The Zex 10lb Nitrous Bottle with Valve is an exact replacement for the bottle that comes with most Zex Nitrous Kits when originally purchased. Whether you're adding a bottle, want an extra bottle for quick swaps when its time to fill, or even have another brand of nitrous kit and like the look/design of the Zex bottle, this bottle will meet your needs! The bottle features a high flow bottle valve, good for applications up to 300 HP and has a polished finish that not only is show quality, but is resistant to chipping and scratches.
