-6m To -4m Flare Rdcr

The XRP-XTREME RACING PROD. -6m To -4m Flare Reducer (SKU XRP991906) is a precision aluminum adapter fitting engineered for high-performance fuel and fluid systems where line size transitions are critical. This straight-through 6 AN male to 4 AN male reducer maintains flow integrity while enabling compatible connections between larger and smaller diameter hoses—essential in racing, marine, and performance automotive applications where pressure rating and leak-free operation directly impact system reliability.

Constructed from aluminum with blue anodized finish, this fitting delivers corrosion resistance and durability in demanding environments. The flare reducer design accommodates standard AN flare connections, commonly used in high-performance fuel delivery, cooling, and hydraulic systems where vibration resistance and secure sealing are non-negotiable. Weighing just 0.05 lbs and measuring 2.7 x 1.2 x 3.6 inches, the compact form factor integrates into tight engine bays and compartments without sacrificing structural integrity or connection security. The straight-through geometry minimizes turbulence and pressure drop across the transition.

This adapter serves marine engine builders, racing teams, and performance enthusiasts who demand precision component compatibility. Whether you're upgrading fuel system routing, reconfiguring cooling lines, or adapting OEM assemblies to aftermarket components, a properly sized flare reducer eliminates the need for improvised adapters or oversized fittings that compromise flow characteristics. The blue anodized finish provides both visual identification and environmental protection, particularly valuable in saltwater marine applications where bare aluminum degradation is a constant concern.
