Says it is for 3386 but does not fit!
Would Not RecommendI have been ordering flappers for my Rialto 3386 toilet on the Kohler site for years. Was excited to walk into Lowes and this product was on the shelf. NOPE, doesn't fit. Not the right part. Come on Kohler! And why do I have to replace the flapper so many times anyway? Now I am out 11$ for the wrong flapper. Can't return it.

Worked great. Was the perfect part for my Repair.
Would RecommendFlapper seals / toilet tank parts, in general, are overpriced in my opinion. Honestly a piece of rubber shouldn’t cost more than 4 or 5 dollars. But, we have to have them, so I suppose it’s just a combination of manufacturing & retail markup.
