Antimicrobial Quiet Collar Sink Baffle QCB-AM (Evolution Series)

I purchased the InSinkErator Antimicrobial Quiet Collar Sink Baffle (QCB-AM) as a replacement splash guard for my Evolution series garbage disposal after first trying a cheaper, inauthentic alternative. The difference was immediately noticeable. With the off-brand replacement, my sink drained noticeably slower, even though it appeared to fit correctly. After switching to this titled 100% authentic InSinkErator part, normal drainage was restored right away. The disposal performs as expected, with no water backing up in the sink. One key difference I noticed is the rubber quality. This component feels softer and more flexible than the cheaper replacement, which may explain the improved drainage and overall performance. It seals properly without restricting water flow, while still doing its job as a splash guard and sound reducer. Installation was quick and easy, fit was perfect, and the antimicrobial feature is a nice added bonus for long-term cleanliness. Although I would still recommend removing it periodically for cleaning and eventually replace. While it costs more than generic options, it’s absolutely worth it for proper performance and peace of mind. Bottom line: If your sink is draining slowly after replacing the insert, don’t waste time, or money, buying knockoffs. This titled genuine InSinkErator replacement part works exactly as intended.

Easy to replace - fit like a glove, just slid into place. So far seems to be keeping clean - the old one got gunky underneath. This one is thinner in the center material, which makes it easier to push food through and gives less resistance to water running through. So far the antimicrobial seems to work.

prefect fit and perfect replacement

My Insinkerator is from the early 2000s and still works good. The baffle had started disintegrating in the past couple of years. My wife wasn't happy looking into the innards of the drain so asked me to fix it. The old models use a baffle that is one-piece with the gasket that goes between unit and sink. There is an upgrade kit that includes a two-piece seal and baffle for older units, but you still have to remove the unit from below to install the seal between unit and sink, and then you can pop the baffle in from top. This baffle says it's only for newer units. BUT, if you carefully cut or tear off (assuming it was falling apart as mine was) the old baffle, this one fits perfectly from the top. Nothing to unbolt from below, just pop this in. Now, it looks like new!
