Rated 4.1 out of 5 by 23 reviewers.
Rated 5 out of 5 by Replacing tank gasket Once I read the directions it was very easy to replace. It only took a few minutes and no more leaks. December 17, 2014
Rated 5 out of 5 by Works well and eay install I know that some reviews have made negative comments about this gasket and stated that it was NOT OEM. Well the one I purchase was clearly OEM and was VERY easy to install and an improvement over the old gasket. However it should be noted that the old gasket was over 26 years old! December 10, 2014
Rated 5 out of 5 by Easy to install and works well I found it far more difficult to remove the old gasket because the old nuts were wing nuts. When I removed the old gasket I assumed that it would be very difficult to install the new gasket because the old gasket fits very tightly in the screw holes. When I installed the new gasket I found that it was very easy to slide the new gasket in, because as you tighten the included bolts, the gasket flatten and form fit to the three holes. I think it is very important that you tighten the bolts until they fit almost flush with the tank, otherwise it might leak. Some reviews have stated that this kit is not genuine Kolher gasket, but the one I purchased was. Since it was taking the toilet apart, I did change the Flush Value Shank Washer, for all of $2 more.

Rated 5 out of 5 by Great product Does exactly what it is made for, easy installation but by far the most expensive gasket I've seen. Comes with tank bolts with black hard plastic heads to avoid rusting. Forgot to mention the most important part... The gasket seals very well and the quality of the seal enhances as you tighten the bolts. March 11, 2014
Rated 5 out of 5 by Universal's are not - Use triangle gasket if you have Kohler Bought an internal valve set with a "universal" gasket. It was not and still had leaks. Bought the Kohler gasket, installed perfectly and no more leaking. Very easy to install and good instructions included. August 8, 2014
