Thank you for contacting InSinkErator®.
The replacement sink baffle or mounting gasket for your Badger disposer is the standard mounting gasket included in the InSinkErator Mounting Gasket Kit (MGK-00).
The Mounting Gasket Kit includes one standard and one deluxe mounting gasket. These gaskets are properly labeled. To ensure proper installation, please make sure to use the appropriate gasket for your disposer. I have included a link below for your reference.
