Hose Fitting #6 Straight Pro-Flow

The FRAGOLA Hose Fitting #6 Straight Pro-Flow is a professional-grade hydraulic hose end designed for high-pressure fluid transfer applications in performance engines, race systems, and industrial hydraulic setups. This straight hose fitting accommodates 6 AN hose to 6 AN female connections, making it compatible with both custom and OEM performance cooling, fuel, and hydraulic lines where reliable, leak-free connections are non-negotiable.

Constructed from aluminum and finished in distinctive blue and red anodized coating, this 2000 Series Pro-Flow fitting combines low-restriction flow characteristics with corrosion resistance. The straight configuration eliminates unnecessary bends, reducing turbulence and pressure loss—critical factors in high-RPM engine bays where every PSI counts. The compact 1.45 × 1.2 × 4.15-inch profile fits tight engine compartments typical of race cars, marine vessels, and custom builds without compromising accessibility or serviceability.

This fitting serves engine builders, fabricators, and technicians who demand precision hydraulic connections for cooling systems, fuel injection systems, power steering circuits, and transmission cooler lines. Whether you're assembling a naturally aspirated high-horsepower engine, a forced-induction system, or a closed-loop cooling circuit for extreme performance, the Pro-Flow design minimizes bottlenecking and ensures consistent pressure delivery under sustained operation.

FRAGOLA Pro-Flow fittings are engineered to SAE specifications and widely used in sanctioned motorsports, marine, and aftermarket sectors where reliability under pressure is verified through real-world track and dyno testing. The 6 AN size is standard in modern performance applications, ensuring interchangeability with industry-standard hose, adapters, and manifolds.
