Aluminum Fitting -6AN x -10AN (7/8-14) O-ring

The Aluminum Fitting -6AN x -10AN (7/8-14) O-ring is a precision-engineered adapter designed to facilitate seamless transitions within high-performance automotive fluid systems. This component is essential for technicians and enthusiasts who need to bridge the gap between different plumbing sizes in oil cooling, fuel delivery, or transmission cooling circuits. By providing a direct connection between -10 AN O-ring ports and standard -6 AN lines, this fitting eliminates the need for complex, multi-piece configurations that can increase the risk of failure points.

Constructed from high-grade aluminum, this straight adapter features a natural finish that provides excellent resistance to corrosion and environmental wear. The technical design includes a -10 AN male side with 7/8-14 threads and a dedicated O-ring seal, ensuring a positive, leak-proof interface against flat-faced components. The opposite end features a standard -6 AN male flare, which maintains high flow rates while securing braided or rubber hoses with industry-standard reliability. The lightweight nature of the aluminum construction makes it an ideal choice for racing applications where reducing every ounce of vehicle weight is a priority.

Custom builders benefit significantly from this adapter when integrating aftermarket coolers or remote filter mounts into modern engine bays. It is specifically designed for compatibility with any component utilizing a 7/8-14 threaded port, offering a simplified installation process for those following detailed specifications for their fluid management systems. Whether you are performing a routine upgrade or a complete system overhaul, this fitting ensures your plumbing remains secure under the high pressures typical of performance driving. Review your system requirements to ensure this dual-male adapter meets your specific plumbing layout needs before you buy.
