6AN Anodized Hose Finisher Black

The 6AN Anodized Hose Finisher Black from REDHORSE PERFORMANCE is a precision-engineered hose end cap designed for high-performance automotive fuel, coolant, and brake line systems. Whether you're building a custom engine bay, upgrading a race car's fuel delivery system, or refining the aesthetics of an engine compartment, this finisher addresses both form and function in modern vehicle modifications. AN (Army-Navy) hose standards remain the industry benchmark for fuel injection systems, turbocharged platforms, and competition vehicles where reliability and clean appearance are non-negotiable.

Built from anodized aluminum, the 6AN finisher delivers corrosion resistance and a professional black finish that complements modern engine bays and custom builds. The anodized process creates a hard oxide layer that withstands vibration, thermal cycling, and exposure to fuel, coolant, and brake fluid without degrading or discoloring. This hose finisher serves as a cap or termination point for AN hose runs, sealing unused ports while maintaining system cleanliness and preventing contamination. The compact design—measuring 2.8 x 1.15 x 3.8 inches and weighing just 0.05 lbs—integrates seamlessly into tight engine compartments without adding weight or bulk to your build.

Mechanics and performance enthusiasts benefit most from this finisher when configuring custom fuel systems, managing multiple line runs, or capping redundant ports during engine swaps and turbo installations. Installation is straightforward—simply thread the 6AN finisher onto the corresponding hose or port adapter using standard AN wrenches, ensuring secure sealing without the need for additional fittings. This product pairs perfectly with REDHORSE PERFORMANCE hose kits, fuel rail assemblies, and custom plumbing on turbocharged engines, LS swaps, and competition vehicles. Proper sizing and thread compatibility with your existing 6AN infrastructure ensures leak-free operation under pressure and thermal stress.
