NOS Nitrous Oxide Systems Refillable Nitrous Oxide Bottles

NOS (Nitrous Oxide Systems) has been the most trusted name in nitrous performance since pioneering automotive nitrous oxide injection in the 1970s. As part of the Holley Performance family of brands, NOS has powered more racers to the winner's circle than any other nitrous brand in the world. These refillable nitrous oxide bottles are the foundation of every NOS system — engineered for safe, reliable, and consistent N2O storage to deliver on-demand power across drag racing, street performance, and road race applications.

Key Features:

• DOT and CGA Approved — Every bottle in the NOS lineup is approved by both the Department of Transportation and the Compressed Gas Association, ensuring full regulatory compliance whether you're at the track or on the street.
• Factory-Installed Siphon Tube — Each bottle ships with a built-in siphon tube that ensures proper nitrous draw regardless of bottle orientation, maintaining consistent delivery from the first pass to the last.
• Exclusive Blow-Off Venting System — NOS engineered an integrated pressure relief system to protect against over-pressurization. In the event of overfilling or excessive heat exposure, the system vents and discharges bottle contents in a controlled, predictable manner.
• Hi-Flo Valve Assembly — A precision high-flow valve is included as standard equipment across the bottle lineup, delivering consistent, high-volume nitrous flow with reliable shutoff performance run after run.
• Aircraft-Quality Manufacturing Standards — NOS holds every component to strict high-pressure testing standards throughout the production process, providing confidence at every fill and every pass.
• Fully Refillable Design — Built for economical long-term use and compatible with NOS refill stations available at locations nationwide.
• Seamless NOS System Integration — Engineered to work directly with the full range of NOS nitrous kits and components for a complete, matched performance system.
• Multiple Configurations Available — The NOS bottle lineup is offered in a variety of sizes, constructions, and finishes to accommodate different vehicle builds, power levels, and installation requirements.

Nitrous oxide remains the most cost-effective way to add serious horsepower — delivering race-winning performance at a fraction of the cost of engine hardware upgrades while allowing a stock engine to retain its everyday drivability. Whether you're building a dedicated drag car, a street/strip dual-purpose machine, or a road race application, NOS nitrous oxide bottles provide the professional-grade, high-pressure N2O storage your system demands. All bottles are shipped empty and ready to fill at your nearest NOS refill location.
