6AN 18in Nitrous Line Black

The 6AN 18in Nitrous Line Black from REDHORSE PERFORMANCE is a purpose-built hose assembly engineered for high-pressure nitrous oxide delivery in performance and racing applications. Built to withstand the demanding conditions of forced induction systems, this 18-inch hose connects critical fuel and nitrous components with reliable precision. Whether you're building a street-legal performance vehicle or preparing a dedicated track car, a properly rated nitrous line is non-negotiable for system safety and consistent power delivery.

This assembly features a 6 AN (AN6) straight female-to-female configuration with braided stainless steel outer protection and a PTFE-lined inner core, which resists corrosion and maintains structural integrity under pressure cycling. The aluminum fittings are black anodized for durability and appearance, while the PTFE (Teflon) liner ensures compatibility with nitrous oxide without degradation. The 900 Series designation indicates REDHORSE's premium hose platform, designed to handle the thermal and pressure spikes typical of nitrous systems operating at peak boost levels.

This 18-inch nitrous line is ideal for custom engine bay layouts where factory routing doesn't apply, giving builders flexibility in feed-line placement between the nitrous bottle and injector rails or fuel rails. The straight female-to-female AN6 configuration integrates seamlessly with standard performance system components and allows swapping between configurations without replacing the entire line. Installation requires proper torque specs at both fittings to prevent leaks under pressure; always use AN thread sealant or PTFE tape on male threads. Compatible with all popular nitrous oxide delivery systems, this hose supports safe, repeatable power gains when paired with correctly sized solenoids and fuel enrichment.
