W1044—4" to 2-1/2" Reducer


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 vacuum. Insert the shop vacuum hose directly to the 2-1/2-inch side of the fitting. The outside diameters match our standard dust collection hose to function as regular reducers. Please note that this item is not designed to fit directly to a machine's dust collection port. To connect directly to a standard dust port, use with D4620 Double-Sided Quick Connect.


  • 4" & 2-1/2" Outside Diameter
  • ABS Plastic
  • To connect directly to a 4" port, use our optional D4620 Quick Connect
