6AN Male to 3/8in Tube Adapter Fitting Black

The FRAGOLA 6AN Male to 3/8in Tube Adapter Fitting in Black is a straight-through hose adapter engineered for high-pressure fuel, oil, and coolant line applications. Constructed from aluminum and finished in black anodized coating, this adapter bridges 6 AN (male) ports to 3/8-inch tubing, providing a compact, reliable connection point in engine bay plumbing systems, fuel rail setups, and custom hydraulic builds where space and secure fitting integrity are critical.

The aluminum construction delivers lightweight performance without sacrificing structural integrity under pressure. Black anodizing provides corrosion resistance and thermal stability—a significant advantage in engine compartment environments where temperature cycling and moisture exposure occur. The straight configuration eliminates unnecessary flow path complexity, maintaining consistent pressure transfer and reducing turbulence. The 6 AN male connection accepts standard AN-spec hose and fittings, while the 3/8-inch tube end accommodates hardline or flexible tubing with appropriate crimped fittings or adapters, making this piece a versatile intermediate component in custom plumbing layouts.

This adapter is essential for builders working with mixed fitting standards, retrofit fuel system upgrades, and racing applications where AN plumbing delivers superior pressure ratings and reliability compared to metric or JIC alternatives. Weighing just 0.04 lbs and measuring 4.15 inches in length, it integrates seamlessly into confined engine bays and tight manifold arrays. Whether assembling a forced-induction fuel system, custom cooling loop, or turbo oil supply circuit, this FRAGOLA adapter ensures code-compliant transitions between different hose and tube standards without sacrificing flow capacity or structural confidence.
