SST/Teflon Hose Assembly

The NITROUS OXIDE SYSTEMS SST/Teflon Hose Assembly (part number 15345NOS) is an 18-inch braided stainless steel nitrous oxide delivery hose designed for high-flow, high-pressure applications in performance engine systems. This hose assembly features a PTFE (polytetrafluoroethylene) inner lining—commonly known as Teflon—which provides superior chemical compatibility and flow characteristics essential for nitrous oxide systems. The 3 AN straight male to 4 AN straight female configuration enables flexible integration into diverse nitrous plumbing layouts, while blue anodized fittings provide visual identification and corrosion resistance in underhood environments.

Constructed with braided stainless steel reinforcement, this assembly withstands the pressure spikes and thermal cycling common in forced induction systems. The PTFE inner tube resists degradation from nitrous oxide exposure and maintains smooth, unobstructed flow that maximizes system efficiency and spray atomization. The 18-inch length accommodates most engine bay layouts without excessive routing, while the compact 0.95-inch outer diameter fits within tight spaces around fuel rails, intake manifolds, and cylinder heads. At 0.17 lbs, the assembly adds minimal weight to the vehicle while meeting the material and pressure specifications required for reliable nitrous delivery.

This hose assembly is engineered for drag racing, street performance, and dedicated nitrous oxide system installations where component reliability directly impacts launch consistency and engine safety. Builders and tuners select NITROUS OXIDE SYSTEMS components for their engineering precision and track-proven durability. The dual-sized fittings (3 AN to 4 AN) allow seamless connection to factory nitrous lines, aftermarket controllers, or custom manifold designs. Proper installation requires verification of line routing to avoid contact with exhaust manifolds, alternators, or moving engine components.
