6AN 2ft Nitrous Line Black

The 6AN 2ft Nitrous Line Black from REDHORSE PERFORMANCE is a critical fuel delivery component for high-performance nitrous oxide systems. Designed for serious engine builders and drag racers, this hose assembly transfers liquid nitrous from your bottle to the engine's intake manifold or fuel system with precision and reliability. Whether you're tuning a street machine or building a competition platform, proper nitrous fuel line sizing and construction directly impacts system response time, safety, and power delivery.

This line features a 6AN (6/8-inch outer diameter) fitting standard, the industry specification for moderate-duty nitrous delivery on carbureted and fuel-injected applications. The 2-foot length provides flexibility in routing around engine bays while minimizing dead volume—critical because excess hose volume delays nitrous charge delivery and reduces peak boost response when you need it most. Black exterior finish resists UV degradation and maintains a clean engine compartment appearance. REDHORSE PERFORMANCE's hose construction meets SAE J30R9 standards, ensuring the line withstands cryogenic temperatures and pressure spikes inherent to nitrous systems without cracking or leaking.

This 6AN nitrous line suits single-stage and progressive nitrous kits on naturally aspirated engines making 300–600+ horsepower. Install it between your bottle outlet and solenoid valve, or from the solenoid to your manifold entry point, depending on your kit's layout. Confirm your bottle outlet size and solenoid inlet rating match 6AN (-6 JIC or 37° flare) before purchase. Pair with compatible fittings, check valves, and a quality regulator for a complete, leak-free nitrous delivery system that responds instantly when you hit the button.
