The Fuelab reducer port fitting adapts a -10AN ORB port to a -8AN 37° flare connection, allowing a reliable down-size transition in fuel lines. It gives a direct ORB-to-37° AN reducer option for installations that need a smaller flare line tied into a -10AN ORB port while keeping sealing geometry intact.
