Female -12AN to Male -16AN Adapter Fitting

The Female -12AN to Male -16AN Adapter Fitting by Vibrant Performance is an essential hydraulic line connector for custom fuel systems, turbo installations, and high-flow cooling circuits where port sizes don't match between components. This adapter effectively addresses common sizing mismatches encountered when integrating aftermarket fuel rails, surge tanks, or transmission coolers into existing engine bays.

Constructed from aluminum alloy, the Female -12AN to Male -16AN Adapter Fitting features sealed threads and a dual-thread design that accommodates stepped port configurations without leakage under pressure. The -12 AN female inlet receives existing -12 AN hose assemblies while the -16 AN male outlet threads directly into larger-capacity component ports, maintaining full flow integrity across the size transition.

This fitting is ideal for those upgrading from OEM -12AN lines to larger -16AN capacity systems or consolidating mixed-size plumbing on street rods or race vehicles. Vibrant Performance's extrusion and threading standards ensure consistent fit and minimal turbulence through the adapter body, which is critical for fuel delivery systems where cavitation or pressure loss can compromise performance.
