The Fragola -6AN tube nut in red is a single AN-style nut sized for -6AN tubing and fittings. It pairs with Fragola AN plumbing components to secure hard lines in fuel, oil, or other fluid runs where -6AN is specified. The color finish helps identify the line size and gives a finished look to custom AN lines without altering standard sealing or attachment behavior.
