Fitting 45 degree Male -10 AN to Male Straight

The Vibrant Performance Fitting 45 degree Male -10 AN to Male Straight (MPN 16948) is a precision hydraulic adapter engineered for high-flow fuel, oil, and coolant systems in performance and custom automotive applications. This adapter is essential for builders who need to navigate tight engine bay layouts or redirect line paths without compromising flow integrity. Whether you're fabricating a custom fuel system, upgrading a turbo feed line, or rerouting transmission cooler lines, this 45-degree elbow fitting solves clearance challenges while maintaining AN system standardization.

Constructed from aluminum and finished in black anodized coating, this male-to-male adapter features robust O-ring swivel technology that reduces installation stress and allows tool-free final positioning once hose connections are secured. The 45-degree angle geometry provides superior bend relief compared to 90-degree fittings, lowering vibration-induced fatigue at the connection point—critical in race and high-horsepower builds where hose whip and pressure pulsation can cause premature failures. The 10 AN sizing handles flows typical of LS engine fuel systems, twin-turbo oil circuits, and modern radiator bypass configurations without restrictive pressure drop.

This fitting is ideal for custom street rods, drag racing platforms, and engine swap projects where factory hose routing is impossible. Compatibility extends across any system using standard -10 AN male threads—fuel rails, oil cooler bundles, supercharger feed lines, and catch can plumbing all benefit from this adapter's space-saving geometry. Weighing just 0.05 lbs, it adds negligible mass while saving multiple pounds through simplified routing that eliminates redundant adapters. Installation pairs easily with standard -10 AN hose ends and compression fittings; torque to manufacturer specs (typically 18–25 ft-lbs for swivel connections) to ensure leak-free operation.
