Riello 3006974 Oil Burner Nozzle Tube 10 Inches 40 Series F5

Product Description

The Riello 3006974 is a long nozzle oil tube designed for use with the Riello 40 Series F5 oil burner. This replacement part delivers fuel oil from the supply line to the nozzle tip, where it is atomized and mixed with air before combustion. Proper fuel delivery is critical in oil-fired heating systems, and a well-fitted nozzle tube ensures consistent spray patterns, clean ignition, and efficient combustion. The 3006974 measures 10 inches in length, making it a direct-fit replacement for the F5 burner platform without modification. HVAC technicians and oil burner service professionals rely on OEM-spec components like this to maintain tight tolerances and meet manufacturer service requirements. The Riello 40 Series is a widely installed line of residential oil burners used across North America, and the F5 model is a common unit found in homes with forced hot water or hot air systems. When servicing these units, replacing a worn or damaged nozzle tube is a standard part of a seasonal tune-up or repair call. Using the correct length and specification tube prevents fuel leakage, misalignment at the nozzle holder, and combustion inefficiency. This tube carries CSA B139 approval, meeting the Canadian Standards Association requirements for oil-burning equipment installation. This approval is relevant for service work in both Canadian and U.S. markets where code compliance is required. The application is residential, making it the right choice for home heating service calls. HVAC technicians, oil burner installers, and plumbing and heating contractors working on Riello equipment should keep this part on hand for fast turnaround on F5 burner service.
