KONE Strainer Gasket Seal Ring, 2 Pack Rubber Gray Washer Fits for 3-1/2 Inch Kitchen Sink Drain No Need Plumber Putty…

I was researching how to install a new garbage disposal, and came across a suggestion to use these gasket rings at the sink interface instead of plumbers putty. I had my kitchen redone a couple years ago, and one of the things I didn't like about the sink was the messy look of the dried putty the contractor left behind. Oh, and it also eventually started cracking and then ultimately leaking. So I figured I'd give these rings a try and I'm glad I did. There's absolutely no mess, no working with putty, and very little waste generated unlike a jar of putty that unless you're a contractor you're very unlikely to use all of. Once installed (and "installation is a bit misleading because all you have to do is put this ring in place) and after getting the disposal tightened in place, the ring is invisible, giving my sink a cleaner look. While I had all the towels in place I did some tests and didn't find any leaks. That was a couple weeks ago, and -- fingers crossed -- still dry where it's supposed to be. I would recommend these to anyone installing or replacing a disposal under their sink.

made installing the drain much easier vs using the paste.

Easy to install.

I wish I had these the first time i installed the sink, so much better than that putty stuff

In my SS sink application, plumbers putty didn't work (squeezed out after a month when the strainer basket nut was tighten sufficiently to stop leakage.) Trying this Kone gasket alternative worked for me.
