10AN to 8AN(1/2)NPT Adapter 45

The REDHORSE PERFORMANCE 10AN to 8AN (1/2) NPT Adapter 45 Degree is a vital hydraulic and fuel line fitting designed for custom engine builds, turbo systems, and high-performance fuel injection setups. This adapter effectively bridges two common AN line standards while converting to NPT (National Pipe Tapered) port threads, making it essential for retrofitting OEM or aftermarket components into modified vehicles.

Manufactured from precision-machined aluminum, this compact 45-degree adapter is designed to handle the demands of various automotive applications. The stepped sizing (10AN male to 8AN female with 1/2-inch NPT) ensures compatibility across multiple system configurations, while the tapered thread design creates a reliable seal without requiring additional sealant tape. Proper installation with the correct torque is recommended to prevent stripped threads and ensure longevity.

This fitting is ideal for mechanics and enthusiasts upgrading fuel delivery systems on platforms such as LS, LT, Coyote, and EJ swaps. Its 45-degree angle geometry allows for optimal hose routing in tight engine bays, reducing potential leak points in your fuel or coolant circuit. Whether plumbing a fuel rail or an intercooler cooling loop, this adapter simplifies the installation process.
