## Description

Strainer Gasket Seal Ring

Review: Easy to use, no mess, and invisible protection from leaks and drips - 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.
Review: Great! - This works SO MUCH BETTER than ‘Plumbers’ stuff that squeezes out, then leaks!
