Hose Fitting #12 180 Deg Pro-Flow Black

The FRAGOLA Hose Fitting #12 180 Deg Pro-Flow Black (part number 231812-BL) is a 180-degree aluminum hose end designed for 12 AN connections in high-performance fluid systems. This swivel fitting accommodates 12 AN hose to 12 AN female ports, making it essential for fuel lines, oil cooler circuits, and hydraulic applications where space constraints require tight directional changes. The black anodized aluminum construction provides corrosion resistance while maintaining the lightweight profile critical in racing and performance applications.

FRAGOLA's Pro-Flow series represents the standard for professional-grade hose fittings in motorsports and custom fluid system fabrication. The 180-degree configuration allows hose runs to fold back on themselves, maximizing engine bay efficiency on vehicles with tight packaging. The swivel design prevents line twist and reduces stress on both the fitting and hose during installation and vibration cycles—a practical consideration for vehicles operating under high RPM or heavy acceleration. The 12 AN sizing handles substantial flow rates while remaining compatible with standard -12 hose, adapters, and manifold ports found across street rods, race cars, and marine applications.

This fitting is specified by builders working on fuel-injected conversions, forced induction systems, remote oil filter setups, and custom cooling circuits where standard 90-degree elbows won't fit the layout. Engine builders and fabricators choose FRAGOLA Pro-Flow fittings for their dimensional accuracy and pressure rating integrity. Whether you're routing lines around engine bay obstacles, creating compact manifold assemblies, or upgrading existing fuel systems, the 180-degree orientation eliminates the need for multiple adapters and ensures leak-free connections in demanding environments.
