AN To NPT Straight -6 x 1/2in

The ALLSTAR PERFORMANCE AN to NPT Straight -6 x 1/2in adapter (SKU ALL 49511) is a precision hydraulic and pneumatic fitting designed to connect AN-spec male ports to 1/2-inch NPT male threads. This aluminum adapter bridges two industry-standard connection systems, making it essential for custom fluid and air line systems where port compatibility would otherwise require component modification.

Constructed from aluminum and finished in black anodize, the fitting combines lightweight construction with corrosion resistance—a critical advantage in applications exposed to moisture or salt air. The straight-body design eliminates unnecessary bends, reducing turbulence in fluid transfer systems and simplifying installation in tight mounting spaces. The -6 AN male port accommodates standard -6 AN hose and tubing commonly used in fuel systems, oil coolers, transmission lines, and pressurized brake systems, while the 1/2-inch NPT male end threads directly into factory or aftermarket tank bungs, manifolds, and component ports without adapters.

This adapter is ideal for hot rod builders, racing teams, and system integrators who need reliable cross-standard connections without permanent component modification. It's commonly used in custom engine bay layouts, fuel system upgrades, oil circulation systems, and pneumatic tool installations where existing NPT-threaded components must integrate with AN-spec hose routing.

ALLSTAR PERFORMANCE has built a reputation in the performance automotive and industrial sectors for precision fittings and adapters that meet tight tolerances and real-world durability demands. This straight AN-to-NPT adapter is designed as a single-unit solution, eliminating the need for multi-stage adapter stacks that increase weight and failure points.
