Nitrous Express introduced the nitrous industrys first servo powered bottle opener in 1999. It has been copied but never duplicated. NX now introduces the Next Generation in nitrous bottle openers. This unique new design will operate on most brand nitrous bottles and is lighter and sleeker than any available opener. Sure to be copied, but NXs Made in the USA quality will never be matched! Designed to work with NX Lightning Valves, but may work on other valves as well.
