10AN Crimp Style Hose End Black 45

The REDHORSE PERFORMANCE 10AN Crimp Style Hose End Black 45 Degree is a precision aluminum fitting engineered for high-pressure fuel, coolant, and fluid transfer applications in performance automotive systems. This 45-degree angle connector accommodates 10 AN hose to 10 AN female ports, making it essential for custom fuel rails, turbo cooling loops, transmission coolers, and engine bay plumbing where space constraints or hose routing require an angled approach rather than a straight connection.

The 10 AN size designation indicates a hose inner diameter of 5/8 inch, rated for high-pressure fluid systems commonly found in turbocharged and supercharged engines, as well as custom cooling and fuel delivery setups. The crimp-style construction means this fitting is permanently secured to hose using a specialized crimping tool and die set, creating a leak-free bond that withstands extreme pressure cycles and vibration. Black anodized aluminum construction provides corrosion resistance and a clean appearance while keeping weight minimal—critical for performance builds where every ounce counts. The 45-degree angle allows hose runs to navigate tight engine compartments and reduces stress on adjacent components by eliminating sharp bends in the hose itself.

This fitting is designed for builders, fabricators, and enthusiasts assembling custom fuel systems, high-output cooling circuits, and modified engine bay plumbing. Whether upgrading a forced-induction platform, installing an auxiliary cooler setup, or building a custom fuel distribution manifold, the 10AN crimp hose end connects securely to existing female port receivers. Compatibility with standard crimping equipment and availability of matching male and female AN fittings in the REDHORSE catalog makes system assembly straightforward for DIY and professional shops alike.

AN (Army-Navy) sizing remains the industry standard in performance automotive because it simplifies system design across diverse platforms and scales to any pressure or flow requirement. The 45-degree configuration is preferred over 90-degree or straight fittings when hose routing demands space efficiency or when angled entry to a port reduces turbulence and component stress.
