Reducer Bushing Fitting -8an to Male -6 ORB

The Waterman Racing Comp. Reducer Bushing Fitting -8AN to Male -6 ORB is a precision aluminum adapter designed to bridge two different AN (Air & Nitrogen) port sizes in high-flow fluid systems. This straight-port fitting transitions from -8 AN male connections to -6 ORB (O-Ring Boss) female ports, making it essential for custom fuel, oil, and coolant line configurations where port diameter mismatches occur. The black anodized aluminum construction resists corrosion while maintaining lightweight performance characteristics critical in racing and motorsport applications.

AN fittings operate on a standardized sizing convention where the dash number corresponds to the tube outer diameter in sixteenths of an inch. The -8 to -6 reduction accommodates systems where larger-diameter inlet or feed lines must connect to smaller-diameter component ports. The O-Ring Boss design on the female end eliminates the need for separate ferrules, instead relying on a precision-machined port and complementary O-ring seal for vibration-resistant, leak-proof connections. This geometry is preferred in racing fuel systems and custom hydraulic builds where reliability under sustained load and temperature cycling is non-negotiable.

Applications span professional engine building, fuel system tuning, oil circuit modifications, and custom cooling loops where OEM port configurations don't match aftermarket component specifications. The compact 0.04 lb weight reflects the minimal material footprint, and the straight-port configuration maintains optimal flow characteristics without elbows or directional restrictions. This adapter is particularly valuable when integrating performance fuel regulators, remote oil filters, or custom gauge manifolds into existing -8 AN line runs, eliminating the need for expensive custom hose routing or port modifications.
