Product Description
4" to 2-1/4" Eccentric Reducer – Dust Collection Adapter
Optimize your dust collection system with this 4" to 2-1/4" eccentric reducer—designed for woodworkers who need efficient airflow transition, secure hose connections, and reduced clogging. The off-center (eccentric) design helps maintain airflow velocity while minimizing dust buildup inside your system.
This fitting allows you to step down from a 4" dust collection hose to a 2-1/4" shop vacuum hose or port, making it ideal for connecting larger dust systems to smaller tools and machines.
Important Compatibility Note: This reducer is specifically designed to work with a 4" ID dust collection hose and 2-1/4" ID ports. It is NOT intended to fit a 4" OD machine port directly. For 4" OD connections, use POWERTEC 70149 or 70369 flex cuffs.
