KOHLER GENUINE PART GP1078440 FLAPPER (SHARK-FIN)

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.

Worked to fix Kohler toilet. Easy install.

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.

Good original part replacement.

This flapper was easy to install and fit my toilet. Unfortunately, the chain was too short, so I had to use the chain from the old flapper to make this new one work with my toilet.

OEM part - works as it should. Buy with confindent!

No more dripping.

I'd hoped the OEM part would be better than the knockoffs, but this is already leaking. OTOH, it's easy to replace, not particularly expensive, and the shark fin design prevents jamming up and mis-seating pretty well. This style fits a rectangular overflow tube that's about 2 1/4 inches wide. the flapper body is 3 inches wide, but is called a 2” flapper.

Funciona

Perfect fit. Easy to install.

No water seepage at all. Way better than similar universal one.

Que es exactamente para el tipo de baño que tengo. Evita fugas de agua.

This flapper works good (see type of toulet in the video). I had no idea if it would fit because i had a diffrent flapper before but could not find it anymore so i had to go with this one that's general. I don't understand why they make the chain so short, o mean a couple of links more would be better and definatly work for all 2" toilets. I do recomand buying this flapper if you don't find your old brand it should fit just fine just remember to keep a couple of links from thw old one. As for durability I can't say but i guess it ahould be the same as any other silicone flapper between 3-5 years to perform right. A+
