Female Straight Union Ad apter -12AN

The Female Straight Union Adapter -12AN from Vibrant Performance is a precision hydraulic fitting designed to connect two female -12AN ports in a direct, inline configuration. This adapter serves as an essential component in high-pressure fluid systems, including fuel, oil, and coolant lines found in performance vehicles, race cars, and custom engine builds. The straight union design eliminates unnecessary bends and reduces fluid turbulence, making it ideal for builders who require a compact, reliable connection point between two matching female fittings.

Manufactured from aerospace-grade aluminum, this fitting is finished in black anodized coating to resist corrosion and maintain structural integrity under sustained pressure and temperature cycling. The -12AN designation refers to the SAE JIC flange thread standard, providing a secure, leak-free seal when properly installed with appropriate hose or tubing. The adapter's straight geometry allows for direct female-to-female union without angle restrictions, simplifying installation in confined engine compartments and custom plumbing layouts common in motorsports applications.

This fitting is essential for custom fuel system builders, bracket-mounted reservoir setups, and modular cooling or lubrication lines where off-the-shelf hose lengths don't fit. The lightweight aluminum construction (0.15 lbs) makes it suitable for weight-conscious racing builds without sacrificing durability. Compatibility extends across any system using standard -12AN female ports, including aftermarket fuel rails, oil coolers, transmission coolers, and catch-can systems. Proper installation requires appropriate thread sealant or PTFE tape to ensure maximum pressure rating and longevity in demanding environments.
