Part:

CAC182

$19.99
The Waring CAC182 drive coupling is compatible with all MX-series blenders*. When the factory-installed couplet becomes worn out or damaged, users can replace it with this component to keep the unit running smoothly. After it’s been installed, it self-tightens when the unit powers on.

*For models built after 5/7/21
