Mounting gasket FAQs
How do I measure an InSinkErator mounting gasket?
Measure the outside diameter across the outer edge and the inside diameter across the opening. For the bolt circle, measure from the center of one bolt hole to the center of the hole straight across from it. Then count the bolt holes and check the thickness.
What’s the difference between a baffled and a non-baffled gasket?
A baffled gasket has a rubber baffle across the opening. A gasket with no baffle is open in the center. Match the type your disposer has now.
Are these genuine InSinkErator parts?
Yes. We sell genuine OEM InSinkErator replacement parts.
What if my gasket isn’t listed, or I’m not sure which one I need?
Call (800) 654-3545 or text a photo of your old gasket with its measurements to (816) 710-8875, Monday–Friday 8 AM–5 PM Central, and we’ll find the right one.
