The Straight Adapter Fitting #6 x 1/2 MPT Black by FRAGOLA is a precision hydraulic and fuel system connector designed to join AN (Army-Navy) hose lines to NPT (National Pipe Thread) ports with reliable, leak-free performance. This fitting serves as a critical bridge component in high-pressure fluid transfer applications, making it essential for automotive enthusiasts, race teams, and hydraulic system builders who demand compatibility between metric-style hose ends and standard pipe thread ports. The straight configuration eliminates bends at the connection point, reducing turbulence and pressure drop while simplifying installation in confined engine bays or tight equipment layouts.
Constructed from aluminum and finished in black anodized coating, this adapter fitting delivers corrosion resistance and lightweight durability critical for motorsport and marine environments. The #6 AN male inlet connects to 1/2-inch NPT male outlets, providing a secure threaded interface that withstands vibration and thermal cycling without loosening. Black anodized aluminum construction offers superior protection against oxidation while maintaining the low weight advantage essential in performance applications, and the precision-machined threads ensure proper sealing without over-torquing. The compact footprint—measuring 1.75 by 1.05 by 4 inches and weighing only 0.05 pounds—makes this fitting ideal for space-constrained installations where weight savings directly impact vehicle dynamics.
Professional installers and custom builders rely on FRAGOLA adapters for fuel injection systems, transmission coolers, power steering conversions, and turbo feed lines where AN hose compatibility with NPT port infrastructure is mandatory. The straight design works particularly well in fuel system retrofits and auxiliary cooler installations where flow efficiency and minimal pressure loss directly affect engine performance and component longevity. Proper installation requires use of appropriate thread sealant on the NPT male end and correct torque specifications to avoid thread stripping; this fitting pairs seamlessly with standard #6 AN hoses and fittings across racing, restoration, and custom fabrication projects.
