Vibrant 10174 45 Degree Adapter Fitting -4AN x 3/8" NPT

The Vibrant Performance 10174 is a precision-engineered 45-degree adapter fitting designed for high-performance fluid and fuel system applications. This compact fitting features a -4AN male flare connection on one end and a 3/8" NPT male thread on the other, oriented at a 45-degree angle to facilitate clean, space-efficient routing in tight engine bays.

Key Features:

• 45-degree orientation allows for optimized hose and line routing around obstacles
• -4AN male flare connection compatible with standard AN braided hose and fittings
• 3/8" NPT male threads for secure connection to ports, sensors, and components
• Precision CNC-machined from high-quality aluminum for strength and light weight
• Anodized finish provides corrosion resistance and professional appearance
• Ideal for oil, fuel, coolant, and other automotive fluid systems

This adapter fitting is commonly used to connect AN hose assemblies to NPT-threaded ports on engines, turbos, oil pans, fuel rails, and other performance components. The 45-degree angle eliminates sharp bends and reduces the risk of hose kinking while maintaining proper flow characteristics.
