I think most exhaust fans use a 3 inch tube. I know because we recently installed a dryer vent which is four and grabbed the wrong flexible/extendable tubing.

Thanks for the tip! I am using an indoor grow tent for an enclosure I was planning to use a fan from the same company that makes the tent. It is listed as a 4-in fan
