The -4AN to 10mm x 1.25 Metric Straight Adapter from Vibrant Performance is a precision hose fitting engineered for fuel, oil, coolant, and vacuum line routing in modern performance and modified vehicles. This adapter bridges AN (Army-Navy) standard -4 hose sizing with metric 10mm x 1.25 threaded ports, making it essential for builders integrating aftermarket fuel systems, turbo setups, custom cooling loops, or engine management components.
The straight configuration (zero bend angle) simplifies line routing in tight spaces and reduces turbulence in fuel and coolant circuits, improving flow efficiency and system responsiveness. Vibrant Performance fittings are manufactured to tight tolerances and feature forged brass construction that resists corrosion and handles sustained pressure cycles in demanding engine bay environments.
Engine builders, turbo installers, and fuel system integrators rely on this adapter when converting between different fitting standards. The 10mm x 1.25 metric thread pitch mates seamlessly with OEM and aftermarket components common in import and performance platforms, while the -4AN hose interface accepts standard braided stainless or PTFE-lined hose with JIC-style swaged ends, ensuring compatibility across your entire fuel or cooling system architecture.
