-4an 6ft. Nitrous Hose w/Blue Ends

The -4AN 6ft. Nitrous Hose with Blue Ends (SKU: NOS15260) is a purpose-built fuel delivery line engineered for high-flow nitrous oxide systems. Built by Nitrous Oxide Systems—the industry standard for forced induction components—this hose connects your nitrous bottle to your system's distribution block with absolute reliability under boost conditions. Whether you're running a street car with occasional weekend pulls or a dedicated track machine, this hose delivers the consistent flow rate and pressure integrity your nitrous setup demands.

The -4AN 6ft. Nitrous Hose features dual 4 AN straight fittings (4 AN to 4 AN female configuration) with proprietary blue anodized aluminum ends that resist corrosion and provide visual identification in tight engine bays. The core utilizes PTFE (polytetrafluoroethylene) inner tube with braided stainless steel reinforcement, a combination that handles nitrous oxide's extreme cryogenic temperatures and pulsing pressure cycles without degradation. At 72 inches end-to-end, this length bridges most setups from bottle location to manifold injection points while maintaining minimal flex under acceleration. The stainless braiding also provides abrasion protection against engine heat, fuel lines, and serpentine belts—critical factors in turbocharged or supercharged bays where component density is high.

This hose suits both naturally aspirated and forced-induction vehicles running Nitrous Oxide Systems components or any system with standard 4 AN ports. Installation requires basic line routing through the firewall or along the frame rail; the flexible braided design allows bending without kinking, though avoid sharp radius turns that exceed the hose's minimum bend diameter. Weighing just 0.45 lbs, it adds negligible rotational mass. Whether you're upgrading from rubber fuel line or replacing a worn section, the -4AN 6ft. Nitrous Hose meets DOT and motorsport standards for pressurized cryogenic fluid transfer.
