## Description

Product Description Protect the on KOHLER products, always look for the KOHLER GENUINE PARTS logo. KOHLER GENUINE PARTS are designed by KOHLER engineers to maintain original product performance and promote product longevity.

From the Manufacturer Kohler Genuine Part, Toilet Flapper, Used in various one piece toilets.

Review: Perfect fit, easy installation. - When I remodeled my bathroom I installed a Kohler toilet. It is a quality fixture that is still going strong. The only thing that I had issues with was a faint trickle of water that kept going into the bowl. That indicated that the flapper had seen better days, it was not making a good seal and it was time for a replacement (just take a look at my photo and compare the old and new one. LOL!) To make sure I ordered the correct part I looked at the model of the flushing equipment in the tank and from that I found the correct flapper. There were other makers that make flappers that would also fit my toilet. The difference in price was less than $5, a negligible amount between a genuine Kohler part and a knockoff. So of course I got the real deal. Installation was less than 2 minutes, from shutting off the water feeder valve to reopening it again and flushing the toilet to test it. Works like a charm and no more trickling water in the bowl. If you have a Kohler toilet find the model of the existing flushing equipment (written on the top of the plastic tube inside the tank) and from that find which flapper you need.
Review: OEM product, works great - Worked to fix Kohler toilet. Easy install.

Worked to fix Kohler toilet. Easy install.

### ⭐⭐⭐⭐⭐ Confirm compatibility by dimensions, not just model numbers
*by A***R on January 11, 2026*

Ordered this for my Kohler San Raphael (2002). I was happy to finally find a replacement flapper specifically for my toilet model. I’ve been using universal flappers the last few years and they always eventually end up being too large and wobbly for my toilet, which leads to the constant running water issue. My exact model number was listed on the product listing and even on the packaging for this flapper, however it ended up being too small. I honestly thought I was losing my mind and kept trying different ways to make it work… but it’s simply too short. When installed it sits too snug and stays partially open. I tried repositioning it on the back multiple times and nothing fixed it. I can’t leave a bad review for this because the product seems very good quality and it was easy to install. It just didn’t fit. I did however return it and eventually found the correct part for my toilet, which was just a touch longer, and now everything works perfectly. Just a heads up to double check measurements, because even toilets from the same model line may require different flapper lengths depending on the year or configuration. Bottom line: confirm compatibility by dimensions, not just model numbers, to save yourself the frustration.
