We engineered the inside diameter of the 2-1/2-inch side of this fitting to duplicate the 2-1/2-inch opening on your Shop-Vac. Insert the Shop-Vac brand hose to the vacuum and the other end to one of these fittings to power the dust collection system. The outside diameter matches our standard dust collection hose to function as regular reducers.
