UTAS API 671 Standard bolted coupling designs range from 6-inch overall diameter to 22.5-inch overall diameter for use in light- to heavy-duty applications. The bolted design configuration gives us greater flexibility to create custom designs using various material and diaphragm profiles.
Each bolted coupling selection can be customized for your application.
* Contact Collins Aerospace engineering for coupling selections requiring: higher speed, axial/angular misalignment or torque.
