-8AN Female to 1/2in Tub e Adapter Fitting

The -8AN Female to 1/2 inch Tube Adapter Fitting from Vibrant Performance is a precision hydraulic and fuel line connector engineered for high-performance automotive applications. It is ideal for custom fuel systems, coolant loops, and pressurized fluid lines on engine-swapped vehicles, turbo builds, and track cars. This adapter bridges the gap between AN-standard fittings and conventional tube sizes without compromising flow or integrity.

Constructed from billet aluminum, this fitting features precision-machined -8AN female ports and a 1/2 inch tube connection. It utilizes AN thread geometry, incorporating a 37-degree JIC flare seat to ensure metal-to-metal contact that withstands dynamic pressure cycling and thermal expansion. The stepped design minimizes turbulence at the transition point, which is critical for fuel atomization and system efficiency under boost or sustained load.

Vibrant Performance's quality standards ensure dimensional consistency across batches, eliminating the need to chase leak points after installation. The compact footprint and lightweight construction make it a practical choice for those fabricating fuel rails for LS swaps, upgrading cooling systems, or routing brake fluid in custom chassis. This fitting is designed for compatibility with a 1/2 inch OD hose, making it a reliable choice for serious automotive enthusiasts.
