Female -8AN to Male -12AN Adapter Fitting

The Female -8AN to Male -12AN Adapter Fitting by Vibrant Performance (MPN 10868) is an essential component for custom fuel, coolant, and brake line systems where mismatched port sizes must be bridged with precision. Whether you're upgrading a fuel injection system, installing a custom radiator setup, or fabricating a high-performance cooling loop, this adapter allows you to connect -8AN female outlets to -12AN male ports without compromising flow integrity or safety. Built for serious automotive work, this fitting eliminates the need for custom hose assemblies and reduces potential leak points in critical engine systems.

Constructed from aerospace-grade aluminum, the Female -8AN to Male -12AN adapter maintains the reliability Vibrant Performance is known for across professional tuning and OEM replacement markets. The -8AN inlet (female) accommodates standard braided hose fittings, while the -12AN outlet (male) threads directly into OEM or aftermarket component ports. Precision machining ensures zero leakage under pressure; the compact 3.54-inch length and lightweight 0.09-pound design integrate cleanly into engine bays without interfering with belts, pulleys, or hoses. Anodized finish resists corrosion and maintains aesthetic consistency with other performance plumbing components.

This adapter is ideal for LS engine swaps, fuel system upgrades, supercharger installations, and custom cooling configurations where OEM ports do not match aftermarket hose sizes. Professional mechanics and dedicated enthusiasts benefit from the reduced labor time—no custom bends or welding required. Compatible with any system using AN-style fittings, it works with fuel rails, water crossovers, turbo feed lines, and intercooler piping. Always verify port threads and system pressure ratings before installation to ensure proper seating and safety under operating conditions.
