The Fuelab expander port fitting converts a -6AN ORB port to a -8AN 37° flare connection, giving a straightforward up-size option for fuel plumbing. It provides a direct ORB-to-37° AN expander so larger -8AN flare lines can be used with a -6AN ORB port, useful when upsizing fuel delivery lines while maintaining sealing form.
