AN To NPT 90 Degree -6 x 1/4in

The AN to NPT 90 Degree -6 x 1/4in adapter from ALLSTAR PERFORMANCE (ALL 49569) is a precision fluid-line fitting designed to bridge male AN (Army-Navy) ports to male NPT (National Pipe Thread) ports at a 90-degree angle. This adapter is essential for high-performance automotive systems—including fuel injection, cooling, and hydraulic circuits—where different threading standards must connect reliably. Engineers and technicians rely on these adapters to maintain system integrity while accommodating space constraints or existing component layouts that require directional flow changes.

Manufactured from aluminum and finished in durable black anodize, this adapter combines lightweight construction with corrosion resistance and thermal stability. The -6 AN male port accepts standard -6 hose and fitting assemblies, while the 1/4 inch NPT male thread accommodates pipe adapters and manifold ports commonly found in industrial and automotive applications. The 90-degree geometry eliminates the need for separate elbows and secondary fittings, reducing connection points and potential leak paths while simplifying plumbing layouts in confined engine bays or chassis areas where straight runs are impractical.

This fitting performs best in systems operating within moderate pressure ranges typical of custom fuel systems, coolant loops, and power steering circuits. Installation requires hand-tightening with appropriate wrenches to both the AN and NPT ports, ensuring proper sealing without over-torque. Buyers should verify that the -6 AN hose size and 1/4 inch NPT thread match their existing or planned component specifications before installation. The compact 2.3 × 0.95 × 4.05 inch profile fits tight spaces where standard straight adapters would interfere with engine components or frame members.
