The Toyotomi Flare Nut (3/8" Fuel Line), part number PHAN-FLARENUT, is a replacement fuel system fastener designed for 3/8" flare-style fuel line connections on select Toyotomi and Toyostove heaters. It provides a mechanical sealing connection between fuel line components and threaded fittings to ensure a secure, leak-resistant joint when routing fuel from the supply to the burner assembly. This flare nut meets original equipment specifications and is intended for use where the existing flare nut is worn, damaged, or no longer provides a reliable seal.
This flare nut is typically used in the fuel line system where a 3/8" flare connection is required, such as between supply tubing, fuel shutoff valves, or pipe fittings on compatible heaters. Proper installation involves ensuring the mating surfaces are clean and aligned so the flare nut can compress the tubing flare against the threaded fitting and form a consistent seal. Service manuals and parts diagrams should be consulted to verify correct placement and torque values during installation to maintain safe and reliable fuel delivery.
