The 4AN STR Male Adapter 3/8in NPT Male Blue from Redhorse Performance is a precision hydraulic adapter designed for high-performance fuel, oil, and coolant line systems in modified vehicles. It is ideal for both automotive enthusiasts and professional mechanics who require reliable, leak-free connections in custom engine bay layouts.
This adapter features a 4AN hose connection on one end and a 3/8-inch NPT male thread on the other, facilitating seamless integration between AN-rated braided hose systems and standard NPT ports. The blue anodized aluminum finish provides corrosion resistance and serves as a visual identifier for coolant or water lines in color-coded system layouts.
Builders integrating custom fuel delivery systems, remote oil filtration setups, or auxiliary components will benefit from this adapter's precision engineering. Redhorse Performance's quality machining ensures tight tolerances that prevent weeping or failure under sustained pressure, making it critical for turbocharged and supercharged applications where system reliability is paramount.
