Male Adapter Fitting #6 x 5/8-20 Carter Black

The Male Adapter Fitting #6 x 5/8-20 Carter Black by FRAGOLA is a precision straight-thread adapter designed for custom fuel system builds, hydraulic lines, and high-pressure fluid transfer applications. This fitting bridges two different port standards—a 6 AN (AN6) male connection on one end and a 5/8-20 male port on the other—making it essential for retrofitting aftermarket fuel rails, carburetors, pressure regulators, and remote filter mounts onto vehicles with mixed legacy and modern plumbing.

Machined from aluminum and finished in black anodizing, the Male Adapter Fitting #6 x 5/8-20 Carter Black provides lightweight corrosion resistance and a clean, professional appearance under the hood. The straight-thread design allows for direct, inline connections in tight engine bays or fuel cell compartments, eliminating the need for multiple fittings or custom fabrication. Black anodized aluminum offers superior oxidation protection compared to bare aluminum, ensuring long-term durability against fuel, oil, coolant, and weather exposure.

Mechanics, fabricators, and serious enthusiasts working on fuel-injected vehicles will find this adapter invaluable for upgrading classic hot rods or adapting specialty components in high-performance builds. Its compatibility with a vast range of aftermarket and OEM components makes it a versatile choice for various applications. Whether you're enhancing fuel delivery or integrating new components, this fitting simplifies the process and enhances performance.
