This Reducer allows you to efficiently reduce the diameter of your ductwork run from 4” to 3”, typically to connect to systems and tools via flex-hose and/or machine adapters. This item includes the reducer only; you will require an additional O-ring if you're using this in conjunction with an adjustable sleeve.
This Reducer is constructed from heavy-gauge galvanized steel. The taper is lapped spot-welded and caulked. Features rolled-ends on each opening for use with Quick-Clamp Duct Clamps, allowing for easy adjustments and fast installations.
