Questions & Answers

Answer This Question

A:  Hi Ariel, Thank you for your query. If you own an Evolution garbage disposal, this part perfectly fits your sink with the InSinkErator® sink flange. You can pull out the old baffle in the sink opening and insert the new baffle with the “cone-shaped” side facing down. Make sure the groove on the quiet collar is engaging the "lip" on the flange all the way around.

    Q:My new sink came with a decorative disposal flange. It's supposed to fit into the metal collar of the disposal and has a strainer that closes the drain. Will this fit under that or is that a replacement for this?

    A:  Hi Lmont, thank you for the question. This sink baffle is compatible with Evolution series disposers. It should be placed inside the sink flange and below the stopper that covers your drain.

      A:  Hi Ariel, thank you for the question. This anti-microbial quiet collar sink baffle for the Evolution disposer can be easily installed. You only need to insert it into the sink hole opening with the “cone-shaped” side facing down. Make sure the groove on the quiet collar is engaging the "lip" on the flange all the way around. This should fit perfectly as long as you're using the InSinkErator® sink flange.

        Q:Will this gasket fit my Emerson 777ss aerator

        Answer This Question

        A:  Hi Kathleen, thank you for getting in touch with us. This sink baffle is not compatible with your 777SS disposer. You can search for the standard mounting gasket with the model number SMG-00 for the mounting gasket of your disposer and the removable sound baffle with the model number RSB-00 for your sink baffle needs.

          On my 6th replacement
          These do not last very long at all. I order them in 2’s so I always have a backup. They are flimsy and tear easily. They do keep the water from splashing up but they do not hold up and they trap food in the nooks and crannies.

            Different than Original
            I've got an evolution series and love it. The original baffle is noticeably thicker and the design is a little more restrictive than the 2022 replacement. The new design has thinner rubber and presumably will allow food to pass through more easily. It does not fit as snug into the metal ring. It also seems a little louder. After using the previous baffle for several years I've grown accustomed to pushing food down which is actually quite nice since the previous baffle prevented objects like spoons from accidentally falling into the disposal. This replacement baffle seems like it was designed to allow things to pass through more easily. If I had a choice I would choose an identical replacement.

              Slipped right in the disposal
              Correctly described and advertised.

              These aren't the same as the original
              I don't understand how a company that makes such an amazing garbage disposal can make such a garbage replacement baffle. The original baffle lasted several years that came with the disposal. But when it finally became so worn, I replaced it with an insinkerator oem baffle, and had to every couple of months because they will not hold their shape. The top part of the baffle expands so much that creates huge wrinkles so the stopper can't be installed. And the spaces around the seal traps food and unless you constantly remove and clean, it can become quite foul smelling. I've gone through probably a half dozen of these and am getting ready to try an off brand replacement. These are not the same quality as the ones that come with the disposal, so hang on to the original one as long as possible, because you won't ever get another one like it to replace it

                I have an insinkerator garbage disposal and after so many years, these things need to be replaced. it works great, does its job and super easy to install. it just pops right in. it's also antibacterial. I would recommend this product.

                  This is the only baffle that drains correctly and allows food to pass through easily. I bought this to retrofit an American Standard disposer. Fit compatibility is perfect

                  Smelly Odor
                  The rubber stopper holds food on the underside. I’m constant having to pull it out and clean it. It smells so bad. Is there another version of the rubber stopper that does not catch the food?

                    Changed out my rusty drain and gunked up splash guard. Big difference in appearance. This thing looks great! And note most of the 'one star' bad negative reviews are from people that bought the wrong size splash guard. Not sure how they're reviewing the product when they made the mistake of buying the wrong one. It clearly says one disposals the splash guard works on in the packaging. It does what it's supposed to. It's a sink splash guard. Nothing crazy.

                      Has this problem finally been fixed been fixed?
                      I've experienced exactly the same no-drain problem with my InSinkErator for years. Yesterday I installed the baffle shown above, and it works perfectly. I do notice there are other original-equipment parts out there with a different design and exactly the same name. Maybe the company has finally updated the part, or maybe it's just sloppy about ID'ing its baffles. The one I have is called a "Quiet Collar Sink Baffle." Its package describes the part as an "E606 Accessory" and as a "QCB-AM" (see attached scan). The baffle itself is made of thin and extremely flexible rubber (unlike the much more rigid previous baffle), and allows waste (and water) through easily, as it should.
