About This Reducer

Keep your airflow strong from one duct size to the next, so suction does not drop where the pipe steps down. This reducer joins 4 inch and 2-1/4 inch duct with a tapered inside, so air moves smooth and you lose less pull. It is printed in PETG, so it stands up to shop heat and solvents and will not crack like brittle PLA. Both ends are a friction fit, so they push together with no clamps or tape in most setups.
