The Fragola swivel expander adapts an -10AN nut to a -12AN male flare, providing a reliable threaded transition between these AN sizes. Its swivel function helps align fittings during assembly, useful when connecting mismatched hose ends or adapters in fluid systems. Use this expander where an AN size change is necessary and verify thread and flare compatibility before final connection.
