6AN Hard Line Adapters Blue

The 6AN Hard Line Adapters Blue from Redhorse Performance are designed for high-performance automotive applications, specifically for fuel system and coolant line modifications. These adapters are essential for transitioning between different hose configurations or integrating hard-line tubing into your vehicle's fuel delivery or cooling systems. They are ideal for custom builds, retrofitting carburetor setups, or upgrading coolant routing in both street and track cars.

Engineered to meet AN6 specifications on both ports, these adapters ensure consistent thread geometry and pressure ratings necessary for high-flow applications. The blue anodized finish not only enhances visual identification during assembly and troubleshooting but also provides corrosion resistance in engine bay conditions. Manufactured to tight tolerances, these adapters guarantee leak-free connections when used with proper hose crimping or swaging techniques.

These hard-line adapters are frequently specified by mechanics and tuners for various applications, including fuel rail upgrades, auxiliary fuel pump installations, intercooler coolant loops, and remote-mounted filter assemblies. They are compatible with AN6 hose fittings, braided stainless, and hard line, making them versatile for a range of high-performance setups. Whether you're enhancing a turbocharged or supercharged engine, these adapters provide the reliable connections needed for optimal performance.
