Hey, if your garbage disposal is leaking from the top or you're installing a new one, this 1010A mounting gasket is exactly what you need! The 4-inch diameter and 3/4-inch height fits perfectly with most InSinkErator and Kenmore models. This upgraded gasket creates a watertight seal between your disposal unit and the sink flange, stopping those annoying leaks that drip into your cabinet. The splash guard part helps prevent water and food particles from splashing back up while you're using the disposal. Installation is super simple - just remove your old gasket (if you have one) and snap this new one into place. I replaced mine when I noticed water dripping, and it solved the problem completely. The rubber material is flexible but durable, creating a perfect seal without being too stiff. Whether you're dealing with a leaky disposal or doing a new installation, this gasket makes the job so much easier. Keep one on hand for plumbing emergencies - at this price, it's way cheaper than calling a plumber for a simple gasket replacement. Works like a charm and lasts for years!
