NOS Nitrous Oxide Bottle Valve Opener

NOS Nitrous Oxide Bottle Valve Openers: Precision Flow from the Pioneers of Nitrous

When it comes to nitrous performance, few names carry the weight of NOS (Nitrous Oxide Systems). Born in the late 1970s, NOS spent its early years proving that nitrous oxide was a safe and efficient form of performance enhancement — and that dedication to quality extends all the way to the smallest, but most critical, components of any nitrous setup: the bottle valve opener.

A nitrous oxide bottle valve opener is the gatekeeper of your entire system. It controls the flow of N2O from the bottle to the rest of the delivery system, and choosing the right valve directly impacts both performance and safety. NOS has engineered a range of nitrous oxide bottle valve openers that span everything from basic manual hand-wheel designs to electronically-actuated remote openers, giving builders and racers the right solution for every application.

The NOS Valve Opener Lineup

NOS offers several distinct valve opener styles, each engineered for a specific use case:

• Hi-Flo™ Nitrous Bottle Valves — Featuring large internal ports, CGA 660 outlet threads, and an O-ring bottle seal, the Hi-Flo valve is a proven workhorse capable of supporting systems rated at 400+ HP. The current generation is identified by its distinctive 45-degree handwheel orientation, updated from earlier 90-degree designs for improved ergonomics.
• Super Hi-Flo Valve Assemblies — NOS offers Super Hi-Flo valve kits for larger 10 lb., 15 lb., and 20 lb. bottles. These complete assemblies come with a siphon tube and nitrous pressure gauge pre-installed, making them a direct drop-in upgrade. The siphon tube is constructed from 6061 aluminum with a 3/8" I.D. for maximum flow, and the 1-1/2" diameter pressure gauge features stainless steel and brass construction for accurate readings.
• Mini Hi-Flo Valves — Designed specifically for smaller 1 lb., 2 lb., and 2.5 lb. bottles with 3/4-16 UNF threads, these compact valves include a pre-installed PRD (Pressure Relief Device) and a fresh O-ring seal, making them ideal for powersports or secondary bottle setups.
• Remote Bottle Opener (Electronic) — For racers and street-performance enthusiasts who want true cockpit control, NOS produces an electronic remote bottle opener that operates on 12 volts DC. A simple switch activation opens or closes the bottle valve without ever touching the bottle — ideal when the bottle is mounted in a trunk or remote location.
• Billet Hand Wheel Openers — NOS also offers billet hand wheel valve openers, such as the 16147NOS, featuring a 2-3/4 in. black billet wheel for a premium look and confident grip during manual operation.

Why Choose NOS Valve Openers?

NOS is the brand that effectively defined nitrous oxide as a mainstream performance category.

Every component in their lineup — including valve openers — reflects decades of real-world racing feedback and continuous refinement. Whether you are upgrading an existing NOS bottle or building a new system from scratch, NOS valve openers are engineered to be direct-fit, reliable, and flow-optimized for the performance demands of today's engines.
