The Fragola 6AN tube nut is a single replacement nut for AN‑style tubing connections commonly used in engine and fluid systems. Offered individually, it secures fittings on -6AN lines where a dedicated nut is needed for hose or tube assemblies. Keep spares for maintenance or custom plumbing to preserve reliable, leak‑free connections in fuel, oil, or coolant circuits.
