Hose Fitting #12 45 Deg Pro-Flow Black

The FRAGOLA Hose Fitting #12 45 Degree Pro-Flow Black (224512-BL) is a high-performance hydraulic and fuel system adapter engineered for custom plumbing applications in high-flow environments. Constructed from aluminum with black anodized finish, this 45-degree hose end fitting provides secure, leak-resistant connections in fuel delivery systems, power steering circuits, and custom engine bay layouts where space and routing efficiency are critical.

The 12 AN (AN12) designation indicates this fitting accommodates hose with a nominal ID of 0.750 inches, meeting SAE J518 standards for aerospace-grade fluid power systems. The 45-degree geometry optimizes routing around engine components and transmission assemblies, reducing sharp bends that compromise flow efficiency and accelerate hose degradation. The swivel feature allows rotational adjustment during installation, critical for achieving proper hose alignment without twisting the hose itself. Black anodized aluminum resists corrosion in engine bay environments while maintaining thermal performance superior to steel alternatives.

This fitting serves builders and technicians working on fuel injection systems, turbocharger boost circuits, and fuel cooling loops where precision plumbing and reliable connections are non-negotiable. It's particularly valuable in applications demanding custom routing—street rod builds, motorsports engine conversions, and marine propulsion systems—where stock fittings conflict with component placement or hose path geometry. The 2000 Series Pro-Flow line from FRAGOLA is recognized for consistent thread tolerances and proven durability across high-pressure fluid transfer roles.
