New to the updated INF-2 is a built-in hook to hang the inflator when not in use. We had an early version of the original, and the new one is a big improvement. Not only does the INF-2 weigh about half as much as the original, but the galleries that carry air through the body to the head have also been enlarged for better flow, making quick work of seating tubeless tires. What′s more, it accepts any 3/8″ NPT male threaded fitting, and is completely rebuildable.
