets primarily around the outside of the spray cone, leaving a hollow center. This configuration matches specific burner air patterns, offering smooth ignition, excellent flame stability, and reduced smoke or soot production.

• Narrow 60° Spray Angle: Provides a longer, more concentrated flame profile compared to wider angles (like 80° or 90°). This prevents the flame from touching the sides of narrow heating coils or deep combustion chambers, protecting the equipment from heat damage.

• Premium Bi-Metal Construction: Features a heavy-duty brass body for rapid heat dissipation (preventing 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 impurities before they can reach the orifice, maintaining a consistent flame profile.

• Color-Coded Red Cap: Standardized color coding indicates a “Type A Hollow Cone” nozzle configuration, allowing technicians to quickly identify the correct pattern type during routine maintenance.
