AN To NPT 45 Degree -6 x 1/4in

The ALLSTAR PERFORMANCE AN to NPT 45 Degree -6 x 1/4in adapter (SKU ALL 49539) is a precision hydraulic and fluid line fitting designed to connect -6 AN (male) hose fittings to 1/4 inch NPT (National Pipe Thread) male ports. Constructed from aluminum and finished in black anodized coating, this adapter bridges two of the most common industrial and automotive fluid system standards with a 45-degree elbow configuration that facilitates space-efficient routing in tight engine bays, fuel systems, and hydraulic applications.

The 45-degree angle is critical for applications where straight-line plumbing is impractical or where vibration dampening benefits from directional offset. The -6 AN size accommodates high-flow requirements common in performance fuel systems, while the 1/4 inch NPT thread accommodates standard port sizes found on manifolds, blocks, and aftermarket equipment. Black anodized aluminum provides corrosion resistance and durability in engine compartments exposed to heat cycles, moisture, and fuel vapors. Each adapter is a single unit ready for installation without additional modifications.

This fitting is essential for builders integrating fuel systems with mixed fitting standards—common in custom fuel injection setups, carburetor conversions, bypass systems, and hydraulic brake retrofits where OEM ports use NPT threads but the hose assembly utilizes AN connections. The compact 2.3 x 1 x 4.1 inch footprint fits within typical engine bay constraints. Allstar Performance is recognized for precision fasteners and adapters used across racing, hot rodding, and high-performance automotive applications where fluid system reliability directly impacts engine performance and safety.
