6AN to 8AN O-Ring Port Adapter Black Male Male

The REDHORSE PERFORMANCE 6AN to 8AN O-Ring Port Adapter Black Male Male (part number 920-06-08-2) is a precision hydraulic and fuel line fitting designed for systems requiring a straight adapter between 6 AN male and 8 AN male O-ring ports. This aluminum adapter with black anodized finish serves as a critical component in high-performance fuel systems, cooling circuits, and hydraulic applications where reliable port-to-port connections are essential.

The 920 Series straight adapter design provides a direct connection without directional restrictions, making it ideal for plumbing configurations where space is limited or where multiple fitting angles would create clearance conflicts. The O-ring port design ensures a sealed connection that resists pressure loss and fluid weeping under operational stress. The black anodized aluminum construction balances weight savings with durability while offering corrosion resistance in both engine bay and marine environments. At 0.07 lbs, the compact footprint (2.75 × 1.05 × 3.8 inches) fits seamlessly into tight engine compartments and aftermarket fuel rail systems.

This adapter is essential for builders and technicians upgrading fuel delivery systems, cooling loops, or hydraulic circuits where port sizes or configurations don't align with direct hose connections. It's commonly used in custom fuel system builds, high-flow cooling system modifications, and performance engine conversions where AN fittings provide superior reliability over barbed or compression alternatives. The 6AN-to-8AN step-down is particularly useful when connecting smaller feed lines to larger distribution blocks or when integrating components from different OEM or aftermarket suppliers.
