## 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, Flush Valve Seal, Seal flush valve to tank.

Review: It worked with some effort - This is the seal for the flush valve housing. It is for single piece Kohler toilets. In particular, I used it on T33 UPC K3425. It stopped all the dripping and leaking which came from the old seal. The installation was not a breeze, I'm afraid. After removing the flash valve and the old seal, I had a difficult time reinstalling the flash valve as it attaches to the toilet tank against this new seal. I must have tried a dozen times. Eventually, I brute-forced it at the risk of breaking the flash valve clips, but it eventually worked. I will still give it five stars.
Review: Stopped a leak - This was what I needed to stop a leak in my Kohler one-piece Rialto toilet flush valve. Followed some tips after searching online (putting it in warm water to soften, and using a tennis ball to push down when installing) and it was easy to get in place.

### ⭐⭐⭐⭐ Perfect fit
*by C***R on August 5, 2018*

Fit perfectly for my Kohler 3402BP and it's triangle hole. I only gave 4 stars since there was black reside that came from the gasket when pressure was applied. Hard as hell to get off your hand.
