-8AN Female to 1/4inNPT Male Swivel Fitting

The -8AN Female to 1/4 inch NPT Male Swivel Fitting is a precision hydraulic and pneumatic adapter designed for systems requiring reliable thread-to-port conversion in high-performance applications. Built by VIBRANT PERFORMANCE, this fitting seamlessly bridges AN (Army-Navy) female connections to standard NPT (National Pipe Thread) male ports, making it essential for custom fuel systems, coolant lines, oil coolers, and pressurized fluid circuits where port compatibility varies across components. The swivel design accommodates hose movement without rotational stress on connected fittings, reducing installation complexity and enhancing durability in vibration-prone environments.

Constructed from aluminum and finished in black anodize, this fitting delivers corrosion resistance and a clean aesthetic finish while maintaining lightweight properties critical in motorsports and aerospace applications. The -8AN (1/2 inch outer diameter) female port accepts standard -8 hoses and fittings, while the 1/4 inch NPT male thread matches common industrial and aftermarket manifold outlets without modification. Black anodizing protects against oxidation and chemical exposure, extending service life in engine bays, transmission coolers, and fuel management systems where temperature and pressure cycling occur regularly.

This adapter is indispensable for custom-built hot rods, marine engines, racing platforms, and industrial fluid systems where OEM ports require conversion to AN standards. Installation is straightforward—thread the NPT male end into the receiving port using appropriate thread sealant, then attach -8 hose or fitting to the swivel female end. The compact footprint (3.54 x 1 x 6.3 inches) fits tight engine compartments, while the swivel joint allows hose routing flexibility without strain. Verify NPT thread size compatibility with your manifold or component before purchase to ensure proper fit and pressure integrity.
