Female 45 Degree Union A dapter; Size: -12AN

The Female 45 Degree Union Adapter in -12AN size is a precision hydraulic and pneumatic fitting engineered for systems requiring offset connections at a 45-degree angle. Manufactured by Vibrant Performance, this adapter is designed for performance enthusiasts and professional technicians who need reliable, leak-free connections in high-pressure applications. Whether you're building a custom cooling system, fuel delivery circuit, or pneumatic line routing, this fitting eliminates the need for multiple components while maintaining system integrity and flow efficiency.

This female 45-degree union adapter features aluminum construction with black anodized finish, providing both weight savings and superior corrosion resistance for longevity in demanding environments. The -12AN port size (nominal 3/4-inch diameter) delivers substantial flow capacity while the 45-degree angle design reduces turbulence and allows for compact system layouts where straight connections are impractical. Black anodizing protects against oxidation and UV exposure while creating a professional appearance that integrates seamlessly into custom builds and engine bays.

Perfect for street rods, race cars, performance trucks, and motorsport applications, the -12AN female-to-female configuration accepts industry-standard AN hose fittings on both ends. Installation requires a simple push-on or compression connection depending on your hose assembly, and the compact 4.45 x 1.7 x 5.6-inch profile fits tight engine compartments and custom plumbing scenarios. This single unit (0.17 lbs) replaces bulkier manifold solutions and ensures your system flows efficiently while maintaining the pressure ratings demanded by modern fuel injection, nitrous, cooling, and air systems.
