The Fuelab expander port fitting steps a -10AN ORB port up to a -12AN 37° flare connection, providing a clean upsize transition for fuel plumbing. It enables attachment of -12AN flare lines to a -10AN ORB port via a direct ORB-to-37° AN adapter, useful when increasing line capacity without changing port placement or thread form.
