InSinkErator 抗菌静音カラーシンクバッフル QCB-AM (革命シリーズ)。

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.

Es Original

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

It’s truly amazing that there are any severely negative reviews of this item. It fits perfectly in my Evolution series OEM drain collar, water flows through it unimpeded at maximum faucet flow and it seals 100% when the original drain stopper is inserted. It’s new, so no confirmation of the anti-microbial properties as yet. True, it is less “robust” than the original, but that is likely by design (remember all the complaints about how hard it was to push waste through the previous version!) The quality of the rubber and manufacturing are top rate. I have no doubt that this is an authentic factory replacement. Just one thing to be aware of, it’s a snug fit and easy to think that it’s seated properly when it isn’t. There is a groove at the very bottom of the drain collar, just above the bottom lip, and a slightly raised ridge above the groove (look at the side of the rubber insert and you’ll see what you’re dealing with.) I suspect that many encounter the resistance at the top ridge and think they’ve got it, when they don’t. Pressing down more firmly will expose this situation, when the insert slips down into the groove (its fully seated position.) To accomplish this more confidently (once partially installed to the top of the ridge), push down in just one place along the edge of the insert to get it started and then work your way around until it’s completely down in the bottom groove. My original insert was about 5 years old and in pretty good shape. Recently, an unsuccessful attempt to clear a clogged drain with Liquid Plumber resulted in its being submerged for more than a day in the nasty corrosive mixture until an actual plumber came to fix the problem. Unfortunately, that was the end of the road for the original insert (not so good for the stainless either, I had to scrub away the surface layer to restore its original luster.) Expensive lesson learned, next time I’ll just call a plumber (still expensive, but would’ve been significantly less so.)
