This Eccentric Reducer provides a step-down from a larger main line to a smaller branch line. This step-down increases air velocity near the machine where it's needed the most. 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.
