The Fragola -4AN tube nut in red is a single AN-style tube fitting nut for use with -4AN tube lines. It complements Fragola AN plumbing by securing tubing to AN fittings in fuel, oil, or coolant lines where -4AN sizing is specified. The simple, color-coded nut helps identify line size and provides a tidy finish for custom hard-line runs without altering standard AN functionality.
