The Nitrous Express Lightning 500 bottle valve for 10 lb bottles is a high-flow nitrous bottle valve machined from 6061-T6 billet aluminum and pressure tested to over 10,000 PSI for safety. The Lightning 45 design outflows typical valves by a factor of four to eliminate restrictive bottle bottlenecks and retrofits to most nitrous systems; it does not fit the NX DF 500 valve.
