Radium Engineering designed the 6AN ORB to 6AN Male Fittings FST Orifice as a purpose-built solution that connects 6AN ORB to 6AN Male Fittings FST Orifice, giving the system a direct transition between the two connection standards. That keeps the plumbing compact and serviceable while avoiding a stack of extra adapters in a fuel, oil, or other compatible fluid system.

Key sizing for this version includes 6AN ORB and 6AN AN/ORB sizing, so it should be matched to the rest of the system before installation. Match both connection standards exactly and use the correct sealing method for the thread type being installed.
