The Water Pump Hose Adapter 3/4in NPT x 12AN is a precision fluid-transfer fitting designed for high-performance cooling systems, fuel lines, and hydraulic applications. It is ideal for technicians and enthusiasts working on racing engines, custom water circulation systems, and heavy-duty machinery.
This adapter bridges the gap between NPT (National Pipe Thread) and AN (Army-Navy) standards, ensuring seamless compatibility and zero-leak performance. Manufactured from aluminum with a clear anodized finish by CSR Performance, the 909AN12 provides corrosion resistance and lightweight durability essential for engine bays and pressurized systems.
The compact weight of 0.17 lbs ensures minimal system stress, while the precisely machined bore minimizes turbulence and pressure drop during coolant circulation. This fitting is best paired with compatible AN hose assemblies and NPT-threaded pump ports, commonly found in small-block and big-block racing engines and marine cooling loops.
